• Interview Question: What are the characteristics of a good programmer?

  - by froadie

  I was asked this question on an interview a few months ago - "What would you say are the characteristics of a good programmer?" What would you answer to this? What, as a hiring manager, would you be looking for in an answer? I did get the job and am currently working with this company, although I don't know if that means I answered what they wanted to hear, but here were a couple of the points I mentioned: Passion PATIENCE Logic Teamwork etc. I'm especially curious to hear from the hiring side of things what would impress as an answer...

• Interview Q: given an array of numbers, return array of products of all other numbers (no division)

  - by polygenelubricants

  I was asked this question in a job interview, and I'd like to know how others would solve it. I'm most comfortable with Java, but solutions in other languages are welcome. Given an array of numbers, nums, return an array of numbers products, where products[i] is the product of all nums[j], j != i. Input : [1, 2, 3, 4, 5] Output: [(2*3*4*5), (1*3*4*5), (1*2*4*5), (1*2*3*5), (1*2*3*4)] = [120, 60, 40, 30, 24] You must do this in O(N) without using division.

• SQL SERVER – SQL Server Misconceptions and Resolution – A Practical Perspective – TechEd 2012 India

  - by pinaldave

  TechEd India 2012 is just around the corner and I will be presenting there in two different sessions. On the very first day of this event, my presentation will be all about SQL Server Misconceptions and Resolution – A Practical Perspective. The dictionary tells us that a “misconception” means a view or opinion that is incorrect and is based on faulty thinking or understanding. In SQL Server, there are so many misconceptions. In fact, when I hear some of these misconceptions, I feel like fainting at that very moment! Seriously, at one time, I came across the scenario where instead of using INSERT INTO…SELECT, the developer used CURSOR believing that cursor is faster (duh!). Here is the link the blog post related to this. Pinal and Vinod in 2009 I have been presenting in TechEd India for last three years. This is my fourth opportunity to present a technical session on SQL Server. Just like the previous years, I decided to present something different. Here is a novelty of this year: I will be presenting this session with Vinod Kumar. Vinod Kumar and I have a great synergy when we work together. So far, we have written one SQL Server Interview Questions and Answers book and 2 video courses: (1) SQL Server Questions and Answers (2) SQL Server Performance: Indexing Basics. Pinal and Vinod in 2011 When we sat together and started building an outline for this course, we had many options in mind for this tango session. However, we have decided that we will make this session as lively as possible while keeping it natural at the same time. We know our flow and we know our conversation highlight, but we do not know what exactly each of us is going to present. We have decided to challenge each other on stage and push each other’s knowledge to the verge. We promise that the session will be entertaining with lots of SQL Server trivia, tips and tricks. Here are the challenges that I’ll take on: I will puzzle Vinod with my difficult questions I will present such misconception that Vinod will have no resolution for it. I need your help.  Will you help me stump Vinod? If yes, come and attend our session and join me to prove that together we are superior (a friendly brain clash, but we must win!). SQL Server enthusiasts and SQL Server fans are going to have gala time at #TechEdIn as we have a very solid lineup of the speaker and extremely interesting sessions at TechEdIn. Read the complete blog post of Vinod. Session Details Title: SQL Server Misconceptions and Resolution – A Practical Perspective (Add to Calendar) Abstract: “Earth is flat”! – An ancient common misconception, which has been proven incorrect as we progressed in modern times. In this session we will see various database misconceptions prevailing and their resolution with the aid of the demos. In this unique session audience will be part of the conversation and resolution. Date and Time: March 21, 2012, 15:15 to 16:15 Location: Hotel Lalit Ashok - Kumara Krupa High Grounds, Bengaluru – 560001, Karnataka, India. Add to Calendar Please submit your questions in the comments area and I will be for sure discussing them during my session. If I pick your question to discuss during my session, here is your gift I commit right now – SQL Server Interview Questions and Answers Book.

• SQL SERVER – A Puzzle – Swap Value of Column Without Case Statement

  - by pinaldave

  For the last few weeks, I have been doing Friday Puzzles and I am really loving it. Yesterday I received a very interesting question by Navneet Chaurasia on Facebook Page. He was asked this question in one of the interview questions for job. Please read the original thread for a complete idea of the conversation. I am presenting the same question here. Puzzle Let us assume there is a single column in the table called Gender. The challenge is to write a single update statement which will flip or swap the value in the column. For example if the value in the gender column is ‘male’ swap it with ‘female’ and if the value is ‘female’ swap it with ‘male’. Here is the quick setup script for the puzzle. USE tempdb GO CREATE TABLE SimpleTable (ID INT, Gender VARCHAR(10)) GO INSERT INTO SimpleTable (ID, Gender) SELECT 1, 'female' UNION ALL SELECT 2, 'male' UNION ALL SELECT 3, 'male' GO SELECT * FROM SimpleTable GO The above query will return following result set. The puzzle was to write a single update column which will generate following result set. There are multiple answers to this simple puzzle. Let me show you three different ways. I am assuming that the column will have either value ‘male’ or ‘female’ only. Method 1: Using CASE Statement I believe this is going to be the most popular solution as we are all familiar with CASE Statement. UPDATE SimpleTable SET Gender = CASE Gender WHEN 'male' THEN 'female' ELSE 'male' END GO SELECT * FROM SimpleTable GO Method 2: Using REPLACE  Function I totally understand it is the not cleanest solution but it will for sure work in giving situation. UPDATE SimpleTable SET Gender = REPLACE(('fe'+Gender),'fefe','') GO SELECT * FROM SimpleTable GO Method 3: Using IIF in SQL Server 2012 If you are using SQL Server 2012 you can use IIF and get the same effect as CASE statement. UPDATE SimpleTable SET Gender = IIF(Gender = 'male', 'female', 'male') GO SELECT * FROM SimpleTable GO You can read my article series on SQL Server 2012 various functions over here. SQL SERVER – Denali – Logical Function – IIF() – A Quick Introduction SQL SERVER – Detecting Leap Year in T-SQL using SQL Server 2012 – IIF, EOMONTH and CONCAT Function Let us clean up. DROP TABLE SimpleTable GO Question to you: I came up with three simple tricks where there is a single UPDATE statement which swaps the values in the column. Do you know any other simple trick? If yes, please post here in the comments. I will pick two random winners from all the valid answers. Winners will get 1) Print Copy of SQL Server Interview Questions and Answers 2) Free Learning Code for Online Video Courses I will announce the winners on coming Monday.

• How to ace Skype Interviews

  - by FelixWehmeyer

  Many companies these days opt to include a Skype interview in the recruitment process, as it comes close to a face-to-face interview without the time and costs involved for both the company and the candidate. In some cases during the recruitment process at Oracle you also might be asked to conduct a Skype interview. To help you get started with this, we researched some websites to give you several tips and tricks. What most of the bloggers say about this topic is collected in this article to help you prepare. It is all about Technology The bit that can make a Skype interview more complicated than a face-to-face or phone interview is the fact you are using additional technology. Always check the video and audio capabilities of your computer to make sure they work properly. Be prepared for connections to be limited during the interview. Using a webcam can also be confusing, if you do not have a lot of experience using it. Make sure you look at the camera and not the monitor to avoid the impression you are looking away. Practice If you do not feel comfortable using the camera, do a mock interview with a friend or family member before you have the actual interview. Be aware that facial impressions or reactions come across differently on a monitor, so make sure to practice how you  come across during the interview. Good lighting in the room also helps you make you look the best for the interviewer. You and your room Dress code, as in any face-to-face interview,is important to think about. Dress the same way as you would for face-to-face interviews and avoid patterns or informal clothing. Another tip,is to be aware of your surroundings. Make sure the room you use looks good on camera, making sure it is neat and tidy, also think about how the walls look behind you. Also make sure you do not get distracted during the interview by anyone or anything, as this will directly have an impact on your interview and your ability to focus and concentrate. What is in a name What goes for any account that you share during the recruitment process, either your email address or Skype name, is to make sure it comes across as professional. Try to avoid using nicknames or strange words in your accounts, stick to using a first name – last name or an abbreviation of the same. If you would like to read more about this topic, have a look at the links below which we used as inspiration for this blog article. 7 Deadly Skype Interview Sins is fun to read and to gives you some good advice to keep in mind. ·         http://www.inc.com/guides/201103/4-tips-for-conducting-a-job-interview-using-skype.html ·         http://blog.simplyhired.com/2012/05/5-tips-to-a-great-skype-interview.html ·         http://www.cnn.com/2011/LIVING/07/11/skype.interview.tips.cb/index.html http://www.ehow.com/how_5648281_prepare-skype-interview.html

• Any tips on getting hired as a software project manager straight out of college?

  - by MHarrison

  I graduated with a BS in compsci last September, and I've been trying (unsuccessfully) to find a job as a project manager ever since. I fell in love with software engineering (the formal practice behind it all, not just coding) in school, and I've dedicated the last 3-4 years of my life to learning everything I can about project management and gaining experience. I've managed several projects (with teams around 12 people) while in school, and I worked with my university's software engineering research lab. My résumé is also decent - I worked as a programmer before I went to school (I'm 27 now), and I did Google Summer of Code for 3 summers. I also have general "people management" experience via working as the photo editor for my university's newspaper for 2 years. My first problem with the job hunt is not getting enough interviews. I use careers.stackoverflow.com, which is awesome because I usually get contacted by non-HR people who know what they're talking about, but there's just not enough companies using it for me to get interviews on a regular basis. I've also tried sites like monster.com, and in a fit of desperation, I sent out no less than 60 applications to project management positions. I've gotten 3 automated rejection letters and that's it. At least careers.stackoverflow gets me a phone interview with 8/10 places I apply to. But the main (and extremely frustrating) problem is the matter of experience. I've successfully managed projects from start to finish (in my software engineering classes we had real customers come in with a real software need and we built it for them), but I've never had to deal with budgets and money (I know this is why HR people immediately turn me away). Most of these positions require 5+ years PM experience, and I've seen absurd things like 12+ years required. Interviews are also maddening. I've had so many places who absolutely loved me and I made it to the final round of interviews, and I left thinking things went extremely well and they'd consider me. However, when I check in with them a week later, they tell me "We really liked you and your qualifications are excellent, but we're hoping to find someone with more experience." The bad interviews I can understand - like the PM position that would have had me managing developers both locally and overseas - I had 3 interviews with them and the ENTIRE interview process was them asking me CS brainteasers and having me waste time on things like writing quicksort on paper or writing binary search trees. Even when I tried steering the discussion towards more relevant PM stuff, they gave me some vague generic replies and went back to the "We want to be Google/MS" crap. But when I have a GOOD interview, they say my "qualifications are excellent" but they want "more experience"...that makes me want to tear my hair out. What else can I DO? While I'm aiming for technically-involved PM positions (not just crunching budget numbers), I really don't want a straight development job because I like creating software from the very high-level vs. spending a lot of time debugging memory leaks. In fact, I can't even GET development positions that I'm qualified for because I make the mistake of telling them that my future career goals are as PM (which usually results in them saying something like "Well we already have PMs and this position isn't really set up to get you there." - which I take to mean "No, that's my job, stay away.") My apologies on the long rant, but I'm seriously hellbent on getting hired as a PM since it's both my career goal and the passion that keeps me awake at night. Any suggestions on what the heck else I can do? I'm currently writing a blog where I talk about my philosophies about software engineering, and I'm writing up specs for an iOS app which I will design, code, and show employers, but this takes an awful lot of time that I don't have.

• How do you avoid jumping to a solution when under pressure? [closed]

  - by GlenPeterson

  When under a particularly strict programming deadline (like an hour), if I panic at all, my tendency is to jump into coding without a real plan and hope I figure it out as I go along. Given enough time, this can work, but in an interview it's been pretty unsuccessful, if not downright counter-productive. I'm not always comfortable sitting there thinking while the clock ticks away. Is there a checklist or are there techniques to recognize when you understand the problem well enough to start coding? Maybe don't touch the keyboard for the first 5-10 minutes of the problem? At what point do you give up and code a brute-force solution with the hope of reasoning out a better solution later? A related follow-up question might be, "How do you ensure that you are solving the right problem?" Or "When is it most productive to think and design more vs. code some experiments to and figure out the design later?" EDIT: One close vote already, but I'm not sure why. I wrote this in the first person, but I doubt I'm the only programmer to ever choke in an interview. Here is a list of techniques for taking a math test and another for taking an oral exam. Maybe I'm not expressing myself well, but I'm asking if there is a similar list of techniques for handling a programming problem under pressure?

• How to avoid to be employed by companies which are candidates to DailyWTF stories?

  - by MainMa

  I'm reading The Daily WTF archives and especially those stories about IT-related companies which have a completely wrong approach of software development, the job of a developer, etc. Some stories are totally horrible: a company don't have a local network for security reasons, another one has a source control server which can only be accessed by the manager, etc. Add to it all those stories about managers who don't know anything about their work and make stupid decisions without listening to anybody. The thing is that I don't see how to know if you will be employed by such company during an interview. Of course, sometimes, an interviewer tells weird things which gives you an idea that something goes very wrong with the company (in my case, the last manager said I should work 100% of my time through Remote Desktop, connected to on an old and slooooow machine, because "it avoids several people to modify the same source code"; maybe I should explain him what SVN is). But in most cases, you will be unable to get enough information during the interview to get the exact image of a company. So how to avoid being employed by this sort of companies? I thought about asking to see some documents like documentation guide or code style guidelines. The problem is that I live in France, and here, most of the companies don't have those documents at all, and in the rare cases where those documents exist, they are outdated, poorly written, never used, or do force you to make things that don't make any sense. I also thought about asking to see how programmers actually work. But seeing that they have dual screens or "late-modern-artsy-fartsy furnishings" doesn't mean that they don't have people making weird decisions, making it impossible to work there. Have you been in such situations? What have you tried? Have it worked?

There were also some really good tips at Is thinking out loud during an interview really the best strategy?. A great and concise argument for TDD is the first answer to TDD Writing code vs Figuring out the answer to a problem?. My question may be a near-duplicate of that one.

• Need Directions to become a programmer [closed]

  - by Omin

  Before youguys go on about how there are many types of programmers, please read through the post. Long term goal: Develop my own software (company) Short term goal: Get a job that involves coding/programming Current status: Support Analyst (at a software company but does not involve any programming) with 40k salary, 3rd year computer engineering student I had everything figured out. I'm going to develop a 2D scrolling game for iphone or android, publish the app, sell a bunch, and then apply at a studios as a software developer. And then something hit me. I think I need to get a job that involes programming to learn as much as I can in the shortest time possible. So I got a phone interview at a fast growing start up software company, passed that no problem, but then had to take an online technical assessment. That failed miserably. I thought that if I could just present myself, show that I am hard working, positive attitude, eager to make self improvements, type of a guy, I could get the job. I was wrong. And now, I am lost. Im thinking of staying with my job until I find a new one as a programmer. I will be working, self studying, and trying to make this happen without finishing university. I forgot to mention that the online technical assessment was based on data structures/algorithms, OO design, runtime complexity. I was hoping that I could get some guidence. Should I be focusing on app development or study computer science fundamentals? I have a list of books I can be going through: Learning C# O'Reilly (I got interested in C# because of Unity3D and Mono), C# 5.0 in a Nutshell, Head First Design Patterns, Code Complete, Introduction to Algorithms, Programming Interviews Exposed, Cracking the Coding Interview, The Google Resume.

• Can an Employer turn you down if you have said the fact about current work culture being bad [closed]

  - by MansonRix

  I had recently an interview where I scored good in 1st two round of technical interview . Then in the 3rd round was the managerial round where the guy started about my experience and whether I have vaptured any requirement and handled and trained any teams. This went pretty well for around 50 mins . Then there was the awkward question , Interviewer: why amI looking for a change? Me: coz I want to explore my carrier options? Interviewer: But your current company is big enough and you can explore options over there? (This was supposedly the trap) Me: Apart from that I am missing the flexibilty of working with Us and Europe based company as my current company is not that flexible. Interviewer: What exactly you don't find flexible. Me: The login time . Even if you get late by 1sec you might have to explin. Though this is not a big problem , still I will prefer flexibilty as we are working really hard. Interviewer: Allright ( Then couple of more questions) , Hope to C U Ya , that's pretty much it . Now I called up HR and they say , they are yet to get the feedback from Interviewer. Did I screw it? I mean does some one really have to pretend always by saying positive things about company and manager though not saying negative things?

• Check my anagram code from a job interview in the past.

  - by Michael Dorgan

  Had the following as an interview question a while ago and choked so bad on basic syntax that I failed to advance (once the adrenalin kicks in, coding goes out the window.) Given a list of string, return a list of sets of strings that are anagrams of the input set. i.e. "dog","god", "foo" should return {"dog","god"}. Afterward, I created the code on my own as a sanity check and it's been around now for a bit. I'd welcome input on it to see if I missed anything or if I could have done it much more efficiently. Take it as a chance to improve myself and learn other techniques: void Anagram::doWork(list input, list &output) { typedef list SortType; SortType sortedInput; // sort each string and pair it with the original for(list<string>::iterator i = input.begin(); i != input.end(); ++i) { string tempString(*i); std::sort(tempString.begin(), tempString.end()); sortedInput.push_back(make_pair(*i, tempString)); } // Now step through the new sorted list for(SortType::iterator i = sortedInput.begin(); i != sortedInput.end();) { set<string> newSet; // Assume (hope) we have a match and pre-add the first. newSet.insert(i->first); // Set the secondary iterator one past the outside to prevent // matching the original SortType::iterator j = i; ++j; while(j != sortedInput.end()) { if(i->second == j->second) { // If the string matches, add it to the set and remove it // so that future searches need not worry about it newSet.insert(j->first); j = sortedInput.erase(j); } else { // else, next element ++j; } } // If size is bigger than our original push, we have a match - save it to the output if(newSet.size() > 1) { output.push_back(newSet); } // erase this element and update the iterator i = sortedInput.erase(i); } }

• Resources and techniques/methods for SCJP preparation ?

  - by BenoitParis

  I am passing the SCJP 6 exam in a month. I have the "SCJP Sun Certified Programmer for Java 6 Exam 310-065" book. It seems great for the exam. But I want your advice on this. Getting the closest possible to 100% would be great. I have found a site that answered some of the questions you ask yourself when you go trough the book. Here is it : http://www.janeg.ca/java2.html As you can see it was written for Java 2 :/ I have written another specific question here on StackOverflow about the usefulness of JVM specification and Java compiler code for the SCJP. Will Update the results here. Here it is. Please share the resources you used in preparing the exam. Please also specify any resources that you think might help. Any type of resource is welcome: books, code, specs, sites, wikies, papers, online tests, grandmas... Please also share on any method/technique that helped you prepare the exam. Please also comment on the return you got from the resource and the method (for the learning process and for points in the exam) I'll begin: Book : "SCJP Sun Certified Programmer for Java 6 Exam 310-065". Seems like the official book for the preparation. Technique : Writing code in a text editor and compiling it with javac to test a question. NO IDEs! It helps you get a a straight answer to a question you have. It helps you pay attention to every word in the code (and this is very important in the SCJP) EDIT: Added dimension: Are there good, up-to-date online tests?

• SQL SERVER – Monday Morning Puzzle – Query Returns Results Sometimes but Not Always

  - by pinaldave

  The amount of email I receive sometime it is impossible for me to answer every email. Nonetheless I try to answer pretty much every email I receive. However, quite often I receive such questions in email that I have no answer to them because either emails are not complete or they are out of my domain expertise. In recent times I received one email which had only one or two lines but indeed attracted my attention to it. The question was bit vague but it indeed made me think. The answer was not straightforward so I had to keep on writing the answer as I remember it. However, after writing the answer I do not feel satisfied. Let me put this question in front of you and see if we all can come up with a comprehensive answer. Question: I am beginner with SQL Server. I have one query, it sometime returns a result and sometime it does not return me the result. Where should I start looking for a solution and what kind of information I should send to you so you can help me with solving. I have no clue, please guide me. Well, if you read the question, it is indeed incomplete and it does not contain much of the information at all. I decided to help him and here is the answer, which I started to compose. Answer: As there are not much information in the original question, I am not confident what will solve your problem. However, here are the few things which you can try to look at and see if that solves your problem. Check parameter which is passed to the query. Is the parameter changing at various executions? Check connection string – is there some kind of logic around it? Do you have a non-deterministic component in your query logic? (In other words – does your result is based on current date time or any other time based function?) Are you facing time out while running your query? Is there any error in error log? What is the business logic in your query? Do you have all the valid permissions to all the objects used in the query? Are permissions changing or query accessing a different object in various executions? (Add your suggestions here) Meanwhile, have you ever faced this situation? If yes, do share your experience in the comment area. I will send a copy of my book SQL Server Interview Questions and Answers to one of the most interesting comment. The winner will be announced by next Monday.  Reference: Pinal Dave (http://blog.sqlauthority.com) Filed under: PostADay, SQL, SQL Authority, SQL Interview Questions and Answers, SQL Puzzle, SQL Query, SQL Server, SQL Tips and Tricks, T SQL, Technology

• Studying computer science - what am I getting myself into?

  - by clankercrusher

  I'm a student considering the possibility of studying computer science. I've picked up programming indie games and websites as a hobby and I really enjoy it. Despite my fairly positive experience, I somehow get the feeling that computer science in the business world will be completely different than do-it-for-fun game making. Since I'm interested in the field and I'd like to study well, I want to prepare myself for the onslaught. (If that’s even possible) What are some of the most important principals I need to know if I decide to study computer science? What will I need to know about computer science that a University probably won't teach me? Is there any way I can get hands on experience before or while I'm at a University? What am I getting myself into? P.S. Is this the right stack exchange site for this type of question?

• Do other developers feel that as they get better, it becomes harder to get jobs?

  - by nbv4

  When I was starting out, it seemed I had a much better time getting interviews and passing them. But now that I'm more experienced, I'm finding that its harder and harder to find a job. Do other developers out there feel the same way? I'll give you an example. I did an interview last Wednesday. It was a small start-up with only one other engineer and the CEO. They flew me in from Ohio (they are SF based). When I got there, they had me write them a link shortener, which took me about 10 minutes to write. I was supposed to be there all day working on this. When I finished it early, the interviewer seemed kind of shocked. After that, we were talking, and I asked him what they use to store data. He told me Mongo. I ask why he decided to use mongo. He then stammered and mumbled his answer, which basically boiled down to "We're using it because Mongo is a the trendy database technology and we don't want to be left out", which I've found is pretty much most common reason people use NoSQL these days. The interviewer quickly ended the interview and pretty much shoved me out the door. I was supposed to have lunch with the CEO, but I he kicked me out before I had a chance. The intervier wasn't mean or rude, (and neither was I). After I got back to Ohio, I got an email from them saying "I wasn't a fit". This sot of thing happens to me all the time. I'm starting to think "not a fit" can sometimes mean "are too high of a skill level that we are". Is this all in my head, or do other experienced developers notice the same thing happening? Back when I used to struggle with coding problems, I would work with the interviewer and it would be a positive thing and I'd get hired. But now I usually blow through the coding part, and the interviewer being left speechless is working against me. Should I feign struggling with coding problems?

• Is it a bad idea to ask an interviewer what the greatest strength and weakness of their development team is?

  - by epignosisx

  I was wondering if this was a good question to ask a possible employer when interviewing for a developer position: What is the greatest strength and weakness of your development team? We all get this question when we are in an interview, so why not ask them in return? I think it is a very good question because we could find out about the team, and how this strength or weakness could affect us, but I don't want to annoy the interviewer. Is there any downside to asking this question when interviewing for a developer position?

• What's your advice in getting Oracle Certified Professional Java Programmer certificate?

  - by den-javamaniac

  Hi. I'm intending to get the certification but not completely sure how to time effectively prepare myself. So I'm wondering if I can be advised on the matter, in particular I would like next questions to be answered: - What the basic learning/practicing plan should look like? - What book (set of books) should be considered? - What practical exercises should be performed? NOTE: I've got several years of corporate experience (mostly web apps, though), but I want to be 100% sure I'll pass the test (that's the reason the issue is raised).

  Devise a simple algorithm which creates a file which contains nothing but its own checksum. Let's say it is CRC-32.

• How does someone without a CS degree get an interview in a sluggish economy?

  - by Anon

  I've been programming off and on since 4th grade (for about 20 years). Technology is one of my passions but after working in the field for a couple years out of High School, I spent nine months and $15,000 getting an accredited certificate in music performance instead of CS. I've been doing lots of self study but I think a CS degree is overkill for most line of business applications. Even so, HR departments can't be expected to know that... How does one get their foot in the proverbial door without a degree, especially in a smaller "fly-over country" market? ...or... Where can I get the cheapest/easiest degree that will pass muster (including testing out of as much as possible)? Don't get me wrong, I'm down with learning new things but I don't necessarily need the expense or coaching to motivate me. EDIT Consolidating good answers: Networking/User Groups Portfolio/Open Source Contributions Look for hybrid jobs (How I got my start :) ) Seek un-elitist companies/hiring managers. (Play the numbers game) Start my own business. (This is a bit challenging for a family man but a very good answer. My reason for searching is to reduce my commute thereby allowing more time to cultivate income on the side) Avail myself of political subsidies to constituents in the teachers' unions ;) .
