  • Must have JavaScript pro developer tools, libs, utilities and workshop configuration.

    - by WooYek
    This is a followup question to the Pro JavaScript programmer interview questions (with answers). What is considered professional and industrial standard for a professional browser side Java Script developer when it comes to his workshop configuration, and maybe from-concept-to-shipment process? What are the most popular IDE's, utilities and probably libraries, not limited to the free ones. These that can help cut development time (eg. IDE), help with achieve better quality (eg. unit testing tools), reliability and maintainability. I'm looking for a baseline to which I could compare potential candidates based on their ability to keep their tools sharp and workshop efficient (pro's should invest time&money in good tools, right?).

  • need thoughts on my interview question - .net, c#

    - by uno
    One of the questions I was asked was that I have a database table with following columns pid - unique identifier orderid - varchar(20) documentid - int documentpath - varchar(250) currentLocation - varchar(250) newlocation - varchar(250) status - varchar(15) I have to write a c# app to move the files from currentlocation to newlocation and update status column as either 'SUCCESS' or 'FAILURE'. This was my answer Create a List of all the records using linq Create a command object which would be perform moving files using foreach, invoke a delegate to move the files - use endinvoke to capture any exception and update the db accordingly I was told that command pattern and delegate did not fit the bill here - i was aksed to think and implement a more favorable GoF pattern. Not sure what they were looking for - In this day and age, do candidates keep a lot of info on head as one always has google to find any answer and come up with solution.

  • How long should it take a senior developer to solve FizzBuzz during an interview?

    - by Jim McKeeth
    Assuming: Typical interview stress levels (I am watching) Using familiar IDE and program language (their choice on their PC!) Given adequate explanation and immediate answers to questions Able to compile code and check answers / progress Claims to be a senior level programmer How long should it take an interviewee to answer FizzBuzz correctly? Edit: FizzBuzz: Write a program that prints the numbers from 1 to 100. But for multiples of three print "Fizz" instead of the number and for the multiples of five print "Buzz". For numbers which are multiples of both three and five print "FizzBuzz". Edit: It isn't so much that if they take more then X minutes they are disqualified, but I am curious if I should just cut them loose after they work on it for half hour.

  • Odd C interview question

    - by Brennan Vincent
    Hi guys. I found this problem on a site full of interview questions, and was stumped by it. Is there some preprocessor directive that allows one to read from standard input during compilation? Write a small C program, which while compiling takes another program from input terminal, and on running gives the result for the second program. (NOTE: The key is, think UNIX). Suppose, the program is 1.c Then, while compiling $ cc -o 1 1.c int main() { printf("Hello World\n"); } ^D $ ./1 Hello World

  • Is it possible to apply inheritance to a Singleton class?

    - by Bragaadeesh
    Hi, Today I faced one question in interview. Is it possible to apply inheritance concept on Singleton Classes. I said since the constructor is private, we cannot extend that Singleton class (can someone please validate this). Next thing he asked me is to apply inheritance on that Singleton class. So, I made the Singleton's constructor as protected thinking that child's constructor also has be protected. But I was wrong the child can have a modifier either equal to or higher than that. So, I asked him to give a real world example on such a case. He was not able to give me one and said that I cant ask questions and wanted me to tell whether this scenario is possible or not. I went kind of blank. My question here is, Is this possible? Even if its possible, what is the use of it? What real world scenario would demand such a use. Thanks

  • Is it acceptable to email an Interviewer after the interview?

    - by djhworld
    Yesterday I took part in an interview for a Java position in a company and one of the questions was Does Java pass by reference or by value? In the heat of the moment I (mistakenly) confidently said it passed by reference, possibly because I come from a C/C++ background. Unfortunately after the interview I'd realised my terrible mistake to my horror. So my question is this, is it acceptable for me to wait a few days and drop a quick email to recognise my mistake? Or should I just let this one lie?

  • How to serialize a graph ?

    - by Michael
    This is an interview question: How to serialize a graph ? I saw this answer but I am not sure if this is enough. It looks like a very confusing "open question" and the candidates are probably expected to ask more questions about the requirements: what the nodes and edges are, how they are serialized themselves, is this graph weighted, directed, etc., how many nodes/edges are in the graph.What about the infrastructure ? Is it a plain file system or we should/can use a database ? So, how would you answer this question ?

  • What should I ask a prospective client during initial meeting?

    - by Anna Lear
    I'm about to branch out into taking on some contracts on the side. What would be some good questions to ask of a potential client during a first meeting? I've thought of a few things that seem pretty obvious: * What is the project? * What are the deadlines? * What's the budget? * What/how do they want me to deliver the completed work? Is that it, or are there any tricky things to watch out for?

  • Best and shortest books on C++/STL/C#/J2SE to prepare for job inteview/tests

    - by Nerd
    I am a software developer with 10+ years commercial experience, I am comfortable with nearly all of imperative languages. But I realized that most of employers prefer not candidates who is able to deliver good software but those who is trained to answer questions like "what are ten differences between pointers and references in C++" or "what this messy code fragment will print". Last time I have read a book on C++ 15 years ago in secondary school and yes, that was Bjarne Stroustrup. But today I need something quick, without long philosophical explanations about polymorphism etc but with focus to silly interview tests. So, can you recommend any short and effective books to refresh my theoretical knowledge? Thank you.

  • Looking for a few good C# interview problems.

    - by AngryHacker
    I do not want to ask candidates questions, but rather give them several problems to resolve. The reason for this is that I've seen people be excellent with theory, but when confronted by a real world c# issue, just couldn't hack it. These c# problems should be simple enough that it won't take more than 5-20 minutes to resolve, yet complicated enough that I'd be able to weed out candidates that can't code. Right now, I typically ask the applications to reverse a string and remove duplicates from a List. This alone weeds out a large number of people. Any other examples I could use?

  • How to find the length of a linked list that is having cycles in it?

    - by Bragaadeesh
    This was one of the interview questions asked. How to find the length of a linked list that is having cycle in it. I know how to calculate whether a linked list has a cycle or not using Hare and Tortoise technique. I even know how to calculate the length by storing the addresses in a hashset. But what I was not able to tell is how to calculate the length of the linked list without using a external space of O(n). Please help me. Thanks.

  • Do you ask questions in real life like you do at SE.com?

    - by tactoth
    At this website I find amazing questions for programmers. Then I realized that I don't discuss these questions with my colleagues as often. You see, we're all programmers and we are supposed to have talked about these, (in a everyday conversation what we can talk would be more meaningful because it's faster) but we don't. So what about you? Do you enjoy discussing interesting programmer related topics with your programmer friends?

  • What are good technical questions to ask to determine the analytical skill of a programmer?

    - by ENT
    I am a non-technical recruiter and I want to lay out some initial interview questions, one of which is to determine the analytic skill of a person. We will soon launch our hiring process for programmers and we are mapping out what would be the best questions. I have read quite a few posts here that suggested on how to interview programmers but I haven't come across on what technical question to ask that non-technical recruiters can easily comprehend if the answer is good or bad.
