I am in charge of selecting a new software development intern for a company that I work with. I wanted to throw a little 'quiz' at the applicants before moving forth with interviews so as to weed out the group a little bit to find some people that can demonstrate some skill. I put together the following quiz to send to applicants, it focuses only on PHP, but that is because that is what about 95% of the work will be done in. I'm hoping to get some feedback on A. if its a good idea to send this to applicants and B. if it can be improved upon.

# 1. FizzBuzz
# Write a small application that does the following:
#   Counts from 1 to 100
#   For multiples of 3 output "Fizz"
#   For multiples of 5 output "Buzz"
#   For multiples of 3 and 5 output "FizzBuzz"
#   For numbers that are not multiples of 3 nor 5 output the number.

?>

# 2. Arrays
# Create a multi-dimensional array that contains
# keys for 'id', 'lot', 'car_model', 'color', 'price'.
# Insert three sets of data into the array.

<?php



?>

# 3. Comparisons
# Without executing the code, tell if the expressions
# below will return true or false.

<?php

    if ((strpos("a","abcdefg")) == TRUE) echo "True";
    else echo "False";
    //True or False?

    if ((012 / 4) == 3) echo "True";
    else echo "False";
    //True or False?

    if (strcasecmp("abc","ABC") == 0) echo "True";
    else echo "False";
    //True or False?

?>

# 4. Bug Checking
# The code below is flawed. Fix it so that the code
# runs properly without producing any Errors, Warnings
# or Notices, and returns the proper value.

<?php

    //Determine how many parts are needed to create a 3D pyramid.
    function find_3d_pyramid($rows) {
        //Loop through each row.
        for ($i = 0; $i < $rows; $i++) {
            $lastRow++;
            //Append the latest row to the running total.
            $total = $total + (pow($lastRow,3));
        }
        //Return the total.
        return $total;
    }

    $i = 3;
    echo "A pyramid consisting of $i rows will have a total of ".find_3d_pyramid($i)." pieces.";

?>

# 5. Quick Examples
# Create a small example to complete the task
# for each of the following problems.
#   Create an md5 hash of "Hello World";
#   Replace all occurances of "_" with "-" in the string "Welcome_to_the_universe."
#   Get the current date and time, in the following format, YYYY/MM/DD HH:MM:SS AM/PM
#   Find the sum, average, and median of the following set of numbers. 1, 3, 5, 6, 7, 9, 10.
#   Randomly roll a six-sided die 5 times. Store the 5 rolls into an array.
