I hate interviews. I hate being the one interviewed, I hate being the one interviewing. Now that I am with a company that is actually hiring and not laying off, I am getting to interview people more often. Yesterday, I had an interview with a guy who put on his resume that he knew PHP, Perl, Unix and some other stuff. So, I wanted to find a way to test his knowledge. I came up with this simple, yet oh so deceptive question... Tell me what this Perl script will output:
$a = 20;
$b = 4;
$q = $a + $b;
$r = $a - $b;
$s = $a / $b;
$t = $a x $b;
print $q,$r,$s,$t;
