    For the last two hires I had, I threw together a few questions about Perl to smoke out anyone who obviously had never done anything with the language.

    What are the differences between C<our>, C<my> and C<local>?

    What is C<$!>?

    What is C<$_>?

    What is C<$&>?

    What is C<$1>?

    How do you delete a file?

    What does C<TMTOWTDI> mean?

    How do you implement a list of hashes?

    I figure that someone who's been using Perl for a while will know all these. I don't like memo

      Once upon a time I went for interview with Overall I'd have to say I didn't like the location or the atmosphere, and I was glad I didn't get the job, however the random test at the interview was actually quite good.

      Without any warning the sat me down with a glass of water, a pencil and a sheet of awful HTML and asked me to fix it. At once I said it was not possible without knowing the DTD I was correcting it too, they said "current", and left me to it. I know I scored well they told me so when the rejected me! I've always like the idea of a random simple test at interview ever since.

      I liked:

      • Random nature - you don't worry in advance.
      • No tools to rely on - what you have in your head is all you get.
      • Open-ended, they said put as many comments as you like on the page.
      • Tests work under stress.

      I know that tests are very artificial, and mostly test people's ability to do tests, but a short random test has some uses as part of an overall process.

      As we are looking for a Perl/Web person at the moment [], I think I'll have to come up with a few quick questions of my own. I hope you don't mind me borrowing yours?
