I once went for an interview were the interviewer was the
one who wasn't comfortable to speak (he was a techie as well,
and assigned to do the interview because he happened to visit
a customer in Amsterdam, and that was cheaper than to fly me
to London). The whole interview lasted 10 minutes, and that
included ordering coffee. I remember the one technical question: Suppose someone comes to you saying they can't
telnet to a certain box, what do you do?
. To which I answered I'd go over and read the error message
I got the job.
