Lord almighty, that's a hard one. I was recently interviewed for a .NET programmer (something I know little off) and there was a 1/2 hour exam with questions on programming ("What is polymorphism?") SQL ("What is a subquery?") and web design ("What is CSS and what is it used for?"). Was pretty easy but I got some questions wrong.

Then in the interview they asked a series of "problem solving" questions, one of which was "How would you write a system that had a web interface and could sychronously communicate between two servers". That lost me, but I made up something.

Anyhow I got the job, so . Think of it this way: if they're cruel enough to set that as a question, would you like to work for them?
