This is a list of interview questions for technical people that I've come across. I always appreciate contributions.
You'll probably note that I don't provide answers, like most interview questions lists do. This is on purpose: I'm of the opinion that if you can't answer (most of) the questions yourself, you should probably draft a friend/colleague for the technical portion of the interview.
With the exception of the Microsoft Brain Teasers page and some of the Traditional Interview questions, these are all original questions that I've written. If you're an hiring manager, hopefully you'll use this list to inspire you in coming up with your own questions.
