One phone screen. Very confusing question. I pointed out that it didn't actually make sense, so the interviewer changed it on the fly. I couldn't get the answer, so the interviewer just told me. They should really just stick to standard data structure and algorithm questions. I think I only got the offer because of a project I had on my resume.

Questions about resume. Technical question was, given a stream of incoming tweets and a machine that can only store one tweet at a time, how would you make a function that randomly selects (from all tweets that have come in) a tweet to store?
