Bother them or not?
ismarc: I would suggest a follow-up email.  I always remember the answer to a question, or realize a bug in some whiteboarded code, etc.  It's also polite to thank them for their time...interviewing someone took time out of their day.  I typically do it within 1-2 weeks and try to work in something that likely would be memorable from the interview (not a "remember me, I was the guy whose battery died" and more "since that blunder of my laptop dying during the interview, I've started carrying a spare battery!").  There's no feeling of obligation for them to respond, but puts you back in the forefront of their mind, shares some more of your personality and can lead to a follow-up interview/discussion.That being said, I've only had one interview not result in a job offer of some sort (I've had some offers for contract work where I didn't get the full-time offer I consider successes) and I'm confident that had I been local and done an in-person interview I would have done much better (was my first remote/on the phone interview, and I imagine it must have been painful for the interviewer).  When interviewing people, if they were good, I'm elated to see the follow-up.  If they weren't, I dread it since it means I really need to start writing up rejection responses.  What's the worst that'll happen, not getting the job?
