I was contacted via email on a monday, after an exchange of emails on that day we made an appointment for a phone interview on that wednesday at 11am. 10 minutes before he was supposed to call he emailed me saying he was sick and we should reschedule for that friday for the same time. Come Friday, he never called, or responded to any of my emails over the next week. Very unprofessional. I applied again to the same job and spoke to a different recruiter over the phone (with no notice) and was given an over the phone interview, afterwards he asked me to speak to me in person a week later. The in person interview was me, and three employees asking me questions.

Casual, hands-on, and fun! This was a very low-pressure panel interview with 3-4 other folks asking a mix of situational and technical questions. You are told from the very beginning that there are no wrong answers, to be calm and honest, and that they're simply trying to gauge what you know and what type of person you are. Half of the interview is the traditional FAQ type stuff, while the other half is hands-on drawing stuff out on a white board and troubleshooting various scenarios.
