Interview within two days of initial notice. About 20 minute phone interview with several people on the line. Talked a lot about previous experience (albeit unrelated to the job I was applying for) and some future aspirations and things like that. Just tried to be relaxed, honest, and friendly and I'm glad it worked out; I was given an offer about a week or two later.

I got an email for a phone interview so long after applying that I forgot even applying in the first place. Then nothing for months then another phone interview asking the same behavior/situational questions as the first phone interview. Another month then a call for an onsite interview. I was used to one-on-one interview. This turned out to be a mass interview. I was part of a group of about half-a-dozen interviewees vying for about a dozen open positions. I was part of the third and last group interviewed. Everyone interviewed with two panels of two people. The questions were mostly situational, i.e. Have you ever been in this situation, if so what did you do? Very few technical questions about my knowledge, skills or experiences. I am more used to technical questions, i.e. how do you make such-and-such compound?
