Anyway, the interview was most unusual. After the interviewer introduced himself and described his group a bit, I pretty much did all the talking. I asked lots of questions about the group, its relation to other groups, the types of projects people work on, etc. Turns out this is a business operations group similar to the one I was in.
The interview lasted about a half hour, but within the first five minutes, I pretty much figured out everything I needed to know. Without going into a lot of details, should I be offered (and accept) a position with this group, I will effectively be signing up for the same type of experience I had at AV the last four years.
