I believe it will be more along the lines of a 3rd and 4th interview, really. I understand that I am one of the final 3 candidates from a largish pool of applicants. The director of the department has been very thorough, having called 5 references and had fairly lengthy chats with them. I appreciate that attention to detail, and am also thankful for the feedback my references have given me on him. They all share my impression that he is a straight shooter. They've given me 'permission' to go work with him ;)
The story of the first interview is had a first interview about a week and a half ago. It was an interesting situation - I was expecting a 1st interview, but what occurred was much more along the lines of a 2nd. I knew I would be interviewing with 3 people (dept. manager + 2 team leads), but was not expecting the 7 pages of questions they had. I was a little surprised at that, which lead to me becoming a bit nervous and not being at my best for the first 30 - 40 minutes. I did bring things around and had some very good informational moments and a few moments of mutual levity, but wad disappointed I wasn't perfect, yanno. They had told me to expect about 60 - 90 minutes, but I was there with them for over 2 hours. I hoped that was a good sign.
I was pleasantly surprised, and very pleased to be asked back. Other reasons I felt the first interview wasn't my best were I was exhausted after being at the conference and vending for a week plus traveling the previous day and getting home late, combined with The Cold (the bad kind that makes your eyes & teeth hurt and leaves you in fear of drowning in your sleep). So I should already be better out of the gate on the 2nd.
This whole experience has made me feel better about my skills, experience, and abilities. Not to mention helping me to feel better about the interviewing process. It's not bad to make the final cut for a competitive and desirable position on my first interview in 2 1/2 years.
Hopefully there won't be another 35 questions ;) And no, I didn't try to memorize the Federal Acquisition Regulation in 4 days...
