Wow...all with the same group or was it multiple meetings?
Multiple meetings in half hour increments!! But now after all that I have reservations about the position.
Reservations because of the interview process?
I ask because I had something very similar (for the good bonus place! for my final interview. It was 4 30 minute meetings with individuals and one hour long one with multiple people. I was exhausted, but depending on the level of responsibility, I think they are just doing their due diligence. I wouldn't discount the job over that.
If you have reservations about things you learned during the interviews, that's totally different.
