This started off as a great interview and tour of the facility but after almost 7 full hours of meeting people, interviews with various dept heads and a final test, I was spent. No offer of lunch and I finally asked for a bottle of water at about 4:30. I have had lengthy interviews before but no-one seemed to know what I had done with the person before them. By the final test at the end where I listened to a tape recording and filled in written questions, I simply wanted to be done and gone.
