Okay, it's been awhile for me, but it was one on two with a chief piltot and a lady from HR. They asked me a bit about the aircraft I was flying, and some technical questions. It was pretty easy, as the Chief pilot asked me first, how much does your current aircraft weigh? I said 45,000 lbs, and after that it seemed pretty easy.
If you are asking about the tech eval, I hear it has changed a bunch since I did it. Now they use the same light pen test that Delta uses. I would recommend Air Inc for their gouge, as they helped me a lot when I did it. Good luck to you.
