Brought in dozens of candidates, quick presentation, and then a series of interviews in large rooms with other candidates. Talked to one engineer for behavioral interview (who admitted he didn't know how to conduct a behavioral interview so we just walked about my resume) and another for a technical interview (who played dumb with every solution I gave him only to admit at the end that he was jerking me around to see what I said, and that I had the best solutions he'd seen that day). Fed us lunch and then sent us back to the airport.

I don't think this will work, what is wrong with your solution?
