AOL Project Management interview questions

The phone interview with HR went very well. The person was polite, professional, and asked the right questions. I then had another phone interview with the hiring manager. That interviewer was professional and respectful and asked questions relevant to the position. But when I went for an in-person interview, which consisted of 4 sequential interviews, each interviewer was worse than the last. The 4th was an engineer who seemed intent on treating me in a way which was both degrading and insulting. I was put off with myself for even staying through this disrespectful process. I was asked questions completely outside the realm of the position for which I was interviewing. HR was aware that the candidates were being mistreated, but seemed unable to put a stop to it.
