Columbia University interview questions

I saw the job posting, I arranged my schedule. We went through my resume. They asked me questions. They asked me technical questions. They asked me questions regarding my future. I answered everything and then they told that they would call me. But they never called back.

I applied to this position online after hearing of it through a referral. It had been vacant for months and still is vacant three and a half months later. I found the whole process very slow and disappointing. It took about six weeks for them to call. I had a short phone interview the following day with the executive director of HR. She told me someone from the business school would call me to set up in person interviews. I interviewed in person about two weeks later. First, I met with the assistant director of HR who was pleasant. She asked me several of the typical questions and many about supervising others. Then I met with the senior associate dean of the business school who was very nice. That interview was very short and the easiest of the three. Next was the executive director of financial planning who was the toughest. It was very hard to read her. All three interviews combined took a little over an hour. I sent thank you emails to all three and received no response. I also sent a follow up email to the HR asst director I met with which also went unanswered. I found the lack of feedback or follow up to be very unprofessional. The campus was beautiful. I think salary was one issue against me. It doesn't seem that they pay very well.
