NewYork-Presbyterian Hospital interview questions

First I got a call from HR and he asked me a few questions about myself and a couple of situational questions and was pretty casual. Then second round with another HR member who also asked situational questions and was very pleasant. However, I next spoke with the Chief PA who I found to be rude and not conversational. She also asked me situational questions, and at that point I had been asked so many it was difficult to continue to come up with other experiences to share that I had not already discussed.
