Lion Group interview questions

I met with the hiring manager, did a site tour, and met with several employees. The interview was about an hour long. I got some standard interview questions, did a little "get to know you" discussion, and then had a discussion based on questions I asked. Overall it was a good interview process on site and in person. After the in person interview, there was a delay from the HR department. I found out later that HR was not communicating well with the hiring manager and I had to do a phone screen with HR again.

I was told to come in to speak with HR about my resume and was told specifically that they had no positions open it was NOT an interview. They just wanted to ask me to clarify a few things. I arrived 10 min early and was kept waiting for a half hour. When I was invited into the room, it was a three person panel interview! Total stress interview. One person made it his aim to find fault with whatever I said, while the others were neutral at best.
