Columbus Technical College interview questions

panel interview followed by individual interview with President of Company(for all full-time positions). Panel interview went fine from my thoughts and feedback. Individual interview, I was a little nervous; however, I felt the interview process was fine. I asked for feedback after interview and received none. I felt this was not professional b/c I personally asked for feedback due to the fact that I didn't receive position. I wanted this feedback for future interviews; so that I may work on what was wrong.
