Getting Feedback from the Interviewer

Dear Experts, I had a series of interviews last week with a few different companies. I don't think any of the interviews will lead to any job offers but I am curious how I presented myself when I met each hiring manager. Is there a proper process for obtaining feedback on my interview skills from the interviewer? Our Twitter Advice Project (T.A.P.) is no longer an active campaign.
