Ask HN: Do you ask for feedback on job interview?

I always ask for feedback. Some of it wouldn't be useful due to the fact that each company is different. However feedback on communication, presentation, and in some cases technical performance can be useful ways to calibrate for future interviews.

I've got feedback twice out of the last dozen interviews I've been on.

I've solicited feedback a few times but never actually got any. Either just didn't hear back, or was told that they were unable to provide any. Which didn't really surprise me.
