I've gotten feedback when I interviewed on why they did not extend an offer. Its emotionally difficult when interviewing to put yourself out there, but getting feedback does help you understand how the interview went down better.
Facebook is great about this, but they shattered industry norms with their practice. It is one of the classiest ways they exemplify their top to bottom belief in sharing information with everyone, in product and in corporate.
What are you talking about? I did a phone interview and two on-site interviews, and the only feedback I got was a generic form letter that my background was not the right fit, which clearly isn't the whole story because there's no need to pay for a plane ride if my resume isn't what you're looking for. I'm guessing either they've changed policy here or you or someone you know happened to get a nice interviewer.
What are you referring to? The first time I interviewed there, I got zero feedback. The second time, I didn't make it past the phone screen (which has never happened to me before so I thought it was remarkable/funny.) and got the old "didn't think was a good fit" line.
