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.
