Turned me down in 07' after a handful of phone interviews, flying me across the country, and 8 hours of in person interviews with 3 separate departments... but not before I got their CTO so shitfaced drunk he botched a 2AM code push to production and helped convince Zuckerbergs little sister into riding a mechanical bull.
I regret nothing.
edit: Worth noting I was a 22 year old self taught programmer that hadn't experienced addressing O(log n) in a CS course, working with massive amounts of data, or large scale Linux sysadmin stuff. I wasn't fit for the ranks when compared against ex Yahoo! and Google people running for the same positions. So at least I made the most of it.
edit2: I got the interview after finding a bug in their authentication system that would allow a password hash collision to spit out the e-mail of the user that the collision occurred with. Meaning I type in a bogus email, and a password, after the post the login form would come back with the email pre-populated of the user that the hash collision had happened on, I type in the password again, and I was logged in as said user. It was a small bug I found by accident and then afterwards asked if they were hiring...
