Round 1 was a phone interview with the hiring manager. That was the pretty standard easy interview that gets your foot in the door at any company. Nothing too difficult was asked, it's mostly about gauging your interest and hearing about the job. Round 2 is the tricky bit. It's a HR interview that tries to figure out if you're the physical incarnation of their fabled company values. If I were you, I'd have a story ready for each one of them because the interviewer expects you to ramble on and hang yourself if you don't have good answers. I've never talked to a shrink but I got a feeling it is very similar. They ask a lot of deceptively simple questions whose answers probably don't really matter on the surface. I think round 3 is a technical phone screen; round 4 is a in person interview, and round 5 is a flight to the mothership.
