The first round was a behavioral interview, they're looking for people with a mix of CS and CE. Even though they allow CS majors to apply, if you don't know hardware stuff it's definitely a drawback. Interviewer was a bit weird, showed up 20 minutes late and talked for the majority of the interview about his own experience and the offers he got out of college.
