I gave them my resume at their booth at a career fair. I received an email a week later from HR asking to set up 3 phone interviews within the next few days. The questions were primarily behavioral and less on the technology side. I think they were just trying to gauge how you would fit on the team on a personal level, such as whether or not you'd be fun or easy to work with and if you would generate any problems with the team and if you were a team player. HR was quick to respond to emails and the interviewers were calm and nice. I'd say it was a pleasant experience for me.
