Four steps:
A phone interview with the hiring manager
An interview with the team I’d be working with
Written skills test
An interview with the boss of my boss
Everyone was friendly. The phone interview was easiest, just asking about me and telling me about the position. The second was a couple hours long and involved about seven people! Everyone was really nice, though. By the third, the executive admitted he was just about convincing me to take the job. I enjoyed it overall.
