One phone interview with HR, then after about 1 week, One phone interview with the hiring manager. Two weeks after the phone interview, there is the on-site interview. The process is efficient and happy.

There were 2 rounds of interviews. First was the initial / HR interview through phone call. Second was the technical interview with the sr. programming manager. It went more in depth through your experience and there were a few technical questions centered on the programming languages I knew (Java). I didn't prepare enough beforehand so I wasn't accepted sadly. But the interviewer was nice and chill about it.
