I was contacted by phone by the HR department, who scheduled a phone interview. This interview was with two team leads and discussed what the department did, and asked questions about my experience and background. After this interview, I was contacted the next day by HR to set up an in person interview with a panel of team leaders. This interview was similar to the first, and then followed by an aptitude test.

very technical interview. Expect a lot of questions about coding, hierarchy, documentation etc. The hiring manager was not that technical but didn't want to disclose that. I found most of the other folks i interviewed with were competent in their roles.
