It was about a position inside a team. The first interview was with one of the team members and took approximately half an hour. After a few days I was informed that I passed in the second phase and a day of several different interviews followed along with a presentation from me to them.

I applied with a referral from the company. First phone interview with the hiring manager and recruiter. After the phone interview, they arranged behavioral interviews with everyone on the team, including engineers and managers, questions asked including team work, projects.
