Was contacted by recruiter from staffing company, who met with me first and then scheduled the interviews promptly. Sat for interview first with my future direct supervisor, and then with another manager who would work closely with my future team (both back-to-back on same day). Interviews followed the STAR format and were very behavior-based. Spent more time on behavioral questions than on my actual resume/previous skills, although both interviewers were clearly familiar with my resume. Learned later that personality and perceived 'fit' with my future team were very important to the interviewers. Later, when I was moved from contractor to regular employee, I was interviewed again by the HR manager and the head of my department, although these interviews seemed more informal.
