Three interviewers. First was an HR representative who went over benefits, then the general engineering manager who asked more general and focused on my background. HR was supposed to to the third, but was unavailable, so a team lead conducted the interview. She asked more technical and situational questions

Interviewed with three people: a person from HR, a Project Manager, and a higher level Systems Engineer. The interview was an hour and a half long, and I was asked various technical, behavioral and situational questions.
