One interview. Meet with HR, supervisor, then manager. HR is behavioral, very easy. Supervisor talks about what you would be doing, asks about your resume. Manager is more in depth about technical skills, asks same questions about resume.

I submitted my resume through a recruiter and they asked me to come in and interview 3 weeks later. Obviously they weren't in any hurry to fill this position. My interview was at 4pm and like any good candidate I got there about 15 minutes early but it took 10 minutes to park and walk to the building so I signed in at security at 3:55. I sat around until 4:20 before the HR person came to get me. When she showed up she didn't even offer an apology for making me wait so long. This made for a bad first impression. The HR person asked me one very basic question about my resume, went over the company benefits and had me fill out a background check form. She then left me sitting in a tiny room with no windows for about 15 minutes before she came back to get me. We then walked several blocks to another building where I met with the hiring manger. The manager was really nice and asked basic questions about my resume and talked about the department and the position. Then I met with another manager in a related department. He asked a few behavioral type questions and personality questions.
