You will first have a phone interview with HR and the hiring manager. If it goes well, they will set up a site visit where you will interview for about 3 hours and take a quick tour of the site. The interview is split up into two sessions. Both sessions include you and two managers. In each session, the managers have a list of generic questions (about 10-20) that ask about how you have handled a bad situation in the past, how you deal with coworker conflict, how you have solved a problem in a previous job, etc. In the second interview session, the two new managers ask essentially the same questions, and your job is answer without duplicating your answers in the previous session. They will ask you a little about your experience, work history, why you want the position, etc. It isn't difficult, just long.

The interview was conducted with two pairs of supervisors who asked the same set of questions that lasted about 30 minutes each. They then reviewed the responses to which they applied a score and used that score to decide which applicants to select.
