Was already a contractor, so had a relatively easy interview. Just asked the usual quesitons
The interview actually consisted of him explaining the company to me more so. I got the sense that I already had a good chance of getting the job.
I was in a room with the guy who turned out to become the Head Manager of the department. He was quite nice and casual. The interview took place in the same office as the job, it was not overly long, probably took 30-40 minutes.
