There were series of interviews starting from the initial HR interview. In the technical interview, there were solution architects from different departments and everyone asked their own set of technical questions.

I recieved a phone call by one of the two people that would later interview me. She asked me 15ish technical questions and skipped a bunch of the others. The very next day they wanted an in person interview. I met my contact and she took me in a room and threw some light questions at me and then a man "burst" through the door and immediately started asking more technical questions and really drilling in. It seemed like a good cop bad cop kinda ploy and very unproffessional. It was almost like they were bored with interviewing and wanted to mix it up. The only reason I put the interview was difficult is I wanted to tell them how stupid they were being but had to hold my tongue.
