The initial pre-screen interview was over the phone. It was with a company recruiter, and it was mostly about the company, it's growth, and it's culture. Some odd jokes were made, mostly to gauge my personality.
The second interview was a face to face with some development team members. They seemed slightly disinterested, and did not smile much. A nerf-gun was also on-hand by one of the team members. Their questions were made to gauge my understanding of C#. They weren't overly technical, but some were about obscure areas of code, which are not often, or rarely used.
