Applied on their website, contacted by a recruiter about 3 weeks later for an interview. Interviewed a few days after that. One interview with a tech lead, 85% discussing experience, 10% technical, 5% just for fun talk. Very relaxed and enjoyable. Received offer about 2 weeks later. I've only done commercial-sector work and, compared to it, there's a lot of paper work involved.

There was nothing difficult or unexpected at all.
