Applied online. Received a call within two days from friendly HR lady to set up on-site interview. Had a choice of times & days. Directions to company were clear, and she wished me a good interview - I liked that. Interview for my position spanned about 1 hour 15 minutes. Met with three people (20-30 mins each), one was CIO. He was disarmingly friendly and we talked mostly about culture. Other two were ScrumMasters (peers) who grilled me with scenario-based questions and others from industry readings and CSM coursework. They also expressed desire to have me join the team. Looking back, they didn't sugar-coat the challenges, but they kept their promise of helping me transition and work as a team. Good guys who care about their teams and promote sustainable pace. (and they host an Agile meetup after work on site.)

I talked with 3 people about the job. They asked straight-forward questions about how scrum works, which I didn't have to strain to answer because I've been living it for years, and its not a very complicated topic in the first place. Posers would get blown out pretty quickly, though. So, it makes no sense trying to cram for an interview.
