Pleasant. Did not ask any question regarding my current job/project. General discussion on past experience and approach to problems in my field of work.

initially contacted by colleague for lunch, followed by another lunch interview with his manager. Then was invited for an on site panel interview with a couple interviewers participating from the bridge. Went over my resume and was asked several follow up questions. A week later, had a phone interview with HR manager. Another week later, and I had an offer to consider.
