Initial interview with founder to get a general understanding of the role, my own experience, as well as ask any questions. Casual and fairly free flowing conversation with good opportunity to get a better understanding of what they were looking for.
Second interview with Tech Lead, which again was a friendly and personable chat. Questions were more of what you would expect in the 2nd stage of the process in that they were based around previous experience and providing examples.
While I didn't get an offer it was a generally positive experience and I was kept informed throughout.
