Sawtooth Software interview questions

I really enjoyed the process I went through. The first interview was a 30-45 minute behavioral interview, and the second interview was a 5 hour series of technical interviews and other things. It started with me teaching something (anything) to all of the development team for 15 minutes (I taught them how to make duck noises - they did awesome), then I went into a series of interviews about frontend design, test driven development, backend design, connecting to APIs and general OAuth knowledge, and many other subjects. I got interviewed by at least 12 different people (in pairs of two). I think they did this to let me meet most of the development team, so it was technical and behavioral at the same time to see if I would fit in. They took me out to lunch as well and let me play ping pong with someone. It was a really enjoyable process actually!

Just a quick half-hour with the Product Manager and a couple of team members. For the most part, they just asked about points on my resume and my background. They were very friendly. My only real complaint is that I felt the interview went well, but I didn't get an offer and it seems they have no interest in wasting 5 minutes to tell me how I could improve for future interviews.
