Reached out to me in email. Overall very friendly, the interview for the position I was going for covered concurrency and multithreading in Java, which I thought was not too bad. Overall my downfall was my own lack of knowledge of the technologies being used.

The interview was pretty long - got in around 10am and stayed until 5pm, it included a programming test in Java with concurrency questions, a system design test, then a few behavioral/personality interviews with first peers, hiring manager, and finally the CEO.
