I applied online. The process took 2 weeks. I interviewed at Skillz (San Francisco, CA) in Sept 2016
Interview
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.
I applied through other source. The process took 1 week. I interviewed at Skillz (San Francisco, CA) in Mar 2017
Interview
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.
