I would say this was the most interesting set of interviews I had. They first phone screened me and asked me about my past projects and a few python questions which were relatively easy. Then they gave me a take home project which required me to design a game player. It was quite interesting because I got to test my algorithm on their web server. The project was very clearly written and tested my ability to come up with creative solutions. Then we had a skype meeting to discuss more about my projects and get to see them. The interviewers were very professional and nice. They encouraged me when I had a difficult time. Overall, it was one of the most fun and interesting interviews I had and I learned a lot about the company and the industry as well.
