The best interview process I had. The first contact was with Steve from their HR. Steve is a great guy who introduced me about the company and job. After that, they sent me task which I needed to do in a several hours (4-5h if I recall corectly) and then I had skype meeting with great guy Leandro. We talked about many topics regarding software development, coding, communication.... the final step was to come in Berlin (they cover all costs for me to come from Serbia and spend some time there), to meet the team, do some team excesize, talk with pms, cto and so on... Even I didn't started to work for them, it was one of my best interview experiencies. I met a lot of great and interesting people there and I think it would be great working with them.
