I first interviewed by HR of the company , she was very helpful and positive , she asked general questions about me . After first interview she set another interview with the technical team . Technical interview was quite long (almost 2.30 hours). They asked me some algorithm questions and general questions about computer science . After the questions they challenged me with a live coding test . They watched my live while i was writing code in a real time collabrative text editor . Interviewer was competent in javascript and he was very helpful .
