In simple word, it's pathetic. The CTO was screening me through telephonic interview in a rude manner, It was kind of investigation rather than assessing a candidate. The interview questions were pretty simple which includes distributed system, database internals, etc.
I was contacted by the recruiter and had in-office interview. They gave assignments to work on and then there was an interview with the panel which lasted for about 1 hour. The interview panel was very rude, incompetent and did not know answers to the questions they were asking. Questions were pretty much out of the book theoretical questions. This process took almost 5-6 hours and still they were not able to decide whether to hire or not. Only go if you want to waste your time.
I applied online. I interviewed at CallHub (Bengaluru) in Apr 2017
