Online coding round followed by onsite hackathon in Hyderabad. Problem was pretty dumb like saving data in database and fetching from database. Mentors were assigned to respective teams. I designed front end and some backend part but mentor had no knowledge of both. So even I explained how I did it using framework he was not able to get anything. Some of the guys were already aware of problem statement. So no point of attending DBS. Company has no talent. You won't learn anything from these kind of mentors who are not able to understand simple code.
