The interview process took 20 days.It was a pooled drive where top brass from each college were called for the process.Some thing like 25+ colleges were attending on the same day. The first round was Apti/C/Data structures.The next two were tech interview.It took some 25 days to get the final result.

Data structure and graph related questions were asked with some behavioural rounds. I would say it is Difficult on the 3rd round of the interview where they focus on leetcode problems.
