Interview difficulty was medim has 3 rounds first was hld and tech discussion, second was manager discussion discussed about previous experiences and tech optimizations etc, Hr round was typical and had discussions regarding policies and salary.

6 Rounds in total Interviewer didn't know what role I was being hired for and Was the stack being used in the project or not all other rounds were just formality for him to reject you as they found a cheaper alternate. Not recommend just from the behavior of the interview
