7 rounds of interview spanning over a month, each eliminating and at the end a nondescript rejection mail with no feedback whatsoever. Had to redo the machine coding round cause the api they came with was broken. So essentially 8 rounds and still not even the courtesy to explain the rejection. Apart from the last system design round which was at best average, I aced all the other round. 1 recruiter screening, 3 coding rounds, 1 machine coding, 1 system design, 1 hr manager round. Apparently they like to pretend they are Faang with none of the courtesy or professionalism.
