Initial interview with hiring manager involved general questions about experience, a math question. Then a long test for 2 hours about a bunch of topis from OOPS, programming, general computer vision,math. Then they asked a presentation about work done so far. After passing all the rounds, and also discussing compensation they rejected citing a petty reason that they knew all along about my application. Absolutely no respect for candidates time.

In one week got interview call after applying. First round was with senior engineer. first round - technical, second round - take home assessment, 3rd round - technical, 4th round - presentation, 5th round-HR.
