Last rounds - especially the case study - were weak and not really aligned with the actual business (focused on personal users, while the company serves business customers only). The interviewer in the case round did not seem to listen carefully and repeatedly asked the same questions after I had already answered them, and was quite confrontational. After completing a multi hour case study and three interviews, I received only a no-response generic rejection email with zero specific feedback. It's a poor hiring approach.
After reading negative company reviews, I feel lucky not to get through the next stage.
