Once my Mgr needed to reject a dev who had said something that did not vibe well with another manager, engaged the candidate in another round of tech interview with a L1 candidate who was working as a dev in the same team. (L1 is supposed to be a Mgr but worked as dev to sideline the immigration process). The candidate was asked offbeat Mockito unit test questions with the intention of rejecting. Speak of Hazing, some interviews are setup to reject candidates for the sake of rejecting.
