Pergunta de entrevista da empresa Cohesity

DSA question was very basic. HLD round was good. They gave a problem statement from their current work and asked how would I approach the problem. This round went good. LLD round: Interviewer was quite unprofessional. Unnecessary requirements in the problem statement which is not even a genuine use case in the industry. I couldn't solve the question here. HM round: Felt like he already made his mind from Round 3 feedback and this round was just a formality. Because of the unprofessional behaviour during Round 3, I am rating this as negative experience.
