May be the worst interview experience ever. I was reached out by the HR who's friendly and energetic, but the case interview is completely different vibe. The interviewer was late for 2min, without any self-intro, closed his camera for entire process, and seemed not interested in who am I at all. I've been told to do the case as a management consulting one, but got a hard cut-off when walking through the calculation saying "JUST GIVE ME THE ANSWER".
