An introductory phone call, Online Assesment and Technical Phone Interview. The first two were good. The interviewer in the third was drowsy and kept on asking the same question again and again about my algorithm. I explained as many times as possible but he said he doesn't get it. At some points, I couldn't hear him. So I politely told him that but he never asked me if I can hear. He just continued with his scripted dialogues. Wasn't asked any behavioral questions or the complexities of my solutions at all.

It started with an OA, and then after a few weeks, I got invited to four rounds of interviews: technical and behavioral at 3 of the 4, and behavioral only at one.
