OA + 2 Technical Rounds + Hiring Manager Call. OA consisted of 3 relatively difficult problems. Technical Rounds were easier, and pretty standard for what you can expect from big tech. Hiring manager round is mostly a culture fit check, depending on the HM.

It was a proctored technical interview, consisting of 3 problems increasing in difficulty. They were akin to easy to medium difficulty leet code problem difficulty. There was no person to person interaction. I had to record myself solve the problems.
