After OA, there are 3 rounds, all onsite. First round was LeetCode Hard. I came up with a brute-force solution quickly but took time to develop the optimal solution. The interviewer was very friendly and helpful. Second round involved two LeetCode

The quiz was automated, with no human interaction. There were a couple of questions, and it was timed.
