Did not pass the interview. The questions were pretty tough, with multiple steps and were very challenging. I should have studied LeetCode more and done harder/medium LeetCode problems involving algorithms, and also become more familiar with systems

The OA round is long and tedious. The coding questions were not very difficult, but the games that need to be played afterwards are kind of unclear on what they are assessing. I want to make sure that you are human.

I applied online. One coderpad, one phone screen, and then onsite. Onsite was 3 rounds. They took a long time after the HackerRank to get back, but after that, the process was quick.
