The first round questions were exactly the ones mentioned here. Had a great experience.If you follow the questions here you'll make it to round 3. Make sure you prepare well esp when it comes to trees, how its works and stuff like that and basic OOPS concepts (super essential) and language in my case it was Java. Didn't do well in the next round, rejected.But a great experience overall.

First round was an HR interview with a basic coding problem Second round was technical, with a slightly more difficult problem. The third round was technical, with a harder problem. I found the process a little disorganized; I had to write code in a Google Doc, only one interviewer interacted with me in the final interview. The final technical interview didn't seem like a great interview question to me.
