There were three DSA rounds, all covering different topics with follow-up questions. No need to go into advanced topics like tries; basic data structures are sufficient. The interviewer ensured you were comfortable throughout the process.

Very smooth process with medium to hard level questions for the OA and the interview. I applied as an intern and had 90 minutes to solve two questions: one easy and one hard.

A basic intro and drove into 2 leet code easy-medium level questions. * One was leetcode balloon and arrow question. * The other one is path sum in a tree. The interview was easy but I choked.
