The first round was a coding test that asked about knapsack problems. The next round was an interview with the panel. They asked dp questions and trees questions. The questions were of medium level.

It was an on-site round. Mostly, they asked data structure and algorithms questions, and some behavioral questions. The questions were mostly medium to hard level. If you have practiced enough, you can crack it.

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.
