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.

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.
