It was tough. I was asked data structure and algorithms questions about trees. There were a total of two rounds. The question was from LeetCode. I was not selected, even after my interview went well.

I applied online. The process took 4 weeks. First, they discuss yourself and some questions from your resume, then they move to mid to hard DSA questions, which include dynamic programming, matrix, and graphs, and they also want to hear the approach

It was a 2-3 round process, depending on how your interview went, with increasingly hard DSA questions followed by some HR and behavioral questions. First round was mostly easy and medium LeetCode, followed by medium and hard questions in the second
