First online test: * Aptitude * DSA * Language-based questions (PHP, C++, Java) Second technical interview: * LeetCode medium to hard level questions. Topics included strings and dynamic programming. Third round (HR): * Basic behavioral question

Asked Leetcode Medium to Hard level question, and the interviewer was very interactive and very, very active throughout the process. I feel a person who is strong at the DSA can qualify this round.

I gave an interview 2 years back. It was a medium to easy process. They mainly focused on DSA. "Tell me about a time you faced a difficult challenge," or "Describe a situation where you worked in a team to solve a problem."
