First, I spoke to a recruiter. I was sent an online assessment, which I passed. Then, I did a virtual interview. I felt I did well in the interview, but I didn't pass. I believe I failed due to a cultural match issue rather than technical abilities.

One technical question was asked, followed by questions on how to make the algorithm efficient. Explain the approach and talk about your thinking process. Ask questions to get your doubts cleared.

It was tiresome, but they were very fast when getting back to you. They were very friendly and offered a relatively fair and standard interview across the board, despite the different skills on the resumes.
