I applied through a recruiter. It was much easier than I expected. It started off with a technical HackerRank screening of two medium and one hard LeetCode problems. - 1st Round: System Design and LLD of something like a sports scoreboard (30 mins)

Questions on graphs and other topics were covered over four rounds. It was not that hard, but DSA practice is needed to clear it. The design round was mostly based on my experience, so if you have done design work, you can do it easily.

I applied through a staffing agency. There were two interviews. - The first one was focused on system design. - The second one was a review of my entire career, with a discussion of the biggest challenges and a lot of technical details.
