A friend referred me, and then a recruiter reached out. I quickly scheduled the first round with the hiring manager. After passing it, three final rounds were scheduled.
The first round was with the hiring manager. They presented a coding problem, a variation of the "word ladder" graph problem, and asked for improvements, specifically regarding multi-threading. Running and testing the code was not required.
The second round involved two engineers and was a problem-solving session. We were given a piece of code and asked how to improve it, again focusing on multi-threading. Only pseudocode was needed.
The third round also involved two engineers and was a system design round. It was not a typical system design problem but rather a real-world work-related issue.
