1. OA: 2 hours with 15 questions, quite hard, involved operating system, algorithm, and basic data structure 2. Technical interview: 45minutes to 1 hour with 1 leetcode medium question. Not that hard data structure and algorithm. The interview experience is totally up to the interviewer. Mine was so fun(with simple BFS) but my friend's is a bit harsh with heap. 3. Final round (9 am to 3 pm). Quite intensive. They asked you to write some small assignment questions. During the system design, they gave you quite interesting questions (not the typical type) and they wanted to know how much knowledge you know overall. Technical round is to review the code you just wrote, and asked many questions to test your overall ability which was quite overwhelming to me,

The process is 2 rounds of OA, then a 30 minute technical phone interview about resume, Python trivia, and little bit of behavioral questions, then a 15-minute behavioral interview, then the final round.
