Recruiter screen then there was a hiring manager round which felt more like a mix of product sense + execution - mostly a mix of OOP algorithms in Python or Java and some high-level system design. The onsite was 5 back to back rounds covering data structures, database management (heavy on SQL and data lifecycles), deep sys design, and behavioral. The sys design round was the real test where I had to walk through building a scalable real-time gaming leaderboard, discussing tradeoffs ofcourse in architecture, APIs, and data flow. The coding rounds was around things like linked lists and tree traversals, while the behavioral part focused heavily on ownership of my code and handling feedback. When you prep, make sure you can go a level deeper on database management and object oriented patterns instead of just grinding LC I’d say. I did grind LC though but ensure you understand the depth behind everything you solve. I also did a few mocks with uber swe on prepfully specifically for the sys design and database rounds and that honestly helped me catch some blind spots in my architecture knowledge and practice explaining my tradeoffs clearly. I’d say get a mock or two from anywhere if you can - helped me a lot!
