It was a really fun interview process! I got four interviews, and there was a final round after that. The problems asked were interesting and challenging and I had a great time. I'm excited to apply again soon!

1. Coding & Algorithms Expect standard algorithm and data structure problems (like from LeetCode). Emphasis on clean code, optimal solutions, and reasoning. Examples: Implement a cache with O(1) access. Design a rate limiter. Solve graph traversal or dynamic programming problems. 2. Systems Design / ML Systems Design robust, scalable systems—often in AI/ML contexts. Examples: How would you design a distributed training system? How do you deploy and monitor a large language model in production? 3. Machine Learning & Deep Learning (for relevant roles) Deep understanding of models (transformers, diffusion models, etc.) Expect questions about training dynamics, loss functions, and optimization. Examples: Why does layer normalization work better than batch norm in transformers? How would you debug a model that's overfitting?
