Software Engineer Interview Experience
Interview process
The process was technically rigorous and focused heavily on ML systems fundamentals rather than generic LeetCode-style interviewing. The conversations went deep into large-scale training, distributed systems, performance bottlenecks, and reasoning about how computation and communication interact across GPUs. I thought the strongest part of the process was that I could connect several questions back to practical GPU and systems work I had done before. The harder parts were questions that required quickly reasoning through unfamiliar distributed-training scenarios and communicating the tradeoffs clearly while working through them.

Interview tips
Be very comfortable with distributed training and understand DDP, FSDP, tensor parallelism, pipeline parallelism, and sequence parallelism beyond just their definitions. Know what is sharded versus replicated, what communication collectives each approach requires, and how compute, memory bandwidth, interconnect bandwidth, and synchronization can become bottlenecks. I would also review PyTorch fundamentals, transformer training, GPU profiling, mixed precision, and practice explaining performance problems quantitatively rather than only describing optimizations conceptually.
Company culture
The team came across as highly technical and interested in understanding how candidates reason rather than simply whether they knew a specific answer. The discussions felt collaborative and engineering-focused, with an emphasis on digging into performance problems from first principles. I also got the impression that the role sits close to both research and systems engineering, so there is a strong expectation that engineers can move between model-level reasoning and low-level performance work.
