FAQ
Does Stripe have a system design round?
Yes. In the Stripe loop this shows up as "API design": Design a clean, robust API; correctness and edge cases matter.
When do system design interviews start mattering?
Usually from mid-level (L4) and up, becoming dominant at senior and staff levels. For new grads it is often light or absent.
Do I need to know exact numbers?
Not exact, but you should be comfortable with back-of-envelope estimation (QPS, storage, bandwidth) to justify design choices. Order-of-magnitude is what matters.
