Your question is Capacity Planning for Growth. Take a moment with it on the right.
Talk me through your thinking if you like. When you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes).
How would you perform capacity planning for a rapidly growing product?
Explain how you would forecast pipeline demand, identify bottlenecks, size ingestion and processing infrastructure, and plan storage and compute capacity. Cover batch and streaming workloads, peak traffic, growth uncertainty, cost controls, reliability targets, observability, scaling triggers, backfills, and disaster recovery. Include the measurements, assumptions, dashboards, and rollout process you would use to validate the plan in production.
