Problem

Design rate limiting (discussed in the context of the candidate's current projects). Asked in the Design round stage. The discussion may also cover Airflow orchestration system design, Docker, PostgreSQL, Elasticsearch, and Django fundamentals.

Address the following:

Clarify rate-limit dimensions, policies, and client behavior.
Design the request path, limiter state, and distributed coordination.
Compare token bucket, leaky bucket, fixed window, and sliding window approaches.

Discuss testing, capacity planning, and safe rollout.

Do not assume product-specific traffic, infrastructure, or business requirements unless you explicitly state the assumption.
