My interview process consisted of six stages:

Initial Coding Interview – Solved 2 loop-focused algorithm problems.

Second & Third Coding Interviews – Two rounds, each with 2 algorithmic problems.

Behavioral Interview – Discussed past experiences, teamwork, and problem-solving approach.

System Design Interview – Designed a scalable architecture for a given scenario.

Follow-Up System Design Session – Dug deeper into trade-offs and data modeling from the previous design.

After designing the system using Kafka, Flink, and ClickHouse, the interviewer asked how I would solve the problem without using any of those technologies, building everything from scratch.

He gave me a generic queue and a generic database.
