Mock Interview (System Design)

System design interviews can feel vague and intimidating, but they don’t have to. As an SDE III at Flipkart, I’ve designed and scaled systems that handle 80K+ concurrent users, 30K QPS, and cross–data center replication using technologies like Apache Pulsar, Redis, and Spark. In a mock system design session, you’ll get a realistic interview experience, clear feedback on trade-offs, scalability, and communication, and guidance to structure your answers like a top-performing candidate.
