Preparing for a FAANG or top-tech system design interview? I run realistic system design mock interviews — High-Level Design (HLD), Low-Level Design (LLD), and scalable distributed systems — under true interview conditions.

I've interviewed with and worked alongside engineers from Amazon, Meta, Apple, Uber, and Atlassian, and I've conducted 1000+ interviews across FAANG and high-growth startups. I know what the bar actually looks like at each level.

WHAT YOU GET • A realistic 45-minute system design question (HLD and/or LLD) • A true interviewer-candidate simulation — including follow-ups and pushback • 15 minutes of structured feedback: strengths, gaps, and trade-offs you missed • Deep dives on scalability, consistency, availability, latency, and cost • Coaching on how to structure and communicate your design under time pressure • A written summary with a concrete study plan for your weak areas

TOPICS COVERED Load balancing, caching, sharding and partitioning, replication, CAP trade-offs, SQL vs NoSQL, message queues and Kafka, rate limiting, CDNs, consistent hashing, idempotency, observability, capacity estimation, API and schema design, and classic LLD problems (parking lot, rate limiter, notification service, and more).

WHO THIS IS FOR Junior, Senior, Staff, and Principal engineers who can build systems but freeze when asked to design one on a whiteboard in 45 minutes.

BEFORE YOU ORDER Message me with your target company, target level, and interview date. I'll pick a question that matches the real loop for that role instead of a generic one.
