System Design Mock Interview

Cleared DSA rounds before but stalled at system design? At Staff/Senior level, the bar isn't "can you draw boxes and arrows" — it's whether you can scope ambiguity, justify trade-offs under real pushback, and communicate like you'd actually own the system in production. That's what gets tested here.

Only for engineers preparing Staff/Senior-level system design rounds — this isn't an intro to system design fundamentals.

In this session:

1. A real HLD problem, worked live under interview conditions — scoping, capacity estimation, component design, trade-offs
2. Direct pushback on your choices, the way an actual Staff-level interviewer would probe them
3. Feedback on communication — how you structure the conversation, not just the diagram
4. A specific, prioritized list of gaps to close before your next real round

Why me: I led a 3-engineer team at Coinbase building a distributed, event-driven multi-agent platform (LangGraph, Kafka, Redis, Postgres) processing 10M+ events/day — decisions that cut LLM costs 70% (~$680K/year) and, combined with a separate infrastructure migration I led, saved roughly $1.2M/year. I'm IIT Indore CS, nationally ranked in ACM-ICPC, and went through my own dense stretch of Staff/Senior-level system design interviews in 2026 before choosing to rejoin Media.net as Tech Lead. This is what I was tested on weeks ago — not a rehash of a course.
