Mock Interview — System Design (HLD/LLD)

A realistic 60-min system design mock targeted at senior SDE / Backend roles.

Format:

• 40 min: live design problem (you whiteboard, I probe like an interviewer)

• 20 min: detailed feedback — what worked, gaps, follow-up reading

Problems I draw from (pick or surprise):

• Design a URL shortener / rate limiter / chat service

• Design a payment system (real Snapdeal-style flows)

• Design a microservice for cart, checkout, or inventory at e-commerce scale

• Design a voice agent platform with real-time conversational AI

• Design an LLM-powered analytics pipeline

You'll get the real-world version of the design — not just textbook patterns. I'll share trade-offs I actually made shipping for 50M+ orders/year at Snapdeal and voice agents in production at FabHotels.

Best for: 2-6 year SDEs preparing for senior backend interviews.
