Backend + System Design Mock Interview with Apoorv Goyal

A realistic 60-minute backend interview, run the way product companies run it, followed by honest, specific feedback.

Pick your round when booking:

• System design (HLD): design a real system end to end, from requirements to scaling and failure handling

• Low-level design / machine coding: model a real problem in clean, extensible code

• Backend deep dive: APIs, databases (PostgreSQL, Redis), queues, caching and trade-offs

What you get:

• About 45 min of interview + 15 min of live debrief

• A written scorecard after the call: what went well, what would cost you the offer, and what to practise next

• Problems inspired by systems I've built in production: UPI payments at Juspay, notifications and reports at Oro, automations at Deel

Best for: engineers with 1-6 years of experience preparing for SDE-1 / SDE-2 / Senior backend roles at product companies and startups.

Before the call: share your resume, target company/role and the round you want, so I can tailor the problem.
