Public-pattern practice pack
Razorpay Backend Interview Practice
Practise backend questions around payment reliability, idempotency, ledgers, webhooks, security, and service observability.
Best for: Backend developers preparing for fintech-style engineering rounds
Example spoken questions
- 01Design a webhook consumer that remains correct across duplicates and out-of-order delivery.
- 02What invariants would you enforce in a double-entry ledger?
- 03How would you investigate a mismatch between payment status and merchant settlement?
What to practise
Focus areas for this track. Practise explaining each one out loud, not just recognising it.
- Idempotent APIs, retries, and duplicate-event handling
- Ledger invariants, reconciliation, and auditability
- Webhook security, queues, and eventual consistency
- Operational metrics, incident response, and safe rollouts
How to answer more clearly
Lead with financial invariants and failure handling; optimise throughput only after correctness is clear.
Mockery makes you answer aloud, then evaluates the transcript for technical coverage and missing concepts. It does not claim to predict a hiring decision.
