## Overview & Hiring Pattern
Razorpay is India's leading payment gateway and neo-banking infrastructure provider, powering payments for millions of businesses.

Engineering rounds at Razorpay probe deep financial safety and distributed systems:
1. Data Structures & Algorithms: Algorithmic problem solving focusing on arrays, strings, trees, and graphs.
2. Low-Level Design: Designing object-oriented ledger systems, rate limiters, and payment routing engines.
3. System Design & Distributed Systems: Building fault-tolerant webhook delivery engines, payment reconciliation systems, and high-availability banking gateways.

## What Sophia AI Evaluates in This Track
- 💳 Payment Idempotency & Webhook Engines — Exponential backoff retry policies, exactly-once webhook deliveries, and deduplication keys.
- 🔐 ACID & Transaction Isolation — Preventing race conditions in wallet debits, two-phase commit (2PC) vs Saga pattern in microservices.
- ⚡ High Availability Payment Gateways — Active-Active multi-region deployments, circuit breakers, and fallback payment routes.
- 📐 FinTech System Design — Design a Wallet Ledger system with double-entry bookkeeping and auditability.
- 🗄️ Relational Integrity & Deadlocks — Row-level locking (SELECT ... FOR UPDATE), isolation levels (Repeatable Read, Serializable).

## Frequently Asked Questions
### Q: What makes Razorpay interviews unique?
**A:** Razorpay focuses heavily on rock-solid financial consistency, idempotency, distributed transactions, database isolation levels, and zero-downtime microservices resilience.

### Q: What is Idempotency in payment systems?
**A:** Idempotency ensures that performing an API request multiple times (e.g. Due to network retries or timeouts) produces the exact same result as a single request, preventing duplicate debits.

### Q: What are the typical interview rounds at Razorpay?
**A:** The rounds include: (1) Coding & DSA Round, (2) Low-Level Design / Machine Coding, (3) High-Level System Design (FinTech architectures), and (4) Culture & Engineering Manager round.

### Q: What is Double-Entry Bookkeeping in system design?
**A:** Double-entry bookkeeping mandates that every financial transaction must have equal and opposite debit and credit entries, ensuring that total debits always equal total credits across accounts for complete auditability.

### Q: What compensation does Razorpay offer for SDE-1 and SDE-2 roles?
**A:** Razorpay offers ₹20–30 LPA for SDE-1 and ₹35–52+ LPA for SDE-2 with substantial ESOP components.
