Online coding test -> 2-4 technical rounds (DSA, system design) -> hiring manager + fit
The actual PhonePe interview loop
High-bar fintech loop known for hard DSA rounds and a machine-coding/LLD round, followed by HLD for seniors and a rigorous hiring-manager round; interviews lean on real payments-scale problems since PhonePe processes a dominant share of India's UPI volume.
1. Coding Screen
~45 min · MediumOne or two DSA problems at solid medium difficulty solved with complete working code.
arrays · hashmaps · binary search · strings
2. DSA Round
~60 min · HardHard algorithmic problems on graphs, DP, or heaps where the interviewer pushes to the optimal solution and clean implementation.
dynamic programming · graphs · heaps · segment trees
3. Machine Coding / LLD Round
~60 min · HardBuild a working module such as a wallet ledger, rate limiter, or splitwise clone with clean class design and concurrency awareness.
object-oriented design · concurrency · idempotency · design patterns
4. System Design (HLD) Round
~60 min · HardDesign a payments-scale system such as UPI transaction processing, reconciliation, or notification fan-out with correctness guarantees under partial failure.
distributed transactions · exactly-once semantics · sharding · Aerospike/KV modeling · failure recovery
5. Hiring Manager Round
~50 min · MediumDeep dive into systems you owned, production incidents, and trade-off decisions, testing ownership and engineering judgment.
project deep dive · incident stories · ownership · trade-off reasoning
6. HR Round
~30 min · EasyCompensation structure including ESOPs, level, and joining logistics.

- →How would you handle a wallet ledger with atomic debit-credit and reversal handling?
- →How would you handle fraud and risk scoring for QR merchant payments in real time?
- →How would you handle scaling transaction status checks when a partner bank degrades during peak hour?
- →How would you handle designing the merchant soundbox notification pipeline for payment confirmations?
