Airwallex Interview Questions & Answers

Q: Given a set of contradictory conditions, implement the logic to process a batch of user refunds.

A: Since the rules conflict, first clarify which condition wins, then encode the rules as an explicit precedence table so every refund resolves to one deterministic outcome. Process the batch idempotently so a retry never double-refunds.

Answer by AI
  • Ask the interviewer to rank the conflicting rules; a payments system needs one deterministic priority order.
  • Model each refund as a state machine and make the operation idempotent with a unique refund key so retries are safe.
  • Validate inputs, handle each record's failure independently, and log every rejected refund with the rule that blocked it.

Q: Design a high-availability transaction service that guarantees data consistency.

A: Use a replicated, partitioned datastore with quorum writes for strong consistency, and make transactions idempotent so retries after failover don't corrupt balances. Prefer an append-only double-entry ledger over mutable balances.

Answer by AI
  • Choose strong consistency for money movement: quorum writes or a consensus layer like Raft, not eventual consistency.
  • Model funds as an immutable double-entry ledger so every debit has a matching credit and balances stay derivable.
  • Plan for failover with idempotency keys, retries, and reconciliation jobs that catch any drift.

Q: How would you design the backend for a global treasury payment network to minimize latency?

A: Place regional processing close to users and settlement rails, route each payment to the nearest healthy region, and keep the hot path asynchronous so slow downstream banks don't block the response. Cache FX rates and account metadata near the edge.

Answer by AI
  • Deploy multi-region with geo-routing so a payment is handled near the sender and its local settlement rail.
  • Split the fast acknowledgement path from slow bank settlement using queues and async processing.
  • Cache reference data like FX rates and limits, and track p99 latency per region, not just averages.

Q: Walk me through how you would troubleshoot and resolve a sudden latency spike in a microservices-based payment gateway.

A: Read dashboards and traces first to find which service or dependency regressed, correlate the spike with recent deploys, traffic, or a slow database, then mitigate fast with a rollback, scaling, or load shedding before doing root-cause analysis.

Answer by AI
  • Start from metrics and distributed traces to localize the slow hop instead of guessing.
  • Correlate the spike with deploys, traffic surges, database locks, or a degraded downstream dependency.
  • Mitigate first (roll back, scale, add timeouts and circuit breakers), then run a blameless root-cause review.
