Model answer
Try answering aloud first
Cover trade-offs, structure, and a concrete example before revealing the baseline response.
How to frame this at Flipkart: Connect your answer to measurable impact, clarity of thought, and trade-offs the team cares about. Below is a strong baseline response you can adapt with your own project examples.
Laravel queues run jobs asynchronously via drivers like Redis, SQS, or database. Configure retry attempts and backoff so transient errors are retried without immediately failing user workflows.
Use job-level tries and backoff controls, and route exhausted failures to failed jobs storage for inspection and replay. Idempotent job handlers are important because retries can execute the same logic more than once.
Mention operational hygiene: monitor queue lag, separate critical queues, and tune worker concurrency by workload type.
