Real-life Scenario-based Interview Questions
Scenario-based Q&A for SDE-2 and Senior loops — payments, concurrency, Kafka, caching, multi-region partitions, sagas, and ops failure modes. Each answer is written the way a strong candidate talks in a 45–60 minute interview: framing, core design, walkthroughs, weak answers, and follow-ups where they add depth.

How to use this section
- Interview bar: Read the question, pause, answer out loud — then compare with the write-up. Focus on framing and trade-offs, not memorizing prose.
- Importance: Start with Must Know, then Important, then Advanced. Optional is extra depth after the core set.
- Search: Filter by keyword in the title or tags (e.g.
Kafka,idempotency,refund). - Access: When the Interview Questions flag is free for everyone, all answers are open. Otherwise new users get a 30-day free trial with full access; after that (or for older accounts), the first 5 questions stay free — unlock the rest with a subscription.
