#System Design

How do you maintain database consistency, prevent double booking of seats, and manage seat inventory during high-concurrency booking scenarios?

How would you utilize Redis caching, distributed counters, and cache expiration / TTL to handle high-frequency search traffic and demand detection?

Design a Flight Booking System. Specifically focus on how you would dynamically change flight prices when a surge of users are searching for the same flight, factoring in dynamic pricing, demand signals, and concurrent flight searches.

Have you worked on High-Level Design (HLD) and Low-Level Design (LLD)?

Why did you choose a microservices architecture instead of a monolithic architecture?
