Technical Interview Prep
Master key algorithms, custom hook patterns in React, and indexing in relational databases.
Q: What is the purpose of database indexing?
A: Indexes speed up data retrieval by creating lookup tables, avoiding full table scans. However they slow down write operations because indexes need updating too.
Q: How does Next.js App Router perform caching?
A: It uses four caches: Request Memoization, Data Cache, Full Route Cache, and Router Cache — each serving a different layer of the request lifecycle.
Q: Explain React state batching.
A: React groups multiple state updates into a single re-render. In React 18+, automatic batching covers setTimeout, promises, and native event handlers.
