Full-Stack Developer Interview Questions and Answers

A broad interview preparation book for full-stack developers. It covers frontend and backend integration, APIs, databases, authentication, security, caching, system design, debugging, testing, and behavioral answers. Read one chapter at a time, answer the questions out loud, then write a short version of each answer. The goal is not to memorize scripts. The goal is to build clear, practical answers that show judgment, implementation skill, and professional communication.
