// Interview Prep/Coding for QA
💻 Coding for QA interviews.
The coding fundamentals QA interviewers actually test. You don't need to grind LeetCode — but you do need fluent JavaScript/TypeScript, confident SQL, solid Git, and (for some shops) Java. These banks cover what comes up in real QA interviews.
// 5 BANKS
JavaScript
The automation stack — async/await, closures, Promises, and the event loop. You write Cypress, Playwright, and Node test code in this language every day.
TypeScript
Typed test automation — interfaces, generics, utility types, and narrowing. Most modern automation projects use TypeScript; interviewers test whether you can use it deliberately.
SQL
Data validation and back-end checks — joins, aggregates, finding duplicates, and verifying migrations. Essential for any QA role that touches back-end or data pipelines.
Git
Everyday engineering workflow — branching, rebase vs merge, conflict resolution, bisect, and stash. Interviewers treat fluent Git as a baseline professional skill.
Core Java
The Selenium, REST Assured, and Karate stack — OOP, collections, streams, exceptions, and concurrency. Required for any Java-based automation shop.
