Overview

For each question, first explain the approach in plain language, then write the solution, then discuss edge cases. In Playwright interviews, the strongest answers connect JavaScript/TypeScript knowledge to reliable automation design. A strong coding answer usually covers: input assumptions -> approach -> code -> edge cases -> complexity/reliability -> how the same

How to Use This Workbook

Do not memorize these programs line-by-line. For each question, first explain the approach in plain language, then write the solution, then discuss edge cases. In Playwright interviews, the strongest answers connect JavaScript/TypeScript knowledge to reliable automation design. A strong coding answer usually covers: input assumptions -> approach -> code -> edge cases -> complexity/reliability -> how the same idea appears in automation. • Attempt each problem before reading the solution. • Run the code in Node.js or your Playwright TypeScript project. • Rewrite solutions in your own style so you can explain them confidently. • For Playwright questions, prefer state-based synchronization and semantic locators over fixed

Interview Mindset for Playwright Coding

Playwright QA interviews rarely test algorithms in isolation. Interviewers often want to see whether you can transform data, model it with TypeScript, control asynchronous work, write stable locators, validate APIs, and build reusable utilities without hiding failures. Prefer clear code Readable automation is easier to maintain than clever one-liners. Use TypeScript intentionally Types should catch mistakes at compile time and communicate contracts. Understand async/await Missing await is a common source of unpredictable automation behavior. Use Playwright auto-waiting Wait for states and events instead of arbitrary sleep calls. Design for diagnostics Strong frameworks capture enough context to debug a CI
