API Testing and Realtime Interview question

API Testing Interview Questions — The Complete Prep Guide

Stop guessing what they'll ask. Walk in already knowing.

Most candidates freeze up the moment an interviewer says "walk me through how you'd test this." This guide fixes that — with real questions, real answers, and real scenarios, not textbook theory.

📦 What's Inside

• 70+ interview questions — Beginner → Intermediate → Advanced → Architect level
• 15 real scenario questions — the exact situations interviewers actually describe
• 50-question mock interview — 5 timed rounds, answer before you peek at the model answer
• 26-term glossary — every acronym explained in plain English
• 10 comparison tables — the tricky pairs (PUT vs PATCH, Mock vs Stub) made obvious
• 8 custom diagrams — visuals for the concepts that never stick from text alone
• 6 REST Assured code questions — for when the interview goes hands-on
• 3 real-world project walkthroughs — banking, third-party integrations, rate limiting

🎯 Every Question Comes With

• A short answer you can actually say out loud
