Candidates search for top 100 manual testing interview questions because they want:

  • One complete place to revise everything
  • Confidence before interviews
  • Coverage of interview questions for QA, not just theory
  • Exposure to real-time manual testing questions

Whether you are a fresher, junior tester, or experienced QA, this guide helps you revise:

  • Fundamentals

  • Real company interview round questions
  • Best answers to manual testing interview questions

What is Manual Testing? (Simple Definition with Example)

Manual Testing is the process of testing software manually without using automation tools to identify defects and ensure the application works as expected.

Simple Example

Testing a login page:

  • Valid credentials → Login success
  • Invalid credentials → Error message
  • Empty fields → Validation message

You perform these actions manually and compare actual vs expected results. That’s manual testing.

Why Companies Ask Manual Testing Interview Questions

Companies ask manual testing interview questions because:

  • Manual testing is the foundation of QA
  • Automation depends on strong manual understanding
  • Humans catch usability and business logic issues

Real Workplace Angle

In real projects:

  • Requirements change
  • Deadlines are tight
  • Users behave unpredictably

Interviewers want QA engineers who:

  • Think logically
  • Handle real-time issues
  • Communicate clearly

That’s why scenario-based questions and real-time manual testing questions matter more than memorized definitions.
