1. Overview: Why Software Testing Internships Matter
A software testing internship is often the first real step into the IT industry. Interviewers hiring interns don’t expect deep production experience—but they do expect strong fundamentals, curiosity, and a learning mindset.
When you prepare for software testing internship interview questions, interviewers mainly assess:
- Clarity of testing basics
- Ability to think logically
- Understanding of manual testing
- Awareness of automation, API, SQL
- Willingness to learn and ask questions
- Communication skills
This guide is written specifically for internship-level interviews, combining theory + practical thinking, using real industry language, not textbook definitions.

- Duplicate
- Deferred
- What is defect severity?
Severity defines the impact of a defect on the system. - What is defect priority?
Priority defines how urgently a defect should be fixed. - Difference between severity and priority?
| Severity | Priority |
| Technical impact | Business urgency |
| Set by tester | Set by lead/PO |
What is a blocker defect?
A defect that stops further testing.
