이 직무의 면접 팁
- Give candidates a feature description and ask them to generate test cases on the spot. This reveals their testing instincts and edge case thinking.
- Include a practical automation exercise if the role involves test automation. Having someone write a simple automated test reveals more than discussing frameworks theoretically.
- Ask how they handle flaky tests. This is a universal challenge and their approach reveals testing maturity.
- Assess their relationship with developers. The best QA engineers are collaborative partners who improve quality across the team, not adversaries who just file bugs.
자주 묻는 질문
Should QA engineers write code?
For modern QA roles, yes. Test automation is now a core skill for most QA positions. Candidates should be comfortable writing automated tests, scripting test data generation and working with CI/CD pipelines. Manual-only testers are increasingly limited to specific niche roles.
How many QA engineers should a team have?
There is no universal ratio, but 1 QA engineer per 3 to 5 developers is common. More important than the ratio is the team's quality culture. In mature teams where developers write thorough unit tests, QA engineers can focus on integration, end-to-end and exploratory testing rather than finding basic bugs.
What is the difference between QA and testing?
Testing is the activity of finding bugs in software. Quality assurance is a broader discipline that encompasses test strategy, process improvement, risk assessment and quality advocacy across the entire development lifecycle. A QA engineer does much more than execute test cases. They help prevent bugs through better processes, reviews and standards.
