What does a QA engineer do?

They plan and run tests, report bugs clearly, automate repeated checks and help the whole team build quality into each release.

Do testers need to code?

You can start with manual testing, but most roles now expect some automation. Learning one language and one automation tool greatly widens your options.

Is a certification required?

No. Certifications such as ISTQB Foundation can help a CV, but employers value practical skill and a portfolio of test work more.
