What are the most important things to learn for a QA tester job with no experience?

H2K Infosys highlights that starting a QA tester career with no experience requires focusing on core fundamentals. Learn software testing basics such as SDLC and STLC, types of testing (manual and automation), and defect life cycle. Gain hands-on practice with tools like Selenium, Jira, and TestRail. Understanding basic programming (Java or Python) and SQL for database validation is highly valuable. Develop strong analytical thinking, attention to detail, and communication skills. Familiarity with Agile methodologies and version control systems like Git also helps. Building small projects and real-time practice scenarios will significantly boost confidence and job readiness in QA testing.
