H2K Infosys recommends building a strong foundation in both technical and analytical skills to become a successful QA engineer. Start by learning software testing fundamentals, including manual testing, test case design, defect tracking, and test execution. Gain knowledge of SDLC and STLC processes, Agile methodologies, and testing tools such as Jira. Learning automation testing with Selenium, Cypress, or Playwright can significantly improve career opportunities. Basic programming skills in Java, Python, or JavaScript are also valuable. Additionally, understanding databases, API testing, and performance testing helps QA professionals handle complex applications. Strong communication, problem-solving, and attention-to-detail skills are equally important for long-term success in quality assurance.
