The SDET junior-level interview process combines technical coding assessments, framework design discussions, QA process evaluation, and behavioral interviews. For a junior SDET, expect 5-6 rounds over 3-5 weeks emphasizing practical automation skills, basic system design of testing infrastructure, understanding of testing fundamentals, and collaboration with QA and development teams. Interviewers assess your ability to write clean automation code, design scalable test frameworks, understand CI/CD integration, and grow into a hybrid engineering mindset beyond pure QA automation.
