I had joined Stc for selenium training. Ketan sir helped us alot while learning java and selenium concepts. I was not having any experience in java but Ketan sir explained all required java concepts and all the practice was hands on so I actually learned all concepts practically. If you are willing to switch in automation testing,and even if not confident about ur java skills do join stc. Framework topic which is not covered in many institutes but is covered in stc. Ketan sir will be there to help you even after ending your course. Also new job openings are informed by ketan sir so we can get desired jobs.
