I applied through college or university. The process took 1 day. I interviewed at Equifax (Mumbai) in Jan 2019
Interview
First round was aptitude test. Very easy questions and was pen paper type. Second round was GD. Third round was Technical interview. You should be thorough with each and every line in your resume because they ask in very much details. Fourth round was HR. In this round also they ask about your projects and basic HR questions.
It was a good experience. The people who conducted the interview were all kind and patient and encouraging. Questions asked were of medium level and spanned various topics that we learn throughout the btech course.
