CTS came to our college[On-campus]. There were 3 rounds. First was the aptitude round, which was very easy, questions came from distance and direction, logical,etc. Second round was technical interview but they asked only few technical questions(this depends on the role they are recruiting for, in my case they were recruiting for IT Services.So, I didn't get any serious technical questions). The Third round was the HR round they asked for my Self Introduction and a few words about my city and they asked whether I am time and location flexible. And that's it. The whole process was pretty easy.
