What do NIT Trichy MCA students do for placements? Do they learn everything on their own?

It's pretty obvious that NIT Trichy MCA students or any student would probably study to get good placements. These students dont learn everything on their own as they are guided by the seniors during the initial months. Students are taught about the entire placement process from how to approach it and how to prepare for it. You will have to do a lot of self-study as well but many seniors conduct classes on competitive programming and other subjects. Students tend to clear their doubts and understand the basics better in these classes and the seniors are very helpful. 

Even as a first-year MCA student at NIT Trichy you won't feel lonely or lost for a second as the seniors offer constant assistance in the form of notes, papers, questions, and anything related to it. Some helpful seniors even conduct mock interviews for second-year or first-year students. However, you need to maintain good relations with your seniors in order to seek help from them. Ultimately, the seniors will only guide you and you alone have to climb the success ladder.
