I have a choice between IT (Information Technology) in NIT, Surathkal and CS (computer science) in RVCE, Bangalore. Which one would be a better choice in terms of placements, Brand name etc.??

Between the options, you should choose NIT Surathkal IT. Here are the reasons why. 

• The syllabus difference between IT and CSE is not so much in this institute.
• The placement process in the institute is exceptional, specifically for the circuit branches, including IT, CSE, ECE, and EEE. However, in the last year, students are recruited by Google and Microsoft.
• NITK has its own brand name. Maybe it is an NIT, but the students here get a lot of exposure. JEE Mains toppers mainly take admission in this institute every year.

Here is a full overview of NIT Surathkal

You will have to stay here in the hostel, which provides a good experience for them. During the tenure of the course, you will learn how to take care of yourself. Also, if your hometown is Bangalore, then you can frequently visit home.
