Does Nit Rourkela placement cell allow civil engineering students to sit for computer science engineering placement?

It is not that NIT Rourkela placement cell does not allow Civil Engineering students to sit for CSE placements. The thing is that most software companies that visit the campuses with SDE roles do not allow other branches to sit for their placements. I assume by CSE placements you are referring to IT companies.

Certain top companies like Microsoft, Google, Goldman Sachs and Mathworks allow students from all the branches to sit for their placements. But for most software companies, branch is one of the criteria to filter out those students who can apply. Also, they mostly prefer students from CSE and circuital branches like EI, EC and EE. 

The reason being that students from these branches work with codes more often and are well-versed in programming languages. The same is imperative for working in IT companies. However, it is also true that many students in other branches love to code and wish to work in these IT firms.

NIT Rourkela has no control over the criteria set by various IT companies and you will have to check the same before planning to sit for the placement of any IT firm.
