Hi Siddharth,

IES Indian Engineering Services conducted by UPSC that is Union Public Service Commission. Yes every engineering students are eligible for IES exam. Students with computer science branch are also eligible for giving the exam. To apply for IAS exam candidate age should be between 21 years to 30 years. But IES have only four branches in it and they are as follows.

1) mechanical engineering

2) electrical engineering

3) electronics and telecommunication engineering

4) civil engineering

So you need to select one of these as your course for IES.

I hope your operation has been answered properly.

All the best for your future!
