Hi Ankit,

There are two ways to apply in BARC for the engineering student. One is the training/projects domain another is the recruitment. For the training, only those students of B.E./B.Tech who have appeared 5thsemester and above can apply. For the recruitment, you have to appear in the GATE and secure marks above the cut-off to get yourself considered but this option is NOT possible in the 3rd year of your graduation. 
Hope that helps. 

Hi Ankit !!

You have two options to join BARC. The first is to appear for the GATE exam. The other is to appear for NPCL exam. Since you are a engineering student you are eligible to apply. It is a must to complete graduation. You cannot appear when you are in the 3 year. However you can do so when you reach the 4th year. Make sure that you have at least 50% marks in graduation. Also there is a minimum age requirement of 19 years. The upper age limit is 25 years. There are some relaxations in the rules for those from the SC/ST caste. Since you are in the third year you can start preparing for the exams.

Hope this helps
