Dear candidate, branches which have maximum scope in government jobs are:

• Mechanical Engineering
  

• Electrical Engineering
  

• Electronics and Communication Engineering
  

• Civil Engineering
  

• Electrical and Electronics Engineering
  

• Chemical Engineering
  

• Biotechnology
  
  

However, government jobs are reducing day by day so, many students of these branches start coding  to get private jobs of Computer Science Engineering.

Hope, it helps!
