You might know that MECHANICAL, ELECTRICAL and CIVIL are the only core engineering branches. So the advantages of being into core branch is that they have more opportunities in government sector. Thr jobs you can opt in ELECTRICAL in government sector are:

• BHEL
  
• GAIL
• ARMED FORCES

I hope you will find my answer helpful.

All the best.
