Hello Prathima,

The scope of IT branch is a lot in private sector. The placement of IT branch is also very good and you will definitely get a handsome salary. The companies you can opt for are:

• MICROSOFT
  
• GOOGLE
• APPLE
• FLIPKART
• INFOSYS
• WIPRO
• TCS

These are examples and many more companies like these.

Now talking about ISRO then the answer is yes you can get a job in ISRO as it requires engineering's from all the branches but there is a problem as the vacancies are less for CSE and IT students compare to mechanical and electrical.

I hope you will find my answer helpful.

All the best.
