Dear friend,

From my point of view Electronics and Instrumentation is basically a hybrid branch, you can go 2 ways from here. Either you can go and work in a company fully on Electronics, or Instrumentation. But in contemporary these two have some uses in each of their field.

There are many Electronics companies in India,  many of them offer good packages. In case of Instrumentation, the opportunities are basically low in India. Because Instrumentation Engineers are demanded in most of the Oil & Refinary companies, which are very few, and are basically hire through GATE.

Hope this may help you.

Good luck !!!
