There is a scope of Computer networking in India but it is not that developed. Datacom field has good scope.

Top companies in this field is CISCO Ericsson, Huawei, Samsung R&D, TATA Communications, Nokia/Alcatel Lucent, Oracle and Reliance Jio.

Campus placements in this field is less. You have to gain experience in order to get a good job.

Good Luck!!
