What is the scope of instrumentation & control engineering in NIT Trichy placement-wise?

Instrumentation and control engineering is a diverse field and will place you in many diverse jobs.
As far as NIT Trichy is concerned, considering only placement, ICE enjoys good placement to be considered in top 5 branches.
As a student of ICE, you can chose between software, electronics, core instrumentation and management jobs.
So if you are good and have got a descent CGPA, you won’t find any difficulty getting a job in some top companies.
I hope the answer helped.
