Hi Karnam

Aeronautical Engineeing is has placements only in HAL, ISRO like organizations and have to face stiff competetion to get selected in these. But in ECE, there are many companies like HCL, Airtel, Vodafone, Jio, TCS etc who recruit the people.

Moreover in future, ECE will be expanding more and more due to advancement in technologies and Digital India Mission.

Hope this helps you. :)
