To be honest both the universities are equally good in term of placement in both cse and ece. With top companies like Microsoft, Cognizant, TCS, GeeksforGeeks etc recruits from benett university , whereas companies like amazon, philips,HCL,LG, black rock recruits form amity noida. So placement wise both the universities provide good placements in both CSE and ECE.
