I will answer this question with respect to ECE class of 2018. Average package this year was around 6 lac and 85% of students were placed till december 2018 and remaining got placed last semester. Apart from core companies students were placed in IT companies and Consulting firms.

The batch of 2017 saw 138 students from ECE getting placed in reputed companies like Infosys Tech, TCS, Texas Instruments, ST Microelectronics, Nagarro Software, NXP Semiconductors, Click Labs, JP Morgan, Deloitte Consulting and MU Sigma. Companies like MU Sigma, NXP Semiconductors, and Texas Instruments. There is no exact data about the package figures but it is evident that companies like MU Sigma, NXP Semiconductors, and Texas Instruments give decent packages ( ranging 5-7 lacs or even more), whereas mass recruiters like TCS and Infosys give somewhere 4-5 lacs initially. 
I hope it helps.
