Both Vel Tech and LPU are reputed institutes. Choosing one of these two institutes depends upon whether you want to join in North India or South India.
Placements are quite good for ECE, CSE, EEE, and Mechanical branches in Vel Tech. In 2020, the highest CTC offered in the placement drive was 10 LPA. Major recruiters that visited the placement drive were Infosys, Byjus, Capgemini, Amazon, etc.
You should note that in India other than IITs, NITs, or BITS Pilani, the other engineering colleges don’t put that much effort to enhance the skills of the students. So, you will need to make effort by yourself irrespective of which institute you choose Ve Tech or LPU.
