If you are interested in CSE, choose VIT. It has a good computer science branch with a decent placement record. The salary packages offered for the branch ranges between INR 5-48 LPA. Students are usually recruited as software developers and web developers. TCS, Wipro, and Microsoft are among the major recruiters that frequent the placement drive.
BITS Goa is definitely better than VIT since the college itself is a brand and the placements are equally good.
When it comes to average placements, even for branches like civil, the placements are better in BITS and even greater than the average CSE ones at VIT. Companies that pay less than INR 4 lakhs per annum are not allowed on campus at BITS.
