Since Gayatri is a private engineering college the placement department pays more attention when a company wants to come to the campus for a drive. The college tries it's best to bring the companies to their college. But AU on the other hand is a government college so the recruiters visit the campus on their own interest and keeping in mind the reputation of Andra university. So we can say that Andhra university is a brand. But in none of these colleges core placements are appreciable. So we can talk about only IT recruiters that too service based mass hiring ones such as Infosys,TCS , Wipro etc. In Gayatri TCS is the day 1 company which hires students in bulk from all the branches, where as Infosys is bulk recruiter in AU. Amazon has also visited gvp for 2017 placements and it has hires 3 members from CSE department with a package of 14 lpa. So if you want to choose CSE Gayatri will offer many opportunities as these people get more than one offer. But if u opt for any other core branch there is no comparable difference between gvp and AU and in that case one may opt AU as it is very reputed and its certificate too is valuable.
