As one of my friends is a student of REVA University, I might be able to provide some information about it.

• The faculty members of REVA University are extremely helpful and highly experienced in their particular field. 
• The environment here is very disciplined and has an excellent learning atmosphere. 
• The CS department organizes workshops for better learning.
• The placement here is not the best but is improving very well. If proper education is provided the students will be able to secure a good job offer even in off-campus placements.
• Considering hostels, REVA University has one of the well-maintained hostels in the country.
• The food provided is good, healthy, and affordable. 
• Other facilities like a laundry facility are available at INR 100 per year.

But like everything else it has its flaws which bother the students. This includes the wifi facilities which are not great as in the hostels most of the times the connection is interrupted.
