It’s not underrated at all. When you’ll pass out you’ll realise the value of VIT tag.
If you happen to do a start-up after VIT you will realise investers know about VIT and as it happens they invest in people who have a good repo.
Graduates from Vit are working in the industry at high levels like google, Amazon, BIG4, Oracle and that association with your college helps whosoever graduates from VIT. So I would never say vit is underrated in any sense.
