Hey,
There isn’t any major difference between Pilani and Goa campuses.
Major companies are invited to the three campuses at the same time. So, all students get similar opportunities.
The kind of placement the student yields, depends strongly on his/her technical skills. I don’t think it depends on he/she being from Pilani, Goa or Hyderabad.
Generally Pilani campus students get better placements because of them being more talented. However, there is no big difference.
Cheers,
