Hi , Many companies come ,big four,TCS, Infosys,ITC,Govt Companies,IT companies…..long list.
Salary will differ based on your ranks, attempts.Rankers 12–18 lakhs package,
First attempt 9–12 lakhs,others 6–9 lakhs.This was in Feb 2018
I suggest you do also try offcampus .First day of campus ,you may be shortlisted to attend their interview by big four even though you take attempts ,but they will ignore you in interview after seeing your multiple attempts.You may feel disheartened if you take attempts and attend first day of campus,no company will take interest in you.Second day and third day of campus you will get opportunities. But always try off campus before hand,you will always get a better deal.
Please note ,this is my personal experience and may not be true for al campus centres
