It depends on how you join Shell.
As a fresh graduates, minimum pay are rm4+++ with 2 adjustments a year. 1 year to confirm and next year is the important time for you to perform(in terms of work and office politics).
If you are selected, congrats, your path is like going to top floor using private elevator.
Else, you still can climb, but with a jam packed elevator, worst case, gets kicked out when time are bad.
If join with experience, the pay would be higher as a start but no 2 adjustments.
