Thanks for your replies. I've heard that your intern wage increases by 1 dollar every year. I'm curious: what if you've never worked as an intern before but you're in P2 year, do you get paid the wage of a P1 or a P2?
And I agree with that, it is fixed by company. The OP question asked if intern pay was the same "regardless of who hires you', and no it is not. Intern pay at Chain A may differ from intern pay at Chain B which may differ from intern pay at Hospital A which may differ from intern pay at Hospital B which may differ from intern pay at Independent Compounding Pharmacy A, etc.
