Many people here seem to think that you basically reach partner and that's it.

No! Generally there are 5-8 levels of partners across the big 4 and the pay differs widely. If you are at the entry level partner level 200-250k all-in is quite common.

The very senior ones will of course hit above 1 mil, but those tend to be executive level, I don't think there is any local executive in any of the big 4 based in SG now, a couple of caucasian expats at most.
