Unless you graduated from oxbridge or some other ivy league university it is close to impossible to work in one of the bulge bracket investment banks.

Unless you graduated with 1st class honors from our local unis (NUS/NTU/SMU), it is close to impossible to work in one of the local bank's investment banking dept.

So with a degree from RMIT it is near impossible to get into investment bank where fresh IB analysts draw a starting pay of ~$8000.

If you want to have a slim chance, you should start of under corporate banking or SME Banking and slowly hope to one day internal transfer to the IB side. Credit card/Personal banking or operations (worse in consumer banking) are on the totally opposite side of IB and will make it impossible for you to join even at a later date as its under the consumer banking instead of corporate side.
