Yes, I was with SCB before as a consumer banker, join them with exactly the wrong concept that doing these lousy jobs and long hours were the way to join PB/IB next time.

It's a myth. Many people are just hanging by hoping and praying, but in my 2 years there I never know anyone who actually succed in making the switch. All we had were rumours, but never an identifiable person with an actual name. The bank itself will always subtly imply the possibility to keep the grunts motivated and stay with them.

Base on my observation, to make it to these pulmp jobs, either you have sterling academics and join the FO right at the start, or you are some rich kid with rich connections or you are mid career who build up your connections in some other industry. Ammassing experience and network with the common masses who only have a few hundred k in their banks aint gona get you anywhere to IB.
