World Bank career progression through the YPP. What grade level (rank) can one realistically reach at the world bank if they are selected through the YPP at the age of 32?

I have been considering of making the World Bank senior professional roles as my goal. To get a rough estimate I was wondering What grade level (rank) can one realistically reach at the world bank if they are selected through the YPP at the age of 32? Or in other words, What rank do most people reach at WBG if they join through the YPP?
