Oh, it's really simple. I am not
MBB material and I know very well I won't be one.
I was actually a regular for the first 5 years of my working life.
Anyway, I've worked long enough to know where I stand in life and it really doesn't matter. (e.g things like I should be a partner by XX years). Not all careers path starts with a degree from a branded university and goes smoothly. Mine included flying on a Super Puma to Horsburgh lighthouse, doing business in some third world Latin American country, mistaking their vice-president for the security guy (he walked into the lift without security and had that bundle of keys like the security guard hanging from his pants), dealing with some mayors in a third tier cities in China. So yeah, no issues with being a "manager".
Haven't got any regrets yet.
Anyway, back to the subject at hand, what is their structure like?
