Less than 1 year at BB M&A: is this enough to learn sufficient technical skills? When does the learning curve start to drop?

Hi fellas,

For ex and current bankers out there:

How long were you on the job before you could put together a model with reasonable comfort? By reasonable comfort I mean without constant supervision/question asking. i.e. no late nights wondering why the fuck your BS doesn't balance, or googling how to enable circular references for debt and interest etc.

Being a non-finance student, I am still at that stage where I wouldn't feel too confident if someone gave me 3 days to bang out a functional three statements and a dcf/lbo.

After say, 10 months on the job, would you be reasonably comfortable with this? How much left is there to learn in your second year?

If, say, someone wanted to jump to MM PE after 1 year, would they be technically savvy enough to handle the job?

Appreciate the input!
