Mathematical areas to be covered prior to interview...

[soosta]

I am considering applying for various trainee trading positions within prop/smaller houses, basically not the big IB's. I've read that trading styles employed are radically different in these two different institutions, so would the math required be different to succeed in the job?

I was wondering what kind of math would I need to be sharp on in order to succeed in the interview test but most importantly the job?! I hear probabilities are an important topic for example.

Thanks.
