Private M&A vs Public M&A interview technicals

Hi,

Having downloaded the WSP financial modelling course, I noticed much of the course focuses on equity value derived from share price and shares o/s, as well as EPS and accretion/dilution.

I am interviewing for an analyst role at a boutique MM IB in London which primarily does private/PE-backed deals - to what extent is accretion dilution relevant and what technicals are more likely to be tested in the interview that relate specifically to private M&A?

Thanks
