Houlihan Lokey Financial Advisory Services (FAS) Financial Valuation Advisory (FVA) Portfolio Valuation (PVAL) technical interview

After completing an HR screening which wasn't really much of a screening but discussion about the group and the bank, what the candidate process would be like, with the implication that the next stage of a technical assessment as a forgone conclusion. 

I've scheduled the technical assessment and asked as to what the scope/focus would be, which the response was that there was a written segment and an excel based technical segment covering "basic portfolio valuation concepts"

Does anyone have any experience with the technical interviews for this specific group at HL? Will the scope be traditional corporate finance as in arriving at enterprise/equity valuations based on a combination of DCF and multiples? 

The job description details valuation of illiquid debt and equity positions. Anyone have any resources on the basics of illiquidity discounts? 

Beyond calculating enterprise value and barring any distress (and a fulcrum credit) or dramatic changes in interest rates, would some illiquidity discount be applied to the face/par value of any bond positions?

This is a little bit of new territory for me. Appreciate any replies, thx.
