Freshman IB Interview in 2 days - Need advice for preparing technicals

I just got notified of it yesterday. It's a phone call with an associate. I'm not sure if there will be technicals but might as well be prepared. Its a boutique in a big city (NY/CHI/LA). So far I've gone over DCF. I already knew the concepts but now I can do 5 years + perpetuity easy. I know how enterprise value and WACC works (somewhat). I took a semester of accounting so I can roughly tell you what happens to the three financial statements when you add $10 of depreciation expense and whatnot. What other topics should I go over? Comparables I'm confused on how to prep so advice on that would be appreciated. Anything else specifically? Would love some advice.

If you guys have any short & quick online resources too that condense all the info well I would really appreciate it. I've just been using google and WSP through my school so far.

I prepped behaviorals last night and came up with the BS stories so I should be good on that front as well.
