Preparing for EY-Parthenon (Corporate Finance Interview)

Question

I’ve recently passed several interview rounds for a Strategy & Transactions role at EY-Parthenon. I’ve now been invited to an additional interview with their Corporate Finance practice.

My background is primarily in corporate strategy, and I don’t have deep experience in corporate finance. I’m trying to understand how best to prepare for this interview.

Specifically:

What topics or concepts in corporate finance should I prioritize for this type of interview? (e.g., valuation, financial modeling, accounting basics)? How deep?
How different should I expect this interview to be compared to strategy-focused case interviews? What fit / technical questions they can ask?
Are there any recommended materials (books, YouTube channels, etc.)?

Any guidance from people who have gone through similar interviews or worked in Corporate Finance at EY-Parthenon would be really helpful.

Many thanks!

Hi! First off, massive congrats on making it this far!!

what to expect and how to prepare:

1. What to prioritize & how deep? Since your background is in strategy, they know you aren't an ex-Investment Banker. They won't expect you to build a complex LBO model from scratch on the spot. However, your accounting fundamentals and basic valuation knowledge need to be rock solid

The 3 Statements: You absolutely must know how the Income Statement, Balance Sheet, and Cash Flow Statement link together
Valuation: Understand the core mechanics of a DCF (especially WACC and Terminal Value) and Comps/Multiples

2. How different is it from a Strategy case? Corporate Finance cases ask "Is this target company fairly valued?" or "Does this M&A deal make financial sense?". Also, expect rapid-fire technical questions rather than just broad frameworks. A classic fit/tech question is: "If depreciation goes up by $10, walk me through the impact on the 3 financial statements."

3. Recommended Materials skip the heavy academic textbooks; you need practical, interview-focused prep.

M&A / Breaking Into Wall Street: Search for their "400 Investment Banking Interview Questions" guide It is the absolute gold standard for mastering technical and accounting questions
Corporate Finance Institute (CFI): Their YouTube channel is amazing for quick, visual refreshers on DCF mechanics and accounting basics

Lean into your corporate strategy background for the "commercial" side of the case (market trends, synergies), but make sure your basic financial math checks out. Best of luck!
