Preparing for EY-Parthenon (Corporate Finance Interview)

Hey there!

Watch out! The more technical practices at Strategy and Transactions have specific interview formats that might vary by region (I know for a fact that a very similar role in Asia and Europe can have different interview types), as they sit at the intersection of Strategy Consulting and Financial Advisory/IB roles.

Apart from PEI/personal/experience questions, you can expect either:

1. A strategy consulting-style case, tailored to Corporate Finance (e.g., net working capital optimization, opportunity sizing and valuation, cash optimization, maybe M&A or PE). I have a few of these cases tailored specific for positions like the one you are applying to, and I specialize in Corp Finance prep -- feel free to DM me to get more info

2. A technical interview, closer to the qualitative questions in IB, with technical questions (e.g., WACC, hurdle rate, D/E ratio). I have never seen live modeling for these roles and I suspect they would tell you in advance if this were the case. 

3. A mix of the two above

Please, note that (1) and (2) require a different study plan, so double check with your recruiter. I would candidly ask your recruiter to avoid any misunderstanding; below, you can find an example email to send them.

Best,

Tom

Subject: Question regarding the upcoming interview format 

Hi Qwerty,

I hope you are having a great week.

I am reaching out as I am currently preparing for my upcoming interviews for the Associate position, and I wanted to quickly clarify the expected format.

I understand that the interview structure for the technical practices within Strategy and Transactions might sometimes vary by region. Aside from the standard personal and experience-based questions, could you let me know if the technical portion will lean more toward:

1. A strategy consulting-style case tailored to Corporate Finance (e.g., net working capital optimization, valuation, or M&A), or

2. A technical discussion focusing on qualitative corporate finance concepts (e.g., WACC, hurdle rates, D/E ratios)?

Knowing whether to expect one of these specific formats, or a mix of both, would be incredibly helpful so I can properly focus my study plan in the coming days.

Thank you in advance for your time and guidance!

Best regards,

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!

Hi Rada,

I strongly encourage you to reach out with the first two questions to the recruiter you've been in touch with regarding the first two questions. 

In practice, the process differs slightly between firms, offices and roles. So it's best if you get as much information as possible from the recruiter to then know how to adjust your prep process. 

If you don't manage to get a response from them, I recommend you try to:

• Familiarise yourself at least with the basic Corporate Finance terms (AI should be helpful here).
• Look at Corporate Finance cases in the case library
• Review the job description on their website to get an understanding of how much CF knowledge they expect you to have

If you need help preparing for the interview, please reach out. Otherwise, I'm sharing here another resource you might find helpful:

Best,
Cristian

Good progress — getting an extra round with Corporate Finance is usually a positive signal.

At EY-Parthenon, this step is typically to check whether you can operate comfortably in a deal / transaction context, not whether you’re a pure finance specialist.

1. What to focus on (and how deep)

You don’t need heavy modeling. You do need to be solid on fundamentals and logic:

• Valuation basics
  • DCF: what drives value (cash flows, growth, discount rate)
  • multiples: EV/EBITDA, P/E, when/why you’d use them
• Financial statements
  • how P&L, cash flow, and balance sheet connect
  • what drives revenue, costs, margins
• Cash & working capital
  • receivables, payables, inventory
  • how they impact cash (this comes up a lot)
• Deal logic
  • why companies do M&A
  • where value comes from (synergies, growth, cost savings)

Depth = you can explain it clearly and apply it, not build models.

2. How it differs from strategy interviews

Structure is similar, but:

• more numbers-driven
• more focus on feasibility and financial impact
• less abstract strategy, more “does this actually work financially?”

Cases might feel like:

• due diligence
• valuation discussion
• profitability with a strong finance angle

3. Questions you might get

Technical / semi-technical:

• “How would you value a company?”
• “What drives EBITDA?”
• “How does working capital impact cash?”
• “What would you look at in a due diligence?”

Fit:

• why transactions / corporate finance
• attention to detail
• handling pressure / tight timelines

4. Materials

Keep it light and practical:

• short YouTube refreshers on DCF / multiples
• basic accounting recap
• maybe skim a few M&A / due diligence cases

No need to go deep into textbooks.

How to approach it

Don’t try to become a finance expert in a week.

Your goal is:

• clear, structured answers
• solid intuition
• no obvious gaps on basics

Your strategy background is a plus — just show you can connect strategy to numbers.

If you want, happy to run through a mock or help you pressure-test typical questions — this type of interview is very trainable once you know what they’re looking for.
