The finance interview, explained
A complete guide to interviews in private equity, M&A and corporate finance: how the process works, how to prepare your motivation, the technical knowledge you need (financial statements and valuation), and the finance case types with fully worked examples.
The basics
What finance interviews test
Interviews for private equity, M&A and corporate finance roles test one core ability: can you assess a business from both a commercial and a financial angle? You form a view on how a company performs, how healthy it is, where the value comes from, and whether a deal or investment makes sense at the price on the table.
The emphasis shifts by role. M&A interviews lean more on detailed technical and valuation knowledge; private equity leans more on business judgement and investment thinking. In both, understanding the numbers and what they mean is the foundation everything else rests on.
The process
What a finance application looks like
Processes vary by firm, but most follow a similar path from application to offer. Each step screens for something different, so prepare for all of them, not just the technical round.
Motivation and fit
Preparing your motivation
A simple way to show genuine interest is to follow the market. Track a few recent deals you can discuss, know a valuation multiple or two for the sector, and read Dutch and international financial news. Interviewers can tell within a minute whether your interest is real or rehearsed.
Technical: financial statements
The three financial statements
Almost every technical question builds on the three statements. Know what each one shows, and, more importantly, how they connect.
How they link
Net income from the P&L flows into two places: the top of the operating section of the cash flow statement, and retained earnings on the balance sheet (less any dividend paid). On the cash flow statement, you add back non-cash items such as depreciation, adjust for changes in working capital, subtract capital expenditure, and account for debt and equity financing. The resulting change in cash updates the cash line on the balance sheet, and the balance sheet balances again. Being able to explain what happens to all three statements when a single line item changes, for example depreciation rising by ten, is a classic technical test.
Technical: valuation
How companies are valued
Three families of methods come up again and again: intrinsic (DCF), relative (trading and transaction multiples), and return-based (LBO). Know the mechanics, the inputs, and how to interpret each one.
The football field
Because each method gives a range rather than a single number, analysts plot the ranges side by side on a bar chart known as a football field. It shows where the methods agree and disagree. Transaction multiples usually sit at the high end (control premiums and synergies), the DCF lands mid-range, and the LBO often marks the floor.
Enterprise value vs equity value
Enterprise value is the value of the whole business, funded by both debt and equity. Equity value is what remains for shareholders. The bridge is simple to state and often tested: equity value equals enterprise value minus net debt, plus or minus a few adjustments such as minority interests and non-core assets. Confusing the two is one of the most common technical slips.
Feeling for financials
Reading the numbers like an investor
Beyond mechanics, interviewers want to see that you can look at a set of financials and quickly form a view: what kind of business is this, and how good is it? Two habits help: knowing typical margin profiles by sector, and linking financial patterns to what they imply about the business.
Typical margin profiles by sector
| Sector | Gross | EBITDA | Capex | What the pattern signals |
|---|---|---|---|---|
| Subscription software | 70%+ | 20-40% | <5% | High gross margin, low capital needs, large deferred revenue and often negative working capital. |
| Industrial / manufacturing | 30-50% | 10-20% | >10% | High capex and large inventories; working capital swings with the cycle. |
| Retail | 20-40% | 5-15% | ~5% | Thin margins on high volume, high inventory, and often negative working capital as suppliers finance the business. |
| Professional services | Mostly staff | 10-25% | Low | Asset-light; the main cost is people, and utilisation and day rates drive the margin. |
Ranges are broad rules of thumb to build intuition, not precise figures for any specific company.
Judging business quality from patterns
| Pattern | What it might indicate | Follow-up question |
|---|---|---|
| Stable EBITDA margin but weak free cash flow | Capex or working capital is draining cash | Can cash still cover debt service and growth plans? |
| Revenue flat, margin improving | Cost control or genuine efficiency gains | Is it sustainable, or one-off cuts? |
| High revenue growth, falling margins | Growth is being bought with discounts or opex | Is the company scaling inefficiently? |
| Working capital rising as a share of revenue | Weak collections or inventory building up | Is cash getting tied up in receivables or stock? |
| Falling interest coverage | Rising leverage or falling EBITDA | Could this become unsustainable in a downturn? |
Case types
The four finance case types
Most finance cases are a variation on four types. The worked examples that follow are original and use invented companies and numbers; they show the method, not any real deal.
Worked example 1
Business sense: read the financials
Prompt: You are handed a simplified P&L and balance sheet for an unnamed company. Gross margin is about 80 percent. There is a large deferred revenue balance on the liabilities side, very little property or equipment, and negative operating working capital. Sales and marketing and research and development are the two biggest cost lines. What kind of business is this, and what do the financials say about its quality?
How to approach it
Read the pattern, do not just list metrics. An 80 percent gross margin with almost no physical assets points to software or another digital business rather than anything that makes or moves goods. Large deferred revenue means customers pay up front, which is the signature of a subscription model and explains the negative working capital: customers fund the business before it delivers. Heavy sales and marketing plus research and development is the classic cost shape of a software company investing in growth and product.
A structured conclusion
This is most likely a subscription software (SaaS) business: asset-light, high gross margin, recurring revenue billed in advance, growth funded partly by customer prepayments. On quality, the key question is not the gross margin, which is high by design, but whether the sales and marketing spend pays back: does the business keep its customers (low churn) and earn back its acquisition cost quickly? Watch the gap between profit and cash, and whether growth still needs ever more marketing to sustain it.
Worked example 2
Business sense: build a P&L
Prompt: Build an illustrative P&L for a chain of forty low-cost, largely unstaffed fitness clubs. What are the main lines, and roughly what margin would you expect at maturity?
How to approach it
Start with revenue as a driver tree: members per club, times an average monthly fee, times twelve, times the number of clubs. A budget club might carry a few thousand members at a low monthly fee. Because a gym sells access rather than goods, there is little classic cost of goods sold; it is cleaner to work down from revenue through direct site costs to a site-level result, then subtract central overhead.
Illustrative P&L shape (per year)
The key drivers to name out loud: membership penetration in each catchment, price and churn, and rent as a share of revenue. A mature, well-located club earns a healthy margin because the model is largely fixed-cost; a club still filling up earns much less, so the blended margin depends on how many clubs are ramping. Always state your assumptions and be ready for the interviewer to challenge them.
Worked example 3
Paper LBO: estimate the return
Prompt: A private equity fund is looking at a last-mile parcel-delivery company with 150 million euro of revenue and a 20 percent EBITDA margin, so 30 million euro of EBITDA. It would pay 9 times EBITDA and fund the deal with 5 times EBITDA of debt. Assume EBITDA grows 8 percent a year, the fund exits after five years at the same 9 times multiple, and, to keep it simple, ignore interest, tax, capex and working capital so that the debt is repaid from exit proceeds. What are the rough IRR and MOIC?
1. Structure the entry
2. Grow EBITDA over five years
3. Exit and returns
All figures in millions of euro. Numbers are invented to show the method.
What drives the answer
Three levers create the return: operational improvement (EBITDA growth), deleveraging (using cash flow to pay down debt), and multiple expansion (exiting at a higher multiple than entry). Here only growth does the work, since the multiple is flat and we ignored cash paydown. It helps to memorise a few MOIC to IRR anchors over five years: roughly 1.5x is about 8 percent, 2.0x about 15 percent, 2.5x about 20 percent, and 3.0x about 25 percent. In a real deal you would add interest, tax, capex and yearly debt amortisation, which lowers the return but makes it realistic.
Worked example 4
Investment decision: invest or pass
Prompt: A private equity team is screening a private-label snack manufacturer in Western Europe, pitched as a buy-and-build platform. Revenue is 90 million euro, up from 75 million two years ago, but EBITDA is 10.8 million (12 percent), down from 12 million (16 percent). Two retail customers account for about 60 percent of revenue. A new production line pushed capex to roughly 9 percent of revenue, so free cash flow is thin. The owners want about 11 times EBITDA. Would you invest, what are the key risks, and what would you diligence?
The case for it
- Top line is growing and private label has a structural tailwind.
- Fragmented sector, so a buy-and-build roll-up could genuinely work.
- Manufacturing base and retail relationships are hard to replicate.
Red flags
- Margin fell from 16 to 12 percent even as revenue rose: something is wrong.
- 60 percent of revenue in two customers is heavy concentration risk.
- Capex near 9 percent leaves little free cash flow to service debt.
- 11x for a margin-deteriorating asset looks rich.
Decision and diligence
On balance this is a likely pass, unless diligence clearly explains the margin drop and shows a credible path to recovery. The market is sound and the roll-up logic is real, but a leveraged deal needs dependable cash flow, and here both the margin trend and the customer concentration threaten it, at a full price. The questions to raise: what actually caused the margin decline, input costs or pricing pressure from those two customers? How sticky are the big contracts, and on what terms? Is the new production line ramping, so capex will normalise, or is high capex structural? And can management realistically execute a buy-and-build plan? A decisive answer with clear reasons matters more than a hedged one.
Worked example 5
Strategy case: create value before exit
Prompt: A fund owns a mid-sized chain of fitness clubs and wants to grow its value over the three years before it sells. How would you approach it?
Structure it around the value levers
Frame the answer with the three ways a private equity owner creates value, then focus where you can actually move the needle. Operational improvement is the main one here. On revenue: open clubs in under-served catchments, raise price where churn allows, and add ancillary income such as personal training or retail. On margin: renegotiate rent, improve energy efficiency, tune the low-staff operating model, and centralise procurement across clubs. Deleveraging happens quietly as the clubs generate cash and pay down debt, and multiple expansion can come from scale, a cleaner brand, and a more predictable, recurring membership base.
Land it with a prioritised plan
Finish with a clear recommendation: a short, prioritised plan for the first hundred days (quick wins on rent and pricing), the bigger multi-year moves (new clubs, ancillary revenue), and a clean equity story to present at exit built on unit economics, recurring revenue and a credible growth pipeline. State the main risk, for example that aggressive price rises lift churn, and how you would monitor it.
Do's and don'ts
How to handle the interview itself
Finance interviews test more than analysis. They test how you handle pressure, defend assumptions and stay structured when challenged. Much of the real assessment happens in the back-and-forth after you present.
Do
- Lay out your structure on paper before you calculate.
- State every assumption out loud and sanity-check multiples and margins.
- Keep the difference between enterprise value and equity value straight.
- Be decisive: give a clear invest-or-pass call with reasons.
- Think out loud and, if stuck, ask for a moment to work it out.
Don't
- Jump to a conclusion after reading a single statement.
- List metrics without saying what they mean for the business.
- Get lost in detail and lose the big picture.
- Change your answer every time the interviewer challenges you.
- Forget to interpret the IRR and MOIC once you have them.

FAQ
Frequently asked questions
What do finance interviews test?
They test whether you can assess a business from both a commercial and a financial angle. M&A interviews lean more on detailed technical and valuation knowledge, while private equity leans more on investment judgement, but both expect you to read the numbers and understand what they mean.
Do I need to build a full LBO model?
For most junior interviews, no. You need to understand the mechanics and be able to do a paper LBO by hand, estimating IRR and MOIC from a few inputs. Full modelling tests usually come later in the process or in dedicated case rounds.
Which technical topics come up most?
The three financial statements and how they link, the main valuation methods (DCF, trading and transaction multiples, and LBO), the difference between enterprise value and equity value, and reading margins and cash flow to judge business quality.
What is a paper LBO?
A simplified leveraged buyout you solve on paper. From a purchase price, leverage, growth and an exit multiple, you estimate the return (IRR and MOIC). It tests whether you understand the mechanics and can do quick, structured mental maths under time pressure.
What is the difference between M&A and private equity?
M&A advisers help clients buy, sell or merge companies and earn a fee per transaction over weeks to months. Private equity firms buy companies with a mix of equity and debt, improve them over roughly five to seven years, and sell them for a return on capital.
How is enterprise value different from equity value?
Enterprise value is the value of the whole business, including both debt and equity. Equity value is what is left for shareholders after subtracting net debt and a few other adjustments. The bridge between them is the classic enterprise value to equity value walk.
How much mental maths is expected?
Enough to work without a calculator: growth rates, margins, multiples, ratios and multiplying large round numbers. It helps to memorise a few MOIC to IRR anchors so you can convert a return over five years in your head.
How do I prepare in a few weeks?
Learn the three statements cold and how they connect, drill valuation and a handful of paper LBOs, practise reading financials and investment cases out loud rather than in your head, and follow a couple of recent deals you can discuss in a fit interview.
