How private equity interviews differ from banking interviews

Three things change when you move from investment banking interviews to private equity ones. First, the timing is stranger. Mergers & Inquisitions describes the “on-cycle” process for analysts at large New York banks interviewing with the biggest funds: it starts and finishes within several months of your start date at the bank, it moves earlier every year, and interviews at the largest firms can begin and end within 24 to 48 hours. Off-cycle recruiting, for everyone else, is less structured, runs over months, and weighs your actual deal experience far more heavily. Second, headhunters gate the on-cycle process, so the first “interview” is often a screening meeting with a recruiter who decides which funds see your resume. Third, and most important, you will be asked to build or walk through an LBO. Banking interviews test whether you understand models; private equity interviews test whether you can produce one under time pressure.

M&I also makes a point worth internalizing: for most candidates, winning the interviews is harder than passing them. You do not need to be a math genius. You need the recruiting mechanics, a clean deal story and a paper LBO you can do half-asleep.

The six case formats you might be given

M&I catalogs six kinds of case study and modeling test, and knowing which one a firm uses tells you what to practice.

Ask the headhunter or your contact at the firm which format they use. They will usually tell you, and preparing the wrong one is the most avoidable way to fail.

Fit and background: the five questions that open every interview

1. Why private equity?

What it tests: whether you understand the difference between advising on deals and owning the outcome. Framework: contrast the two honestly. In banking you execute a transaction and move on; in private equity you underwrite a view with the firm’s capital, live with the company for years, and are judged on the return. Give one moment from a deal where you found yourself caring more about whether the business was a good investment than about closing, then say why the longer time horizon and the operating involvement suit you. Avoid “better hours” and “carry”; every interviewer has heard both.

2. Why our firm?

What it tests: preparation and fit with the strategy. Framework: know the fund size, the check size, the sectors, two or three portfolio companies, and one recent deal you can discuss. Then connect that to you: a sector you have worked in, a deal type you have executed, a style (operational, buy-and-build, growth) that matches your interests. Growth Equity Interview Guide’s version of the follow-up is sharper: “which of our deals do you like, and which do you not?” Have an answer to both halves.

3. Walk me through a deal you worked on

What it tests: whether you understood the transaction or just formatted the pitch book. This is the most important fit question in private equity, and M&I treats deal experience as its own interview topic. Framework, for each deal: the company and what it does in one sentence; the transaction (buyer, seller, price, multiple, financing); the investment thesis or strategic rationale; the two or three issues that actually mattered in diligence or negotiation; the outcome; and your own view, in hindsight, of whether it was a good deal and what you would have paid. Prepare two deals to this depth. If you were staffed on nothing that closed, pick the most advanced process you touched and be honest about the stage.

4. Would you invest in the company from your deal? At what price?

What it tests: the investor mindset. Framework: a real answer names the key value drivers, the biggest risk, and a price with a reason (“at 9x I get to a 20% IRR with modest growth; at 11x I would need margin expansion I do not believe in”). It is fine to say you would pass; passing with a reason is a better answer than investing without one.

5. Tell me about a time you disagreed with a senior person, or made a mistake on a deal

What it tests: whether you can push back on a deal team and own errors, both of which small investment teams need. Framework: situation, what you did, what happened, what changed. Choose a real mistake with a real consequence (a model error caught late, a diligence item missed) and spend most of the answer on how you fixed it and what you do differently now.

LBO technicals: the five questions every fund asks

6. Walk me through an LBO

What it tests: the whole structure, in order. Framework: set the purchase price (an EBITDA multiple) and the sources and uses: how much debt the business can carry, how much equity the sponsor contributes, and fees. Project the company’s operating performance and free cash flow, which is EBITDA less cash interest, cash taxes, capital expenditures and any increase in working capital. Use that free cash flow to pay down debt each year. At exit, apply an exit multiple to final-year EBITDA to get enterprise value, subtract the remaining debt to get equity value, and compare it to the equity invested to compute the multiple of money and the IRR. Then name the three sources of return, which is question 8.

7. What makes a good LBO candidate?

What it tests: whether you can look at a business as a lender and an owner at once. Framework: strong and stable free cash flow to service debt; a steady track record so lenders will lend; low capital expenditure and working capital needs; a defensible market position and recurring or contracted revenue; a good management team, or one that can be replaced; identifiable operating improvements; a reasonable entry price; and a credible exit. Growth Equity Interview Guide lists the same set and adds that a strong management team is not always required, because some firms specialize in replacing it.

8. How does a private equity fund make money on a deal?

What it tests: whether you can decompose a return. Framework: three levers. EBITDA growth (revenue growth and margin improvement), which raises the exit value; multiple expansion, selling at a higher multiple than you paid, which is the least controllable lever and the one interviewers distrust; and debt paydown, using the company’s cash flow to reduce debt so that more of the exit enterprise value belongs to the equity. A strong answer adds that the best deals are underwritten on the first and third levers and treat the second as upside.

9. What is the difference between IRR and multiple of money, and what is a good return?

What it tests: the mental math you will need in the paper LBO. Framework: the multiple of money (MOIC) is exit equity divided by invested equity and ignores time; IRR is the annualized rate that connects the two and depends on the holding period. The approximations worth memorizing for a five-year hold: 2.0x is roughly a 15% IRR, 2.5x roughly 20%, and 3.0x roughly 25%. Doubling your money in three years is about 26%; in four years about 19%. Most buyout funds underwrite to a 20%-plus IRR and a 2.5x-plus multiple, with the exact target depending on the fund and the risk of the deal.

10. How much debt can a company take on in an LBO?

What it tests: the capital structure side. Framework: it is set by the lenders, not the sponsor, and expressed as a multiple of EBITDA that moves with the credit cycle, the industry and the stability of cash flows. The structure is layered: senior secured bank debt (cheapest, first claim, amortizing), then subordinated or high-yield debt (more expensive, fewer covenants), with the sponsor’s equity beneath it all. Be ready for the follow-ups: what covenants are, why a company with volatile cash flows gets less leverage, and what happens to the equity return when leverage rises (it rises, along with the risk of default).

The paper LBO: a worked example you can do without a calculator

This is the question that decides most private equity interviews, and it is the reason the page exists. GEIG describes the format: 10 to 20 minutes, no calculator or Excel, numbers rounded to the nearest $5 million, growth assumed to be linear, and only EBITDA and free cash flow to construct each year. Wall Street Prep breaks the exercise into the same five steps we use below: assumptions, sources and uses, forecast, free cash flow, and exit returns.

11. Walk me through a paper LBO (the prompt)

Step 1, sources and uses. Purchase price is 10 times $100 million, or $1,000 million. Debt is 5 times EBITDA, $500 million. Equity is the remainder, $500 million. Say these out loud before doing anything else; interviewers want to hear the structure.

Step 2, the forecast. EBITDA runs $110, $120, $130, $140 and $150 million across years one to five. Interest is 8% of $500 million, or $40 million a year; in a paper LBO you hold it constant rather than recomputing it on a falling balance, and you say that you are simplifying.

Step 3, free cash flow each year. EBITDA less depreciation gives EBIT; less interest gives pre-tax income; less 25% tax gives net income; add back depreciation and subtract capital expenditures (which cancel here) to get free cash flow. Year one: EBIT $90, pre-tax $50, tax $12.5, net income $37.5, free cash flow $37.5 million. The same logic gives $45, $52.5, $60 and $67.5 million in years two through five. Total free cash flow over the hold: $262.5 million.

Step 4, debt paydown. All free cash flow goes to repay debt, so ending debt is $500 million less $262.5 million, which is $237.5 million.

Step 5, exit and returns. Exit enterprise value is 10 times $150 million, or $1,500 million. Subtract the remaining $237.5 million of debt for exit equity of $1,262.5 million. Divided by the $500 million invested, that is a multiple of about 2.5x. Over five years, 2.5x is roughly a 20% IRR (the exact figure is 20.4%). Then add the one sentence that separates a good answer from a complete one: “About $260 million of the roughly $760 million gain came from debt paydown and the rest from EBITDA growth, with no multiple expansion, so the return is not relying on the exit market.”

12. What is the most you would pay for this business?

What it tests: whether you can run the paper LBO backward. Framework: state the target return (say 20% IRR, about 2.5x over five years), hold the exit and the cash flows constant, and solve for the entry equity that produces it. In the example, exit equity of roughly $1,260 million divided by 2.5 gives about $505 million of equity, so at 5x leverage the answer is around 10x; at a 3.0x target you could pay only about $420 million of equity, roughly 9.2x. Show the logic, not just the number.

13. How would the return change if the hold were seven years instead of five?

What it tests: IRR intuition. Framework: the multiple of money rises (two more years of EBITDA growth and debt paydown) but the IRR usually falls, because the same or slightly higher multiple is spread across more years. Say which direction each metric moves and why. The follow-up is often the reverse: a quick flip at the same multiple produces a spectacular IRR on a small dollar gain, which is why funds look at both numbers.

14. How does a dividend recapitalization or an add-on acquisition affect returns?

What it tests: the toolkit beyond the base case. Framework: a dividend recap has the company borrow more and pay the sponsor a dividend mid-hold; it returns capital early, which raises IRR, but it adds leverage and risk and does not create value in the business. An add-on acquisition bought at a lower multiple than the platform trades at raises blended EBITDA and, if the combined company sells at the platform multiple, creates value through multiple arbitrage plus any synergies. Both are common; both have a downside you should name.

15. Why do private equity investors use EBITDA multiples rather than price-to-earnings?

What it tests: whether you understand what changes when you buy the whole company with debt. Framework: EBITDA is capital-structure neutral: net income is depressed by the interest on whatever debt the company happens to carry today, and the sponsor is about to replace that capital structure entirely. EBITDA also approximates cash flow before financing, which is what services the new debt. GEIG makes the same two points, adding that the items excluded from EBITDA are often non-cash. The weakness, which you should volunteer, is that EBITDA ignores capital expenditures, so for capital-intensive businesses investors look at EBITDA less capex as well.

Deals, markets and judgment: the five that show you think like an investor

16. Pitch me an LBO target

What it tests: sourcing instincts. Framework: a public company or a known private one, in a sector the firm invests in, with the characteristics from question 7. Give the business in one sentence, why it fits an LBO (cash flow, low capex, room to improve), a rough entry multiple and leverage, the thesis for creating value, the biggest risk, and the exit. Two minutes. Prepare two, one of which should be in the firm’s sector.

17. Which industries make good or bad LBO candidates, and why?

What it tests: pattern recognition. Framework: good: businesses with recurring revenue, low capital intensity and fragmented markets (business services, software with mature customers, healthcare services, consumer staples, industrial distribution). Bad: highly cyclical or commodity-exposed businesses, capital-intensive ones, and anything with technology or regulatory risk that could impair cash flow during the hold. Name one exception to show judgment; some funds do very well in cyclical industries by buying at the bottom.

18. What would you look at in diligence, and what is in a CIM?

What it tests: process knowledge from the buy side. Framework: a confidential information memorandum is the seller’s marketing document: business overview, market, financial history and projections, management, and the growth story. Diligence is the process of testing every claim in it: quality of earnings (are the adjustments to EBITDA real), customer concentration and churn, unit economics, the credibility of the projections, management references, and the legal and tax structure. Say which two items you would spend the most time on for the deal in question 3.

19. What do you think about the current environment for private equity?

What it tests: whether you follow the industry. Framework: have a current view on the cost and availability of debt (which sets how much leverage deals can carry), on entry multiples versus exit expectations, on the exit market (IPO and strategic buyer appetite), and on where the firm’s strategy sits in that picture. Read the last month of deal news for the sector before the interview; specifics beat generalities.

20. A brainteaser or a quick mental-math question

What it tests: composure. Wall Street Oasis’s free question set includes a handful of logic puzzles, and M&I files brainteasers under things not to worry about. Framework: restate the problem, structure it aloud, use round numbers. The mental math that matters is the paper LBO arithmetic: percentages, multiples, and the IRR approximations in question 9. Practice those until they are reflexes.

How to prepare: a four-week plan

1. Week 1: deal stories and fit. Write up two deals to the depth of question 3, including your own view on price. Draft answers to questions 1, 2 and 5 and rehearse them aloud.
2. Week 2: the paper LBO. Do the worked example above from memory, then change one assumption at a time (leverage, growth, exit multiple, hold period) and redo it until every variant takes under ten minutes. Learn the IRR approximations.
3. Week 3: timed Excel models. Build a full LBO from a blank sheet in under two hours, then in under one. This is where structured modeling tests earn their price; the WSO Private Equity Interview Course includes nine LBO modeling tests in the formats funds actually use.
4. Week 4: firm-specific work and mocks. Portfolio, recent deals, two LBO pitches, a view on the environment. Do at least one mock with someone in private equity who will interrupt you.

Where to get question banks and modeling tests

Our honest routing: the free WSO page, WSP’s free paper LBO tutorial and this guide are enough for the fit and technical rounds. Timed Excel modeling tests are where candidates fail, and the WSO course’s nine tests are the closest thing to the real formats we have found; that is the one we would pay for. Our Wall Street Oasis review covers the course prices and the sale mechanics.

Mistakes that end private equity interviews

• Not knowing your own deals. If you cannot state the multiple, the financing and what you would have paid, nothing else you say will matter.
• Doing the paper LBO silently. Talk through every step. The interviewer is grading the structure and can forgive a rounding error; silence gives them nothing to grade.
• Forgetting the returns decomposition. A multiple and an IRR without “where did the return come from” is half an answer.
• Practicing the wrong case format. Ask which of the six formats the firm uses. Preparing a take-home deck for a firm that runs two-hour Excel tests is a wasted week.
• Answering “why private equity” with lifestyle. Hours and carry are the two answers every interviewer has learned to screen out.

Frequently asked questions

What are the most common private equity interview questions?

Why private equity, why our firm, walk me through a deal you worked on, walk me through an LBO, what makes a good LBO candidate, how does a fund make money on a deal, walk me through a paper LBO, and pitch me an LBO target. The twenty above cover the variants.

What is a paper LBO?

A simplified leveraged buyout done in your head or on paper in 10 to 20 minutes without a calculator: set the purchase price and debt, forecast EBITDA and free cash flow, pay down debt, apply an exit multiple, and compute the multiple of money and approximate IRR. The worked example above walks through one.

How technical are private equity interviews?

More technical than banking interviews, because almost every firm includes a modeling test or case study. You need to build an LBO in Excel under time pressure and do a paper LBO from memory, in addition to the fit and deal-experience questions.

What is a good IRR for a private equity deal?

Most buyout funds underwrite to a 20% or higher IRR and a 2.5x or higher multiple of money over roughly five years, with the exact target depending on the fund, the deal’s risk and the leverage used.

When does private equity recruiting happen?

On-cycle recruiting for analysts at large New York banks starts within months of their start date and moves earlier each year, with interviews at the largest funds compressed into a day or two. Off-cycle recruiting, for everyone else, runs over months and weighs deal experience more heavily.

Is the WSO private equity interview course worth it?

If you have modeling tests coming, yes; its nine LBO tests are the closest match to the real formats we have found. For fit and paper-LBO practice alone, the free WSO page, WSP’s tutorial and this guide are enough.
