Private equity interviews shift the question from 'what is it worth' to 'how do we make money owning it.' That reframes everything: cash-flow stability, the entry multiple, the debt that can be raised, and the realistic path to a higher exit.
The questions below come from our interview question bank, grouped by difficulty. Each shows the interviewer's phrasing plus a compressed model answer. The core test is whether you can reason like an owner — name the value-creation levers and the return they drive, not just the mechanics.
Why PE questions test ownership thinking
PE rewards a returns mindset: the three levers are deleveraging, EBITDA growth and multiple expansion. A strong answer ties a deal back to which lever does the work.
It also tests deal judgment: what makes a clean LBO candidate (stable cash flow, low capex, defensible position) versus a business that can't carry leverage. Sponsors screen hard, and so should your answer.
Warm-up questions
Q: What are the main exit routes for a PE fund?
A (summary): Strategic sale, sponsor sale, IPO, recapitalization, or partial sale. The best route depends on market, scale, and thesis. Key points: Strategic sale; Sponsor sale; IPO.
Q: What does a PE investment committee memo need to prove?
A (summary): It needs to prove thesis, downside, returns, risks, value creation plan, financing capacity, and management quality. Key points: Thesis; Downside; Returns.
Q: What are the main diligence workstreams in PE?
A (summary): Commercial, financial, legal, tax, operational, technology, ESG when relevant, and market thesis confirmation. Key points: Commercial; Financial; Legal/tax.
Q: What are the value creation levers in Private Equity?
A (summary): Revenue growth, margin expansion, deleveraging, working capital improvement, add-ons, and possible exit multiple expansion. Key points: Revenue growth; Margin expansion; Deleveraging.
Core questions
Q: What is the difference between a platform investment and an add-on acquisition?
A (summary): A platform is the initial investment that anchors the thesis. An add-on is a smaller acquisition integrated into the platform to gain scale, synergies, or geography. Key points: Platform anchors thesis; Add-on builds scale; Integration matters.
Q: What is multiple arbitrage in a buy-and-build strategy?
A (summary): It is buying smaller add-ons at lower multiples and integrating them into a platform valued at a higher multiple, creating value beyond operating synergy. Key points: Lower add-on multiples; Platform multiple; Integration value.
Q: Why is Quality of Earnings central in PE?
A (summary): Because it validates recurring EBITDA, adjustments, seasonality, and cash risk, avoiding paying a full multiple for unsustainable earnings. Key points: Recurring EBITDA; Adjustments; Cash conversion.
Q: What trade-off exists when maximizing leverage in a buyout?
A (summary): More debt can increase base-case IRR, but reduces flexibility, increases covenant/default risk, and limits investment in the operating plan. Key points: Higher base-case IRR; Lower flexibility; Default risk.
Hard questions
Q: Explain the basic mechanics of an LBO and the main drivers of returns.
A (summary): PE acquires a company using 60-80% debt and 20-40% equity. Steps: 1) Find target with stable cash flow and assets to leverage.
Common mistakes
- Confusing IRR and MOIC MOIC is total multiple of money; IRR is time-weighted. A 3x over seven years and a 3x over three years are very different — name the horizon.
- Treating any company as an LBO target Cyclical, capex-heavy or fast-burning businesses struggle under leverage. Screen on cash-flow stability before you model returns.
- Ignoring multiple expansion risk Assuming exit > entry multiple inflates returns. Strong answers earn the return through operations, not optimistic exit assumptions.
How to structure your answer
Open with the framework in one line, state your assumption, give the number or direction, then name the trade-off. Interviewers reward a thesis with a caveat over a confident monologue.
