Used by finance candidates preparing for PE interviews at buyout and growth equity firms across the UK

Last updated: March 2026

Private equity interviews are among the most demanding in finance. They test financial modelling ability, investment judgment, deal knowledge, and cultural fit with a small partnership — all simultaneously. The process varies by firm and strategy (buyout, growth equity, venture, infrastructure), but the preparation framework is consistent: master the technical foundations, develop genuine investment views, and practise your deal experience until you can discuss it fluently from any angle. This guide covers all four question types and the preparation approach that gets candidates offers.

The 4 PE Interview Question Types

Technical finance

LBO mechanics, valuation, accounting, return attribution. Tests whether you have the financial toolkit to evaluate and structure investments.

"Walk me through an LBO model." / "What happens to equity value if EBITDA grows 20%?"

Deal experience

Detailed discussion of transactions you've worked on — the thesis, the structure, the due diligence, and what happened. Tests real-world application of financial skills.

"Walk me through the most interesting deal you've worked on."

Investment judgment

A live investment or sector discussion — what do you think of this company? Would you invest? What's the thesis? Tests commercial intuition and analytical thinking.

"What do you think about the UK care home sector as a PE investment right now?"

Fit and motivation

Why PE, why this firm, what deals interest you, how do you think about your career. Tests genuine motivation, sector knowledge, and cultural fit with a small team.

"Why do you want to move from banking to PE rather than staying in a bank?"

Key Technical Areas to Master

Technical questions in PE interviews are more applied than in banking. You're expected to connect financial mechanics to investment decisions — not just demonstrate that you can build a model.

01

LBO Mechanics and Return Drivers

Core technical foundation

PE returns come from three sources — multiple expansion, EBITDA growth, and debt paydown. Be able to attribute returns across all three and discuss which lever dominates in a given scenario.

  • Entry: Purchase price = Entry EV/EBITDA × EBITDA; sources = debt + equity
  • Holding period: EBITDA grows, FCF pays down debt, equity value builds
  • Exit: Exit EV = Exit EV/EBITDA × Exit EBITDA; equity proceeds = Exit EV − remaining debt
  • Returns: MoM = Exit equity / Entry equity; IRR derived from time-weighted MoM
  • Sensitivity: Know how changes in entry multiple, exit multiple, leverage, and growth affect IRR
02

Paper LBO Framework

15–30 minute mental exercise

A paper LBO tests whether you can quickly estimate returns from a set of assumptions without a spreadsheet. Speed and accuracy both matter — practice is the only way to improve.

  • Step 1: Calculate entry equity cheque (Enterprise Value − debt at entry)
  • Step 2: Project EBITDA at exit using the growth assumption
  • Step 3: Calculate exit EV using the exit multiple assumption
  • Step 4: Estimate debt remaining at exit (entry debt − FCF × years)
  • Step 5: Exit equity = Exit EV − remaining debt
  • Step 6: MoM = Exit equity / Entry equity; estimate IRR from MoM and holding period
  • IRR rules of thumb: 2× in 3 years ≈ 26%; 2× in 5 years ≈ 15%; 3× in 5 years ≈ 25%
03

Investment Thesis Framework

Investment judgment questions

When asked to evaluate a company or sector, structure your view around the quality of the business, the attractiveness of the opportunity, and the risks to the thesis.

  • Business quality: sustainable competitive advantage, pricing power, cash generation
  • Market dynamics: size, growth rate, cyclicality, regulatory environment
  • Financial profile: EBITDA margins, FCF conversion, leverage capacity, working capital
  • PE fit: can returns be generated through leverage + operational improvement + exit?
  • Key risks: what would make you pass? What could go wrong post-close?
  • Valuation: at what entry multiple does this work? What's the exit path?
04

Deal Walk Structure

"Walk me through a deal you've worked on"

Structure your deal discussion to demonstrate investment judgment — not just execution. Interviewers want to know you understand why the deal was attractive, not just that you built the model.

  • The company: sector, business model, scale, market position
  • The investment thesis: why was this an attractive PE opportunity?
  • The deal: entry price, EV/EBITDA, leverage, equity cheque
  • Your role: specifically what you worked on and what decisions you influenced
  • Key diligence findings: what made you more or less confident in the thesis?
  • What you'd do differently: shows genuine reflection and learning

8 Tips for Acing Your PE Interview

1

Master the paper LBO before anything else

The paper LBO is the single most common filter in PE interviews. Candidates who can't do one quickly and accurately under pressure are screened out regardless of how strong the rest of their preparation is. Practise at least one paper LBO per day in the two weeks before your interview — with different entry prices, leverage assumptions, and holding periods. The IRR rules of thumb (2× in 5 years ≈ 15%, 3× in 5 years ≈ 25%) should be completely internalised.

2

Know your deals inside out from every angle

For every deal you mention, be able to discuss it from any angle — the accounting, the debt structure, the exit multiple, the key risks, the due diligence process, and your specific contribution. PE interviewers probe deal experience deeply and inconsistency or superficial knowledge is immediately obvious. If you've worked on a deal that has since been announced or completed, know what actually happened and be prepared to compare it to the original thesis.

3

Develop genuine investment views before the interview

PE investors need to have and defend opinions. Before your interview, prepare an investment view on two or three sectors or companies — something you'd want to buy, something you'd pass on, and why. These don't need to be perfect; they need to be thoughtful and specific. Being able to say "I've been following the UK veterinary sector and here's what I find interesting" signals the kind of curiosity and initiative that PE firms are looking for in a junior investor.

4

Research each firm's strategy, portfolio, and recent activity

Generic answers in PE interviews are immediately detectable. Before each interview, know the firm's fund size and strategy (buyout, growth, sector-focused), their current and recent portfolio companies, any deals they've done in sectors you've worked on, and how their approach differs from their peers. Referencing a specific portfolio company and asking a thoughtful question about it signals genuine interest and the kind of research-driven mindset that PE firms value.

5

Be able to articulate why PE specifically

"Why PE?" is one of the most important questions in the interview and one of the most commonly answered poorly. "More interesting than banking" is not sufficient. Develop a specific, honest answer about what attracts you to the investor seat — the ownership mentality, the longer holding periods, the operational involvement, the fund economics. Connect it to specific things you've observed in deals you've worked on that made you want to be on the buy-side rather than the advisory side.

6

Practise discussing valuation across multiple methodologies

PE interviewers test whether you can triangulate value — not just run one methodology. Be comfortable discussing DCF, comparable companies, precedent transactions, and LBO valuation simultaneously, and be able to explain why they might diverge for a given company. For a high-growth business, why might the LBO value be lower than the DCF? For a distressed company, why might precedent transactions overstate value? These are the questions that separate strong candidates from very strong ones.

7

Know the key accounting concepts cold

PE interviewers frequently test accounting knowledge because it underpins deal analysis. Know how the three financial statements link, how to calculate free cash flow from EBITDA, what normalisation adjustments are and why they matter, how working capital affects cash generation, and the key differences between GAAP and reported EBITDA. Candidates who are fuzzy on accounting basics struggle when deals involve complex structures or earn-outs.

8

Practise answering questions concisely and with conviction

PE interviews reward directness. Interviewers are senior professionals with limited patience for answers that hedge, qualify, and avoid a point. When asked a technical question, answer it directly then explain your reasoning. When asked for an investment view, give one — then defend it when pushed back. The ability to communicate clearly and hold a position under pressure is itself a signal of the kind of junior investor you'd be. Practise giving structured answers out loud against a timer.

Frequently Asked Questions

What types of questions are asked in a private equity interview?

PE interviews typically include four question types: technical finance (LBO modelling, valuation, accounting), deal experience (walk me through a deal you've worked on), investment judgment (would you invest in this business?), and fit and motivation (why PE, why this firm?). The balance varies by firm — larger buyout funds tend to be more technically rigorous; growth equity firms often weight investment judgment more heavily.

What is a paper LBO and how do I prepare for one?

A paper LBO is a back-of-the-envelope leveraged buyout model done on paper in 15 to 30 minutes. You'll be given an entry price, debt structure, and exit assumption, and asked to estimate the IRR and money-on-money return. To prepare: memorise the LBO mechanics, practise doing them quickly with round numbers, and internalise the IRR rules of thumb (2× in 5 years ≈ 15%, 3× in 5 years ≈ 25%). Candidates fail paper LBOs through lack of practice, not lack of understanding.

How do I answer "walk me through a deal" in a PE interview?

Structure your deal walk as: the company and sector context, the investment thesis, the deal structure, your specific role and contribution, what happened post-close if applicable, and what you would have done differently. The interviewer is assessing whether you understand deals at a commercial level — not just the mechanics — and whether you can speak with conviction about the investment rationale.

What financial concepts should I know for a PE interview?

At a minimum: LBO mechanics and return drivers, valuation methodologies (DCF, comparable companies, precedent transactions), key accounting concepts (working capital, EBITDA adjustments, free cash flow), and debt structures. For more senior roles, add portfolio company KPIs, value creation frameworks, and sector-specific dynamics.

How is a PE interview different from investment banking?

PE interviews are more investment-focused than execution-focused. In banking you demonstrate you can build models and execute transactions. In PE you need to demonstrate investment judgment — you can identify attractive opportunities, assess risk, and make recommendations. PE interviews also place much greater weight on commercial intuition, genuine investment views, and cultural fit with a small partnership.
