Private equity interview practice with a checked paper LBO
For private equity interview practice, calculate the equity return, state the assumptions and explain what would change your view. Start with the original paper LBO below. Soreno's catalog includes finance drills and spoken mocks; match the current material to your invitation and practise spreadsheet tasks separately.
"Soreno quoted the exact moment my answer went vague, then gave me the line I should have said next."
11,900+ applicants accepted at top firms, with over 1.2 million minutes of practice completed.

Purpose-built tools for every stage of your interview prep journey.
Check paper LBO mechanics
The catalog includes Paper LBO Speed Round, with sources-and-uses, quick-return and sensitivity categories. MOIC Calculator and Returns Attribution Analysis cover related calculations. Read the selected exercise and your access limits; catalog entries don't establish a fixed question count or every fund's coverage.
Explain a deal honestly
Use a relevant spoken mock to explain the business, your analysis and your actual contribution. For a public transaction you didn't work on, separate published facts from your interpretation. A target fund entered during setup is context, not evidence of its private questions or scoring rubric.
Challenge the thesis
Identify the assumption that most affects your recommendation and change it. Describe what evidence would support or weaken that assumption. After a voice session, wait for completed feedback and check its comments against the calculation. A practice score isn't an investment recommendation or hiring judgment.
Work a paper LBO, then change the inputs
A fictional buyout with debt paydown. Try the sources and uses and the returns yourself, open the worked solution, then change the exit assumptions and watch the return move.
A fund buys a company with $50 of EBITDA at 8x. It funds the purchase with debt of 5x EBITDA and the rest in equity. The company generates $25 a year after interest, taxes and capital expenditure, and all of it repays debt. After 5 years EBITDA is $70 and the fund sells at 8x. Assume no fees, no cash on the balance sheet and no dividends.
- Build sources and uses and find the equity check.
- Find debt at exit and equity proceeds.
- Find the multiple of money and the annualized return.
- Say where the gain came from.
A fictional deal in $ millions, written by Soreno. Not a real transaction or a fund's interview question.
The follow-up an interviewer asks is what happens to the return if you are wrong. Move the sliders and predict the answer before you read it.
- Exit equity
- $435
- Debt at exit
- $125
- Multiple of money
- 2.90x
- Annualized return
- 23.7%
Split of the gain: $160 from EBITDA growth, $0 from multiple change, $125 from debt paydown. At the base case, exiting at 7x instead of 8x gives about 2.43x and 19.5%.
What this interview tests
- Whether you can set up sources and uses, and size the equity check from the price and the debt.
- Whether you can get from exit enterprise value to equity proceeds, then to a multiple of money and an annualized return.
- Whether you know where the return comes from: earnings growth, multiple change and debt paydown.
- Whether you can say which assumption you trust least and what you would check before believing the return.

The finance drill catalog includes Paper LBO Speed Round, MOIC Calculator and Returns Attribution Analysis. Read each exercise's settings before you start.
- 2Say the logic, not only the number
Spoken mocks let you walk through a deal and answer follow-ups such as what happens to the return if the exit multiple is lower.
- 3A scored report
After a voice session you get a report with quotes from your answer and a plan for the next attempt. Spreadsheet modeling tests are a separate skill and are not reproduced by voice practice.

Original paper LBO: separate enterprise value from equity proceeds
This fictional buyout exercise is for interview rehearsal. It is not a live investment, an employer's test or a claim that the same case is in Soreno's bank. Calculate the equity multiple and annualized return, then explain the risk of the assumed exit price.
- All money figures are in millions of dollars. Entry EBITDA is 20 and the enterprise-value multiple is 10x, so entry enterprise value is 200. New debt of 120 and sponsor equity of 80 fund that amount. Sources equal uses: 120 + 80 = 200.
- At exit exactly five years later, EBITDA is 25 and the exit multiple is 10x. Remaining debt is 80. Assume zero cash at entry and exit, no fees, taxes on the transaction, dilution, interim distributions or additional equity contributions. Ignore other enterprise-to-equity adjustments.
- The debt balance is a supplied assumption, not a forecast you have derived. This short exercise does not model annual interest, operating taxes, capital expenditure or working capital. A full model must show how the business services debt and produces cash.
- Calculate exit enterprise value first, then subtract remaining debt to get equity proceeds. Divide those proceeds by the initial equity investment. With only the initial investment and a single exit payment, the annualized return is (equity multiple raised to 1/5) minus 1.
A worked answer
Entry equity is 200 − 120 = 80. Exit enterprise value is 25 × 10 = 250. With zero cash and 80 of debt, exit equity proceeds are 250 − 80 = 170. The gross equity multiple is 170 ÷ 80 = 2.125x. The five-year annualized return is 2.125^(1/5) − 1, about 16.27%. Those results depend on the stated debt balance and exit valuation, not a guaranteed return.
Enterprise value is not the sponsor's cash proceeds. The sponsor receives the equity remaining after debt under these assumptions. This is a gross deal-level equity result before the omitted fees and other costs; it is not a fund's net investor return. It also doesn't establish that the business can actually repay 40 of debt.
Change one input
Change only the exit multiple to 8x. Keep exit EBITDA at 25, debt at 80 and the five-year holding period. Recalculate the proceeds and return. State what you would investigate before accepting the original 10x assumption.
Exit enterprise value falls to 25 × 8 = 200, leaving equity proceeds of 200 − 80 = 120. The equity multiple is 120 ÷ 80 = 1.5x, and 1.5^(1/5) − 1 is about 8.45%. The original 16.27% falls despite the same EBITDA and debt assumptions. I'd investigate what comparable transactions, business quality and market conditions support the exit multiple, then test a range rather than treat 10x as certain.
Illustrative answer review
An incomplete answer
“We sell for 250 after buying for 200, so the sponsor makes 1.25x and the deal looks safe.”
One repair
“250 is exit enterprise value. After repaying 80 of debt, equity proceeds are 170 on an initial equity investment of 80: 2.125x gross. An 8x exit multiple cuts that to 1.5x. I still need to test cash generation, financing terms and the exit assumptions.”
The repair uses equity proceeds and equity invested consistently. It removes the unsupported safety claim and identifies assumptions that the short exercise hasn't tested. This is our illustrative answer review, not an actual user's feedback or an employer's evaluation.

Choose the next session
- 1
Confirm the actual task
Read the fund's role description and invitation. Confirm whether you need a verbal explanation, written investment case or spreadsheet model. Campus, experienced-hire and regional processes can differ. Don't use a generic on-cycle timeline as a deadline for your own application.
- 2
Check the calculation before speaking
Write the entry financing and exit equity bridge with units. Recompute the return independently and change one input. If the invitation calls for a modeling test, build and check the model in the requested environment; voice practice doesn't reproduce that task.
- 3
Defend one assumption
Explain what would need to be true for the return to hold and which evidence is missing. Choose relevant current Soreno material for the observed gap. In deal discussions, keep confidential details out and state your real role. Wait for processed voice feedback before choosing your next correction.
For a broader schedule and personal-answer preparation, use the communication practice plan. Keep the next app session focused on the gap you observed.
