Deal-modeling tests and technical prep

#Why PE technical screening looks different from IB's

Where an IB interview tests whether you understand how financial statements connect (Module 03), a PE interview tests something more specific: can you actually build, or at minimum reason cleanly through, the mechanics of a leveraged buyout — a deal structure where a fund buys a company using a mix of its own equity and significant borrowed debt, then aims to grow the company's cash flow, pay down that debt, and sell at a profit within roughly three to seven years. [Established] for the LBO structure itself, which is standard private-equity mechanics; [Directional] for the specific screening emphasis, synthesized across multiple PE-recruiting practitioner guides rather than any one firm's own published rubric.

#Stage one: the paper LBO

A paper LBO is exactly what it sounds like: an interviewer gives you a short verbal or written scenario — a company's revenue, EBITDA margin, growth rate, capital-expenditure assumption, tax rate, purchase multiple, amount of debt used, and an assumed exit multiple — and asks you to work out the approximate return (IRR, the annualized rate of return, and MOIC, the multiple of invested capital) using mental math and a pen, no spreadsheet or calculator. [Directional] It typically appears early in the process, often in a first round or even administered by a headhunter as a pre-screen, specifically because it's fast to run and effectively filters out candidates who don't genuinely understand LBO mechanics before a firm invests interviewer time in a longer round. [Directional] Reported time allowances range from roughly five to thirty minutes depending on the firm and the scenario's complexity. [Directional]

The mechanical shape of a paper LBO, stripped to its core logic: figure out the entry equity investment (purchase price minus debt used), project the company's cash flow forward using the given growth and margin assumptions, use that cash flow to pay down the debt over the holding period, calculate the exit equity value (exit EBITDA times exit multiple, minus remaining debt), and divide exit equity by entry equity for MOIC — then translate MOIC and the holding period into an approximate IRR using compounding shortcuts (roughly: a 2x MOIC over 5 years is approximately a 15% IRR; a 3x MOIC over 5 years is approximately a 25% IRR) rather than a precise formula. [Established] for the underlying mechanics, which follow directly from the definitions of IRR and MOIC; [Directional] for the specific mental-math shortcuts and rounding conventions practitioners recommend memorizing.

#Stage two: the timed Excel modeling test

Later in the process — after the paper LBO has screened out candidates who don't understand the mechanics at all — most PE firms run a longer, computer-based modeling test: build a working LBO model in Excel from a set of assumptions, under a hard time limit, commonly reported in the one-to-three-hour range, sometimes extended into a take-home format for a subset of firms. [Directional] This tests something the paper LBO cannot: whether a candidate can actually build a clean, correctly-linked, auditable model under real time pressure, not just reason through the concept verbally. [Directional]

#Stage three: the case study and deal walkthrough

Later rounds, often the final round with more senior investment professionals, commonly add two further components: a case study — evaluate a real or disguised investment opportunity and present a view on whether the firm should pursue it, sometimes with a management-team role-play built in — and a deal walkthrough, where the candidate is asked to present a real deal they worked on as a banking analyst in detail: what the company did, why the client pursued the transaction, what the biggest risks were, and what they personally contributed to the analysis. [Directional] The deal walkthrough in particular functions as a check on the "why banking" narrative from Module 03: it's difficult to fake genuine, detailed command of a deal you didn't actually understand while working on it, which is part of why PE firms use it as a late-stage filter rather than an early one.

#What this sequence is actually testing, end to end

Read together, the three stages test three separable things in ascending order of difficulty and interviewer time investment: conceptual fluency with LBO mechanics (paper LBO), the ability to execute that fluency correctly under pressure in the actual tool the job requires (modeling test), and genuine, detailed command of real deal experience combined with independent investment judgment (case study and deal walkthrough). [Directional] A candidate who has memorized paper-LBO shortcuts without genuinely understanding why they work tends to fail at the modeling-test stage, where surface memorization doesn't survive contact with a real, messier set of assumptions — which is the same underlying failure mode Module 03's sibling course, MBB, documents for a memorized consulting framework breaking down against a case that doesn't fit it.

The next module covers what the job actually pays once you're in it, and — more importantly — the fund-economics structure (management fee plus carried interest) that explains why PE firms are built to want the outcome this interview process is screening for.
