The Investment Banking Interview Guide

What the job actually is, how deals work, and the language of the Street.

• What is investment banking?What investment bankers actually do all day, how a deal team is structured from analyst to MD, and why the analyst is the engine that makes the whole thing move.
• Buy-side vs. sell-sideSell-side banks advise companies and sell securities; buy-side firms invest capital and take the risk. Where an analyst sits, what each does day to day, and why the two meanings of these words trip up beginners.
• Capital markets: ECM and DCMHow companies raise money by selling stock (ECM) or issuing bonds (DCM), what underwriting is and why the bank puts its own capital at risk, and how a company decides between debt and equity.
• How a deal actually gets doneA live deal isn't one big event. It's months of staged work, and the analyst is the engine that carries each stage. Here's the lifecycle from pitch to close, and where the hours spike.
• Why investment banking?The easiest question to fail. Why prestige and money answers get you dinged, why the real reason is the education, and how to prove you fit what banks look for.
• What banks are really looking forBeing smart is table stakes. What actually gets you hired is proving you get it, you'll grind when it counts, and your work is accurate under pressure. How to show it.
• The IPO processHow a private company goes public: hiring underwriters, filing the S-1, running the roadshow, building the book, pricing the night before, and why the stock so often pops on day one.

The three statements, how they link, and the questions every interviewer asks.

• The income statement, line by lineRevenue down to net income, one layer of cost at a time. What each subtotal means, why interest and taxes sit below operating income, and the margins interviewers actually ask about.
• The balance sheet, both sidesThe balance sheet is a point-in-time snapshot of what a company owns and how it paid for it. Assets always equal liabilities plus equity, and knowing why is your check on every accounting answer.
• The cash flow statement, section by sectionThe cash flow statement reconciles accrual net income back to real cash across three sections (operating, investing, financing). This is how it's built and why profit is not the same as cash.
• Walk me through the three statementsWhat each of the three statements actually is, the subsections inside them, how they link, and the $10 depreciation walk interviewers use to test whether you really get it.
• Depreciation and amortizationDepreciation and amortization spread the cost of long-lived assets over their useful life. Both are non-cash, both get added back on the cash flow statement, and the only real cash they move is the tax they save.
• Working capital, and why it eats cashWorking capital is the cash tied up in running the business day to day. When it grows, it drains cash and free cash flow, which is why fast-growing companies can be starved for cash even while profits look great.
• EBITDA and the bridge to free cash flowWhat EBITDA actually is, why bankers lean on it, and the exact bridge from EBITDA to unlevered free cash flow. EBITDA is not cash. Capex, taxes, and working capital are the gap.
• Deferred revenueCash collected before you deliver the product is a liability, not revenue. Here's how deferred revenue works, why it never touches the income statement until earned, and why investors love the businesses that carry a lot of it.
• Deferred taxes: DTAs and DTLsDeferred taxes exist because a company keeps two sets of books, one for shareholders and one for the IRS. DTLs mean you will pay more cash tax later; DTAs mean you will pay less. Here is the timing logic and how each unwinds.
• Goodwill and purchase accountingWhen a buyer pays more than the fair value of the identifiable net assets it acquires, the excess lands on the balance sheet as goodwill. Here is how purchase accounting actually works, why asset write-ups create a deferred tax liability, and why goodwill is tested for impairment, not amortized.
• Stock-based compensationSBC is a real expense that reduces net income but burns no cash, so it gets added back on the cash flow statement. The catch is the dilution.
• Diluted shares and the treasury stock methodA company's share count is not one number. Basic vs diluted shares, where dilution comes from, and the treasury stock method worked step by step with clean numbers, plus why diluted shares are the count that drives equity value and EPS.
• Dividends and buybacksThe two ways a company hands cash back to shareholders. Dividends pay a steady amount per share; buybacks shrink the share count and lift EPS. Why neither creates value on its own, worked with clean numbers.
• Operating leverageOperating leverage is how much of a company's cost base is fixed. High fixed costs mean a small revenue move produces a large profit move, up or down. Contribution margin, flow-through, and break-even explained.

Enterprise vs. equity value, multiples, and how to triangulate what a company is worth.

• How bankers value a companyThere is no single "right" value for a company. Bankers run three or four methods, each answering a different question, and present a range. Here's the toolkit, why the methods disagree, and how the football field ties them together.
• Enterprise value vs. equity valueEnterprise value is what the operating business is worth; equity value is what the shareholders own. The bridge between them, and why cash is subtracted rather than added, is the single most-tested relationship in valuation.
• The multiples that matterEV multiples pair with pre-interest metrics, equity multiples pair with post-interest ones. Get the pairing right and you understand valuation.
• Trading comparablesComparable companies analysis values a business off what the market is paying for similar public companies right now. How to pick the set, which multiples to use, and why EV/EBITDA is the workhorse.
• Precedent transactionsPrecedent transactions value a company off what acquirers actually paid for similar businesses in past M&A deals. The control premium, why they run high, and how they differ from trading comps.

Free cash flow, WACC, terminal value — building a discounted cash flow from scratch.

• The DCF, explainedA discounted cash flow values a company by its own future cash flows. The unlevered FCF build, WACC, terminal value, and the sequence and bridge mistakes that trip people up.
• Time value of moneyA dollar today beats a dollar next year, and that one idea is the engine under every valuation. Present value, discount factors, perpetuities, and why rising rates push valuations down, worked with clean numbers.
• Unlevered free cash flowUnlevered free cash flow is the cash a business generates before any debt payments, so it belongs to every capital provider. The EBIT-based build, why it pairs with WACC, and a clean worked example.
• CAPM and the cost of equityThe cost of equity is the return shareholders demand for the risk they take. CAPM builds it from three inputs, risk-free rate plus beta times the equity risk premium, and it feeds straight into WACC and the DCF.
• Levered vs. unlevered betaA company's observed beta is contaminated by its debt. To value a business you strip debt out (unlever) and re-apply your target's own debt (relever). The two formulas, why it matters, and the errors interviewers fish for.
• The market risk premiumThe extra return investors demand for holding stocks over risk-free bonds. It's the price of risk in the whole market, the same number for every company you value that day, scaled by beta. Where it comes from, why it runs 5-7%, and how not to mangle it.
• WACC, explainedWACC is the blended return debt and equity holders demand, and it's the discount rate for unlevered cash flows. The formula, why you use market weights, and the after-tax cost of debt.
• Terminal valueTerminal value captures everything past your forecast window and usually drives most of a DCF. The two methods (Gordon growth and exit multiple), why you need WACC first, and why you still discount it back.
• DCF conventions and the errors that sink youThe DCF logic is easy. The conventions and the sequence are where candidates lose the offer, so here are the mid-year convention, stub periods, sensitivity tables, and the mistakes that read as sloppy.
• The yield curve and interest ratesA bond's yield is the return you earn holding it to maturity, and plotting yields against maturity gives the yield curve. Here is how it slopes, what inverts it, and why every deal reads it.

Accretion/dilution, synergies, and the mechanics of buying a company.

• How M&A deals actually workM&A is not one negotiation. It's a staged process with a teaser, a CIM, rounds of bids, and exclusivity, and understanding who can pay more (strategics vs. sponsors) is the thing that separates you.
• Cash vs. stock: how a deal is paid forHow an acquirer pays (cash, debt, or its own shares) drives whether a deal is accretive or dilutive. The cheap-debt intuition, the buyer-vs-target P/E rule for stock deals, and the signal a stock deal sends.
• Synergies: the number that justifies the premiumSynergies are the extra value two companies create together that they couldn't apart. Cost synergies are credible and near-term; revenue synergies are softer. Here's how they justify a control premium, and how deals destroy value by paying the whole thing away.
• Accretion / dilutionAccretion/dilution asks whether a deal raises or lowers the acquirer's earnings per share. The P/E rule of thumb for stock deals, why cash deals usually look accretive, and what the test does and doesn't tell you.
• Building a merger modelA merger model is a sequence, not a spreadsheet. Sources and uses, purchase accounting and goodwill, combine the income statements, then land on pro-forma EPS and accretion/dilution.
• Strategic buyers versus financial buyersWhen a company is for sale, the bidders split into two camps: strategics who fold the target into their own business, and financial sponsors who buy it as a standalone investment. Who they are shapes who pays more and who usually wins.
• Asset deals versus stock dealsThe two legal ways to buy a company. A stock deal buys the whole entity and every liability with it. An asset deal buys chosen assets and hands the buyer a tax step-up. Plus the 338(h)(10) election that gets you both.
• What a sell-side M&A process looks likeA stage-by-stage walk through a sell-side M&A deal, from pitch to close, told from the deal team's seat. What each document does, why the whole game is competitive tension, and what the analyst actually owns day to day.
• Shareholder activism and how bankers help clientsWhat shareholder activists want, the language of a campaign from 13D filings to proxy fights, and how bankers defend a company: vulnerability reviews, stock surveillance, and the fight-or-settle decision.

Leverage, returns drivers, and why private equity loves debt.

• The LBO and the paper LBOA leveraged buyout buys a company mostly with borrowed money, then uses the company's own cash flow to pay it down. Sources and uses, IRR and MOIC, and how to run a paper LBO in your head.
• What makes a good LBO candidateThe best LBO targets are boring on purpose. Stable, predictable cash flow that services debt, low capex, a defensible market position, hard assets for collateral, and a clear way out. Why cash-flow stability beats a growth story.
• Sources and usesThe Sources and Uses table is where every LBO starts. Uses is everything you have to pay for; Sources is where the money comes from. The sponsor's equity check is the plug that makes them tie.
• Debt tranches and seniorityHow the capital stack is layered in an LBO, why cost rises as you go down, and who gets paid first when a deal goes bad.
• IRR and MOICThe two numbers a private equity sponsor cares about. MOIC tells you how many times you multiplied your money; IRR tells you how fast. Here's how they connect and how to reason about them in your head.
• What drives LBO returnsAn LBO makes money three ways: paying down debt, growing EBITDA, and selling at a higher multiple than you paid. Here is how leverage amplifies the equity return, and how to walk a clean entry-to-exit bridge to a MOIC.
• Credit ratings and leverage ratiosHow agencies grade a borrower from AAA down to default, where investment grade ends and junk begins, and how leverage and coverage ratios drive both the rating and the cost of debt.
• Capital structureCapital structure is the mix of debt and equity a company uses to fund itself. Debt is cheaper but comes with fixed payments and bankruptcy risk, equity is expensive but forgiving, and the balance drives both WACC and LBO returns.
• Restructuring basicsWhat happens when a company cannot pay its debts. Out-of-court deals versus Chapter 11, the absolute priority waterfall, recovery rates, and why the fulcrum security ends up owning the reorganized business.

Best practices, circularity, and structuring a model an MD can actually read.

• Financial modeling best practicesThe habits that make a model trustworthy: blue inputs and black formulas, one assumptions area, one-directional flow, no buried hardcodes, no plugs, and checks that prove the balance sheet balances.
• Building a three-statement modelHow the income statement, balance sheet, and cash flow statement wire together in an actual model, how the debt schedule feeds interest, and the one-statement-at-a-time way to debug when the balance sheet won't balance.
• The debt schedule and circular referencesA debt schedule tracks how much debt a company owes each year, and it creates a famous circular reference. Here is why the loop exists and how to control it.

Mental math, logic puzzles, and the curveballs that test how you think on your feet.

• Brainteasers and market sizingBrainteasers are a small slice of IB interviews, usually filler. The one that actually shows up is market sizing, and it's graded on your structure and stated assumptions, not the exact number.
• Mental math for the interviewNo calculator in the room, so build reflexes. The rule of 72, quick percentages, growth math, and estimating IRR from MOIC, all with clean round numbers.
