Investment Banking Interview Questions & Answers (2026)

An LBO model analyzes a PE firm's acquisition of a company using significant leverage. Steps: (1) Set up sources and uses (purchase price, financing structure). (2) Build the debt schedule (term loan, revolver, PIK — interest expense, principal paydown from FCF). (3) Project operating performance (revenue, EBITDA). (4) Calculate FCF to fund debt repayment. (5) At exit, calculate equity proceeds = Enterprise Value - remaining debt. (6) Calculate IRR and MOIC. Target: 20-25% IRR, 2-3x MOIC in 5 years.

Three primary methods: (1) DCF — intrinsic value based on projected free cash flows discounted at WACC plus terminal value. (2) Comparable companies (trading comps) — apply peer group multiples (EV/EBITDA, P/E) to subject company's metrics. (3) Precedent transactions (deal comps) — what have acquirers paid for similar companies? Then triangulate across methods. For M&A: also include a premiums paid analysis and LBO analysis (what can PE afford to pay?).

Merger: two companies combine to form a new entity (rare; typically equals). Acquisition: one company buys another (most common). Types: strategic acquisition (synergies with existing business), financial acquisition (PE buyout for returns), hostile takeover (without target board approval). From an accounting standpoint, most are acquisitions using purchase accounting, where acquired assets and liabilities are revalued to fair market value and goodwill = purchase price - fair value of net assets.

Synergies are value created by combining two companies that either entity couldn't achieve alone. Revenue synergies: cross-selling, new markets, pricing power (harder to achieve, typically discounted). Cost synergies: headcount reduction, facility consolidation, procurement savings (more reliable). Value synergies by estimating annual run-rate impact × tax-affected multiple, then discount for probability of achievement and timing. Buyers pay for synergies through the acquisition premium.

Stages: (1) Preparation (12-18 months): financial audits, legal restructuring, corporate governance, selecting underwriters via beauty contest. (2) Registration: file S-1 with SEC (or F-1 for foreign issuers), SEC review and comment letters. (3) Roadshow (2 weeks): management presents to institutional investors in 2-3 cities per day, building the book. (4) Pricing: night before listing, bankers price based on demand. (5) Trading: first day on exchange. Underwriters support price with stabilization if needed.

EBITDA = Earnings Before Interest, Taxes, Depreciation, and Amortization. It approximates operating cash flow before capex and working capital. Used in investment banking because: it's capital-structure neutral (remove interest), geography/tax neutral (remove taxes), and removes non-cash charges (D&A). EV/EBITDA is the most common transaction multiple. Limitations: EBITDA ≠ cash flow (ignores capex, working capital), and it can be manipulated. Warren Buffett famously calls it a 'meaningless metric.'

Higher rates: increase cost of debt (LBO returns harder to achieve), raise the discount rate in DCFs (lower valuations), reduce PE deal volume, push buyers toward all-cash or all-stock deals, and may cause valuation expectation gaps between buyers and sellers. Lower rates: cheap leverage boosts PE activity, multiple expansion inflates valuations, and strategic acquirers access cheap acquisition financing. Current environment analysis: rising rates since 2022 have compressed deal volumes significantly from 2021 peaks.

Research a recent significant M&A deal before your interview. Structure your answer: (1) Deal overview (acquirer, target, price, structure). (2) Strategic rationale — why did the acquirer buy this? Synergies? Market share? Technology? Geographic expansion? (3) Valuation — is the premium reasonable? What multiple did they pay? (4) Your view — do you think this was a good deal and why? Interviewers are testing whether you read the news and can analyze transactions critically.

IB client relationships are built over years. Early career: be the most prepared person in every meeting, follow up on every commitment same day, bring ideas proactively (not just when hired). Over time: become their trusted advisor by giving them honest advice even when it's not what they want to hear, understanding their business deeply enough to anticipate their needs, and staying in contact between mandates. The best client relationships survive deal outcomes — you maintain them even after a deal falls through.

Investment banks serve as intermediaries between companies that need capital and investors who have capital to deploy. Core functions: (1) Underwriting (IPOs, follow-on equity offerings, debt issuances) — bank takes risk by guaranteeing proceeds to the issuer. (2) M&A advisory — advise buyers and sellers on deal strategy, valuation, and execution. (3) Trading/market making — provide liquidity in securities. (4) Research — produce analysis for institutional investors. The bank's reputation for execution and relationships is its primary competitive advantage.
