Top 50 Investment Banking Interview Questions & Answers

Quick answer: The most common investment banking interview questions test seven areas: financial statements, valuation and enterprise value, DCF analysis, M&A, LBOs, IPOs, and deal processes. Interviewers expect a structured answer of about 60 seconds that states the conclusion first, then the reasoning — the format every answer below follows.

Most candidates don’t lose an investment banking offer on an obscure question. They lose it on the fundamentals: a walk-through that doesn’t balance, a DCF explained in three rambling minutes, an accretion/dilution answer with the logic backwards.

This guide covers the 50 questions that come up again and again, from first-round screens to superdays. Every answer is written the way you should deliver it in the room — the answer first, then the reasoning, in about 60 seconds.

It’s part of our guide on how to become an investment banker in India, which covers the routes in, qualifications and salary. This article covers the stage that decides the offer: the interview.

How to use this guide. Work through the sections in order: financial statements underpin valuation, and valuation underpins DCF, M&A and LBO analysis. Say each answer out loud until you can deliver it without notes. Walk-throughs assume a 25% tax rate — in an interview, state your tax assumption out loud; 25% or 40% are both accepted if you stay consistent.

1. Financial statement interview questions

Every valuation and model rests on the three statements, so interviewers use accounting to test whether you think in linkages. Master the walk-through pattern once and you can answer any variation.

1Walk me through the three financial statements.

The income statement shows revenue, expenses and net income over a period. The balance sheet is a snapshot of assets, liabilities and shareholders’ equity at a point in time, where assets = liabilities + equity. The cash flow statement starts with net income, adjusts for non-cash items and working capital, then adds investing and financing flows to show the change in cash.

2How are the three financial statements linked?

• Net income flows to the top of the cash flow statement and into retained earnings on the balance sheet.
• Non-cash charges (D&A, stock-based compensation, impairments) are added back on the cash flow statement and reduce the related balance sheet asset.
• Changes in working capital accounts on the balance sheet appear in cash from operations.
• Capex increases PP&E; debt and equity issuance or repayment change the matching balance sheet lines.
• The net change in cash on the cash flow statement becomes the cash balance on the balance sheet.

3If you could use only one financial statement to evaluate a company, which would you choose?

The cash flow statement — it shows the actual cash a business generates, which is harder to manipulate than accounting earnings. If allowed two, choose the income statement and the balance sheet, because you can rebuild the cash flow statement from them.

4Depreciation increases by $10. Walk me through the three statements.

This is the template answer — learn its rhythm.

1. Income statement: operating income falls by $10. At 25% tax, net income falls by $7.50.
2. Cash flow statement: net income is down $7.50, but depreciation is added back, +$10. Cash rises by $2.50.
3. Balance sheet: cash is up $2.50 and PP&E is down $10, so assets fall $7.50. Retained earnings fall $7.50. Both sides are down $7.50, so it balances.

The insight: depreciation is non-cash, so its only cash effect is the $2.50 tax saving. The same pattern answers most variations:

5A company buys $100 of PP&E with debt. What happens on day one, and after a year?

Day one: nothing hits the income statement. On the cash flow statement, capex is −$100 and debt issued is +$100, so cash is unchanged. On the balance sheet, PP&E and debt both rise by $100.

After a year (10-year life, 10% interest): pre-tax income falls $20 ($10 depreciation + $10 interest), so net income falls $15. Adding back $10 of depreciation leaves cash down $5. On the balance sheet, cash −$5 and PP&E −$10 cut assets by $15; retained earnings fall $15; debt stays at $100.

6Why can a profitable company go bankrupt?

Profit is not cash. A fast-growing company can tie up cash in receivables and inventory, or face a large debt maturity it cannot refinance. Bankruptcy is a liquidity event: failing to pay obligations when due.

7What is working capital, and why does an increase reduce cash?

Operating working capital = current operating assets (receivables, inventory) − current operating liabilities (payables, accrued expenses, deferred revenue). When it rises, the business has invested cash in operations — customers owe more, or more inventory sits on the shelf — so cash from operations falls.

8What is EBITDA, and why do bankers use it?

Earnings before interest, taxes, depreciation and amortization — a proxy for operating cash flow that is independent of capital structure, tax jurisdiction and depreciation policy. That makes it comparable across companies. Its flaws: it ignores capex, working capital and taxes, all of which are real cash costs.

9What is goodwill, and when is it impaired?

Goodwill is the excess of the purchase price over the fair value of an acquired company’s net identifiable assets. Example: pay $500 for a target with $200 of book equity and $100 of asset write-ups → goodwill = $500 − ($200 + $100) = $200, before deferred tax adjustments.

Goodwill is not amortized under US GAAP or IFRS; it is tested for impairment at least annually. It is written down when the carrying value of the business unit exceeds its fair value — usually a sign the acquirer overpaid.

2. Valuation and enterprise value interview questions

Equity value is what shareholders own; enterprise value is what the core business is worth to all capital providers. Get that distinction right and the valuation methods — trading comps, precedent transactions, DCF — follow naturally.

10What is the difference between equity value and enterprise value?

Enterprise value represents the operating business, available to debt holders, preferred holders and equity holders together. Equity value is the residual claim of common shareholders only.

11Why do you subtract cash and add noncontrolling interest?

Cash is a non-operating asset: an acquirer effectively gets it back at closing, so subtracting it isolates the operating business. Noncontrolling interest is added because a company that owns 70% of a subsidiary consolidates 100% of its EBITDA — EV must include the 30% it does not own to stay consistent. Preferred stock is added because it is a claim senior to common equity.

12How do you calculate diluted shares using the treasury stock method?

Only in-the-money options count. Assume they are exercised, then assume the company uses the proceeds to buy back shares at the current price.

Example: 100 basic shares at $50, plus 10 options with a $20 strike. Proceeds = 10 × $20 = $200, which buys back $200 / $50 = 4 shares. Net new shares = 6, so diluted shares = 106. Convertible bonds use the if-converted method: if in the money, add the conversion shares and remove the debt.

13Which multiples use enterprise value, and which use equity value?

Match the numerator to the capital providers the denominator serves.

EV / Net income is wrong: the numerator includes debt holders, but net income is after they have been paid.

14How do these transactions affect equity value and enterprise value?

These hold in theory, at the moment of the transaction; in practice, markets may re-price.

15What are the main valuation methodologies?

Bankers show the ranges side by side on a football field — a horizontal bar chart with every method on one scale and the offer or share price drawn as a line.

16Which methodology usually gives the highest value?

Precedent transactions typically come out highest, because they include a control premium and expected synergies. DCF is the most variable — it can land anywhere, depending on assumptions. Trading comps reflect minority stakes, so they tend to sit lower. Always add “it depends on the situation” and explain why.

17Walk me through a trading comps analysis.

1. Select a peer set: same industry and business model, then filter by size, geography, growth and margins. Five to ten good peers beat twenty loose ones.
2. Gather financials, share prices, share counts and debt from filings and consensus estimates.
3. Calculate equity value, enterprise value and key multiples (EV/Revenue, EV/EBITDA, P/E) on LTM and forward figures.
4. Look at the range, median and quartiles; exclude clear outliers with a stated reason. Anchor on the median, which resists outliers.
5. Apply the chosen multiple range to the target’s metrics to get an implied valuation range.

18How are precedent transactions different from trading comps?

Precedents use prices paid in completed deals, so they include a control premium — often in the range of 20–40% over the unaffected share price for public targets. Screen by industry, size, date and deal type. Weight recent deals more heavily, because valuation levels shift with interest rates and credit conditions.

3. DCF interview questions

A DCF values a business as the present value of the cash it will generate, discounted at the return its capital providers require. “Walk me through a DCF” is the single most-asked technical question — you must deliver it in 60 seconds, flawlessly.

19Walk me through a DCF.

“First, project the company’s unlevered free cash flow for five to ten years, driven by revenue growth, margins, capex and working capital. Second, calculate a terminal value at the end of the projection, using either the perpetuity growth method or an exit multiple. Third, discount the cash flows and terminal value back to today at the WACC. The sum is enterprise value. Subtract net debt and other claims to get equity value, and divide by diluted shares for an implied share price.”

20How do you calculate unlevered free cash flow, and why use it?

Start from EBIT, not net income, because unlevered FCF is before interest. It is the cash available to all capital providers, so it pairs with WACC and produces enterprise value, independent of the current capital structure. Many banks also subtract stock-based compensation, treating it as a real cost.

21How do you calculate WACC?

Use market values, ideally at a target capital structure. The cost of debt is after-tax because interest is tax-deductible. The cost of equity comes from CAPM.

22How do you calculate the cost of equity?

The risk-free rate is a long-term government bond yield in the currency of the cash flows. Beta measures sensitivity to the market, and the equity risk premium is the extra return investors demand over the risk-free rate. For a private company, take peers’ betas, unlever them, take the median, then relever at the target’s capital structure:

23Why is the cost of equity higher than the cost of debt — and what happens to WACC as debt rises?

Equity holders are paid last in bankruptcy and have no contractual return, so they bear more risk; interest is also tax-deductible. So adding debt first lowers WACC, as cheaper debt replaces equity. Past a point, distress risk pushes up both the cost of debt and the cost of equity, and WACC rises again — a U-shape with the optimal capital structure at the bottom.

24What are the two ways to calculate terminal value?

The perpetuity growth (Gordon growth) method is more theoretically sound; the exit multiple method is market-based and more common in banking. Cross-check each: back out the implied multiple from the growth method, and the implied growth rate from the multiple method.

25What terminal growth rate would you use, and how much value should come from terminal value?

No higher than long-run nominal GDP growth of the economy the company operates in — typically 2–3% for developed markets, because no company outgrows the economy forever. Terminal value often makes up 60–80% of a DCF, more for high-growth companies. That is why bankers show sensitivity tables of WACC against terminal growth or exit multiple.

26When is a DCF not appropriate?

When cash flows are highly unpredictable (early-stage startups, pre-approval biotech), negative for a long time, or when debt is part of operations (banks and insurers). Use comps, precedents or sector-specific methods — such as price to tangible book for banks — instead.

4. M&A interview questions

M&A questions test whether you understand why deals happen and how a buyer’s shareholders are affected. Be able to run an accretion/dilution calculation in your head.

27Why do companies acquire other companies?

To grow faster than they could organically, gain market share, enter new geographies or products, acquire technology or talent, and capture synergies. Some deals are defensive — keeping a competitor from buying the asset. The only good reason in the long run: the combined company is worth more than the price paid.

28Walk me through an accretion/dilution analysis.

Project both companies’ net income and add them together. Then adjust for deal effects: foregone interest on cash used, new interest on debt raised, new amortization from asset write-ups, and after-tax synergies. Divide pro forma net income by the new share count, including any shares issued. If pro forma EPS beats the buyer’s standalone EPS, the deal is accretive; if lower, dilutive.

29Is this deal accretive? Work an all-stock versus all-cash example.

Buyer: net income $100, 100 shares, EPS $1.00, share price $20 (P/E 20×). Target: net income $20, purchase price $300 (P/E 15×). No synergies, 25% tax rate.

30What is the quick rule of thumb for accretion or dilution?

For an all-stock deal: accretive if the buyer’s P/E is higher than the P/E paid for the target. For cash or debt: compare the after-tax cost of cash or debt with the target’s earnings yield (the inverse of the purchase P/E). In the example above, the target’s yield is 20 / 300 = 6.7%, above the 3% after-tax cost of cash — so it is accretive. For mixed consideration, use the weighted cost.

31Is an accretive deal always a good deal?

No. EPS accretion is an accounting outcome, not value creation. A buyer with a high P/E can make almost any stock deal accretive while overpaying. The real test is whether the return on the investment beats the buyer’s cost of capital.

32Cash, stock or debt — how does a buyer choose?

Cash is cheapest and gives sellers certainty, but it depletes liquidity. Debt is cheap and tax-deductible, but adds leverage and rating risk. Stock preserves cash and shares risk with sellers, but dilutes ownership — and signals the buyer thinks its shares are fully valued.

33What are synergies, and which kind is more credible?

Cost synergies come from removing duplicate costs — headcount, facilities, procurement. Revenue synergies come from cross-selling or pricing power. Cost synergies are more credible, because management controls them; markets heavily discount revenue synergies.

5. LBO interview questions

In a leveraged buyout, a private equity firm buys a company mostly with borrowed money, repays debt from the company’s cash flow, and sells it after three to seven years. Returns come from three levers: EBITDA growth, debt paydown and multiple expansion.

34Walk me through a basic LBO model.

1. Set the purchase price (entry multiple × EBITDA) and the sources and uses of funds — debt, sponsor equity, fees.
2. Build the pro forma balance sheet at close.
3. Project the income statement and free cash flow over the holding period.
4. Build the debt schedule: mandatory amortization, optional cash sweep, interest.
5. Calculate exit value (exit multiple × final-year EBITDA) and subtract remaining net debt to get equity proceeds.
6. Calculate IRR and money-on-money multiple (MOIC) on the sponsor’s equity.

35Why do private equity firms use leverage?

Debt shrinks the equity check, so the same dollar gain produces a higher percentage return. Interest is tax-deductible, and required debt repayments impose cost discipline. The trade-off is risk: too much debt can bankrupt a company in a downturn.

36What makes a good LBO candidate?

Stable, predictable cash flows; low capex needs; a defensible market position; room to cut costs or improve operations; a strong management team; and a credible exit route. Mature, cash-generative businesses beat high-growth, cash-burning ones.

37Walk me through a paper LBO.

Buy a company with $100 of EBITDA at 10× = $1,000. Finance it with 60% debt ($600) and 40% equity ($400). Over five years, EBITDA grows to $150, and cumulative free cash flow of $300 repays debt. Exit at 10×.

Returns attribution: EBITDA growth adds $500 ($50 × 10), debt paydown adds $300, multiple expansion adds $0 — the full $800 equity gain. Fees are ignored for mental-math speed.

38What IRR does a 2× or 3× return imply?

Memorise this grid. If the holding period lengthens and the MOIC stays the same, IRR falls — time is the enemy of IRR.

39What types of debt fund an LBO?

Private credit funds increasingly provide unitranche loans, which combine senior and junior debt in a single facility.

6. IPO and equity capital markets interview questions

An IPO is the most visible deal a bank runs: months of preparation, two weeks of marketing, and one night of pricing. Interviewers want to see that you understand the process and the trade-offs behind the price.

40Walk me through the IPO process.

1. Bank selection (“bake-off”): the company picks lead underwriters and a syndicate.
2. Due diligence and drafting: banks, lawyers and auditors prepare the registration document — an S-1 with the SEC in the US, a Draft Red Herring Prospectus with SEBI in India, a prospectus approved by the FCA in the UK.
3. Regulatory review: the regulator comments; the draft is revised.
4. Pre-marketing: analyst presentations and early investor feedback shape the price range.
5. Launch and roadshow: management meets investors over one to two weeks while the syndicate builds the order book.
6. Pricing and allocation: the price is set the night before trading, based on demand; shares are allocated.
7. Trading and stabilization: shares list; the greenshoe supports the price if needed.
8. Lock-up expiry: insiders can sell, typically 180 days after a US IPO.

Lock-up terms vary, but most prevent insiders from selling for 180 days, and US rules require the terms to be disclosed in the prospectus (Investor.gov, SEC).

41Why would a company go public — and why not?

For: raise primary capital, give early investors and employees liquidity, create a share currency for acquisitions, and raise the company’s profile. Against: high cost, heavy disclosure, quarterly earnings pressure, some loss of control, and the risk of trading below the IPO price.

42Why are IPOs usually underpriced?

A modest first-day “pop” rewards investors for taking a risk on an unknown stock, builds a healthy aftermarket and protects the issuer’s reputation for future raises. The cost is money left on the table for the company and selling shareholders. Bankers balance both goals.

The cost is real: an SEC analysis of Jay Ritter’s data found middle-market companies left $38.9 billion on the table through first-day underpricing between 2000 and 2017 (SEC).

43What is the greenshoe option?

An over-allotment option that lets underwriters sell up to 15% more shares than the base deal. If the stock trades up, they exercise the option and buy the extra shares from the company. If it trades down, they buy shares in the market to cover the position, which supports the price.

The 15% ceiling dates to 1983, when the NASD (now FINRA) began treating over-allotment options above 15% of an offering as presumptively unfair (FINRA Notice 83-44).

44What are follow-on offerings, block trades and ATM programs?

A follow-on is any equity raise after the IPO — primary (new shares, money to the company) or secondary (existing holders selling). A block trade is a large overnight sale of existing shares to institutional investors. An at-the-market (ATM) program lets a company trickle new shares into the market over time at prevailing prices.

45How do direct listings and SPACs differ from a traditional IPO?

A direct listing floats existing shares without underwriting or a new-money raise — lower fees, but no price support. A SPAC is a listed shell company that raises cash, then merges with a private company to take it public. SPAC activity peaked in 2020–21, collapsed amid regulatory scrutiny and weak post-merger performance, then returned in a smaller, more disciplined form: in 2025, 138 SPACs raised $25.8 billion and made up 40% of US IPOs (FTI Consulting).

7. Deal process interview questions

As an analyst, you will spend more time running processes than debating valuation. These questions test whether you know how a deal actually moves from kickoff to closing — and how the bank gets paid.

46Walk me through a sell-side M&A process.

1. Preparation (4–8 weeks): engagement letter, due diligence on the client, financial model, teaser, CIM, buyer list.
2. First round: contact buyers, sign NDAs, send the CIM, receive non-binding indications of interest (IOIs).
3. Second round: shortlist buyers, hold management presentations, open the virtual data room, circulate a draft purchase agreement.
4. Final bids: receive binding bids with a marked-up agreement; negotiate price and terms.
5. Signing: definitive agreement signed; the board receives a fairness opinion; the deal is announced.
6. Closing: regulatory and shareholder approvals, financing, then funds transfer.

A broad auction typically runs four to six months from kickoff to signing. Closing can take much longer when antitrust review is involved.

47What are the key documents in an M&A process?

48What is a fairness opinion?

A letter from a bank to a company’s board stating that, as of that date, the deal consideration is fair to shareholders from a financial point of view. It is backed by a full valuation analysis and helps directors show they met their fiduciary duties.

49What is a break fee?

A payment the target owes the buyer if it walks away — for example, to accept a superior offer. It compensates the buyer for its costs and deters interlopers; for public targets it is often a low single-digit percentage of equity value. A reverse break fee is paid by the buyer, typically if financing or regulatory approval fails.

50How do investment banks get paid on deals?

• M&A advisory: a monthly retainer plus a success fee at closing, usually a percentage of deal value that declines as deal size rises.
• Equity underwriting: the gross spread. US mid-sized IPOs have historically clustered around 7%; large IPOs pay less.
• Debt underwriting: lower fees — well under 1% for investment-grade bonds, higher for high-yield bonds and leveraged loans.
• Restructuring: monthly fees plus a completion fee when the recapitalization closes.

The 7% figure is well documented. From 2001 to 2016, 96.6% of US IPOs raising $25–100 million paid a gross spread of exactly 7%, versus 50.4% of IPOs raising more than $100 million, according to an SEC analysis of Jay Ritter’s IPO data. Other fee levels vary by market; in an interview, the structure matters more than the exact percentage.

Final word: how to turn these 50 answers into an offer

Knowing the answers is not enough — interviewers score delivery. In your final week before interviews:

• Say every answer out loud until each takes 60 seconds or less, without notes
• Run the depreciation walk-through (Q4), the accretion/dilution example (Q29) and the paper LBO (Q37) on paper, under five minutes each
• Memorise the IRR grid (Q38) and the EV bridge (Q10)
• Learn three recent deals the firm advised on, and walk through one using the sell-side process in Q46
• When you don’t know an answer, reason aloud from first principles instead of guessing

The candidates who win are rarely the smartest in the room. They are the ones who are prepared, precise, and pleasant to work with at midnight. Be that person in every interview.
