How investment banking interviews are structured

For entry-level roles at large US banks, the sequence is a recorded HireVue interview (or a phone screen), then a superday of back-to-back interviews with bankers from analyst up to managing director. Our guide to getting into investment banking covers the timeline and the recruiting side; this page is about what gets asked once you are in the room.

Mergers & Inquisitions sorts every interview question into four categories: your story, “fit” questions, deals and markets, and technicals. That is the right mental model. Junior interviews split roughly evenly between the first three (which test whether they want to work with you) and the fourth (which tests whether you can do the work). Senior interviewers lean toward story and fit; analysts and associates run the technicals, and they get harder as the superday goes on. The twenty questions below are five from each bucket.

Story and fit: the five questions every interviewer asks

1. Walk me through your resume

What it tests: whether you can tell a coherent two-minute story that ends at “and that is why I am sitting here.” It is the first question in almost every interview and it sets the interviewer’s opinion of you before any technical question is asked. Framework: start at the beginning (where you grew up or went to school, one sentence), move through two or three experiences that each taught you something that points toward banking, name the moment you decided on banking, and finish with why this bank and why now. Keep it under two minutes, chronological, and free of anything the interviewer could not follow up on. Rehearse it until it sounds unrehearsed.

2. Why investment banking?

What it tests: whether you know what the job is. Answers about pay, prestige or “exit opportunities” fail because they describe what you want to get, not what you want to do. Framework: give two or three concrete reasons rooted in the work itself: the mix of analytical and client work, the exposure to how companies are valued and financed at the decision-making level, the learning curve compressed into two years, and a specific experience (a class, an internship, a deal you followed) that showed you what the job actually involves. Then acknowledge the hours honestly. Interviewers respect a candidate who knows what they are signing up for.

3. Why this bank, and why this group?

What it tests: whether you did the work, and whether you have talked to anyone there. Framework: one thing about the platform (a sector strength, a recent transaction you can name, the way the group staffs analysts), one thing about the people (name the bankers you spoke with and what they told you, if you have permission), and one thing about fit (why the group’s deal flow matches your interests). Generic praise is worse than nothing. If you networked properly, this question is the payoff.

4. Tell me about a time you failed, or handled a conflict on a team

What it tests: self-awareness and whether you will be tolerable at 2 a.m. on a live deal. Framework: situation, what you did, what happened, what you changed afterward, in that order and in under 90 seconds. Pick a real failure with a real consequence; a “failure” that is secretly a brag reads as evasive. Prepare three stories (a failure, a conflict, a leadership moment) that can be reshaped for the dozen behavioral variants: a time you disagreed with a superior, a time you had too much on your plate, a time you had to persuade someone.

5. Where do you see yourself in five years? (Or: why not consulting or private equity?)

What it tests: whether you will stay past the two-year analyst program, or at least whether you are honest about it. Framework: do not claim you will be a managing director; do not announce you are leaving for private equity in 24 months either. A credible answer is that you want to become excellent at the analyst job, earn the trust to take on more responsibility, and make the associate decision when you have real information. If asked why not consulting, contrast the work: bankers execute transactions with measurable outcomes; consultants write recommendations. Say which you prefer and why.

Accounting: the five questions that filter out the unprepared

6. Walk me through the three financial statements

What it tests: the foundation of everything else. Framework: the income statement shows revenue, expenses and profit over a period, ending in net income. The balance sheet is a snapshot of what the company owns (assets) and owes (liabilities), with the difference as shareholders’ equity; assets always equal liabilities plus equity. The cash flow statement starts with net income, adjusts for non-cash items and changes in working capital to get cash from operations, then adds cash from investing (capital expenditures, acquisitions) and financing (debt, equity, dividends) to arrive at the change in cash. Three sentences, then stop and let them ask the follow-up.

7. How do the three statements link together?

What it tests: whether you understand the statements as a system, which is what modeling requires. Framework: net income from the income statement flows to the top of the cash flow statement and into retained earnings on the balance sheet. Non-cash charges such as depreciation are added back on the cash flow statement and reduce the asset they relate to on the balance sheet. Changes in balance sheet working capital items (receivables, inventory, payables) show up as cash flow adjustments. The ending cash from the cash flow statement becomes the cash line on the balance sheet, which is what makes it balance. Name all four links and you are done.

8. If depreciation goes up by $10, what happens to each statement?

What it tests: whether you can actually trace a change, which is the single most common technical in junior interviews. Framework, at a 25% tax rate: on the income statement, operating income falls by $10 and net income falls by $7.50. On the cash flow statement, net income is down $7.50, but the $10 of depreciation is added back as a non-cash expense, so cash from operations rises by $2.50. On the balance sheet, cash is up $2.50 and property, plant and equipment is down $10, so total assets fall by $7.50; on the other side, retained earnings fall by $7.50 through net income, and the balance sheet balances. Always state your tax rate assumption first; if the interviewer gives you 40%, redo the arithmetic out loud.

9. What is working capital, and why does it matter?

What it tests: whether you understand cash versus profit. Framework: working capital is current assets minus current liabilities; in deal work the operating version excludes cash and debt, leaving receivables, inventory and payables. It matters because a growing company ties up cash in receivables and inventory before it collects, so profit can rise while cash falls. In a DCF, an increase in operating working capital is a use of cash and reduces free cash flow; in an acquisition, the buyer and seller negotiate a working capital target because it changes how much cash the business needs on day one.

10. What is EBITDA, and why do bankers use it?

What it tests: whether you know the metric every comparable-company table is built on, and its flaws. Framework: earnings before interest, taxes, depreciation and amortization, a proxy for operating cash flow that strips out capital structure (interest), tax jurisdiction and accounting choices about asset lives. It lets you compare companies with different leverage and tax positions, and it is the denominator in enterprise value multiples. Its weakness is that it ignores capital expenditures and working capital, so a capital-intensive business can show healthy EBITDA and burn cash. Mention that, and you are ahead of most candidates.

Valuation: the five questions that separate the prepared from the ready

11. What are the three main valuation methods, and when do you use each?

What it tests: the vocabulary of the job. Framework: comparable companies (trading comps) apply the multiples at which similar public companies trade; precedent transactions apply the multiples paid in past acquisitions of similar companies, which include a control premium; a discounted cash flow values the business on its own projected cash flows. Comps are fast and market-based but depend on finding true peers; precedents capture what buyers actually pay but go stale; a DCF is the most rigorous and the most sensitive to assumptions. In practice bankers show all three on a “football field” chart and triangulate.

12. Walk me through a DCF

What it tests: whether you can hold a whole model in your head. This is the technical question with the most follow-ups. Framework: project unlevered free cash flow for five to ten years (EBIT less taxes, plus depreciation and amortization, less capital expenditures, less the increase in working capital). Calculate a terminal value for the years beyond the projection, either by growing the final year’s cash flow at a perpetual rate or by applying an exit multiple. Discount the projected cash flows and the terminal value back to today at the weighted average cost of capital. The sum is enterprise value; subtract net debt (and any preferred stock or minority interest) to get equity value, then divide by diluted shares for a per-share value. Expect the follow-ups to be questions 13 and 14.

13. How do you calculate WACC and the cost of equity?

What it tests: the discount rate, and whether you understand why debt is cheaper than equity. Framework: WACC weights the cost of each source of capital by its share of the capital structure at market values: the equity weight times the cost of equity, plus the debt weight times the cost of debt times one minus the tax rate, because interest is tax-deductible. The cost of equity comes from the capital asset pricing model: the risk-free rate (a government bond yield) plus the company’s beta times the equity risk premium. Be ready to explain beta (sensitivity to the market), why you might unlever and relever it for comparables, and why a higher WACC lowers the valuation.

14. What is the difference between enterprise value and equity value?

What it tests: a concept that trips up more candidates than any other. Framework: equity value is what the shareholders own: share price times diluted shares. Enterprise value is the value of the whole operating business to all capital providers: equity value plus debt, preferred stock and minority interest, minus cash. Enterprise value pairs with metrics available to all investors (revenue, EBITDA, EBIT); equity value pairs with metrics available only to shareholders (net income, so the P/E ratio). The follow-up is usually “can enterprise value be negative?” (yes, if cash exceeds market capitalization plus debt) or “what happens to enterprise value if the company raises debt and holds the cash?” (nothing, the two cancel).

15. Which valuation method usually gives the highest value?

What it tests: judgment, not memorization. Framework: precedent transactions usually come out highest, because acquirers pay a control premium over the trading price; comparable companies tend to be lowest because they reflect minority stakes with no premium. A DCF can land anywhere, because it depends entirely on the growth, margin and discount-rate assumptions, and it is often the highest in practice because projections are optimistic. Say “usually” and give the reason; an interviewer who hears a flat rule will construct the exception.

Deals, markets and transactions: the five that show you follow the business

16. Walk me through a merger model, or: when is a deal accretive?

What it tests: whether you understand what M&A bankers actually model. Framework: a merger model combines the acquirer’s and target’s income statements, adds the cost of the deal (new interest expense if debt-funded, new shares if stock-funded, foregone interest on cash used) and any synergies, and compares the combined company’s earnings per share to the acquirer’s standalone EPS. If pro forma EPS is higher, the deal is accretive; lower, dilutive. The shortcut interviewers want: in an all-stock deal, the acquisition is accretive if the acquirer’s price-to-earnings ratio is higher than the target’s; in an all-cash deal, it is accretive if the target’s earnings yield exceeds the after-tax cost of the debt or cash used.

17. What makes a good leveraged buyout candidate?

What it tests: whether you understand how private equity makes money, which is where half your interviewers want to go next. Framework: stable, predictable cash flows to service debt; low capital expenditure and working capital needs; a strong management team; a defensible market position; assets that can secure borrowing; a purchase price low enough that deleveraging and modest growth produce the target return; and a credible exit in three to seven years. Then explain the mechanics in one sentence: the sponsor buys the company with mostly borrowed money, uses the company’s cash flow to pay the debt down, and sells it, keeping the equity value created by the debt paydown and any growth in earnings or multiple.

18. Tell me about a recent deal you found interesting

What it tests: genuine interest and preparation. Framework: pick one transaction from the last three to six months, ideally in the group’s sector, and know five things: the buyer and seller, the price and the implied multiple, how it was financed, the strategic rationale, and your own view on whether it was a good deal. Two minutes, and be ready for “what would you have done differently?” Prepare two deals in case the interviewer worked on the first one.

19. Pitch me a stock, or: what is your view on the market right now?

What it tests: whether you can form and defend a view with numbers. Framework for the stock pitch: the company in one sentence, the thesis in one sentence (why the market is wrong), two or three supporting points with figures (growth, margins, valuation versus peers), the main risk and why it is manageable, and a price target with a rough basis. For the market view: know where the major indices, the 10-year Treasury yield and the policy rate are, roughly, and have one opinion about what matters most for deal activity. Precision matters less than having looked that morning.

20. A brainteaser or a mental-math question

What it tests: composure and structured thinking, not the answer. These are rarer than the prep industry suggests; Mergers & Inquisitions lists brainteasers among the things not to worry about. Framework: restate the question, say your approach out loud, work it in round numbers, and give an answer with your assumptions attached. For mental math, practice percentages, multiples and quick discounting until they are automatic; that pays off more in the paper LBO questions private equity interviews use (see our private equity interview questions guide, which works one through) than in banking interviews themselves.

How to prepare in four weeks

1. Week 1: story and fit. Write the two-minute resume walk and the three behavioral stories. Record yourself answering questions 1 through 5 on camera, because the HireVue round is exactly that.
2. Week 2: accounting and the statements. Learn questions 6 through 10 until you can trace any change (depreciation, inventory, a debt raise, a stock buyback) through all three statements without notes. This is the week where a structured question bank saves the most time.
3. Week 3: valuation and transactions. Questions 11 through 17. Build one simple DCF and one accretion-dilution calculation in a spreadsheet yourself; the questions become easy once you have done the arithmetic.
4. Week 4: bank-specific work and mocks. Prepare two deals and a stock pitch for each bank. Do at least two mock interviews with someone who has been through a superday, and ask them to push follow-ups until you break.

Where to get question banks and worked answers

Twenty questions is the spine; volume is what makes the follow-ups routine. The options, by what they are good for:

Our honest routing: the free WSO page plus this guide gets you through a first-round screen. If you have superdays scheduled, the WSO course is the one we would buy, because the follow-up depth is what superdays test. If your accounting is genuinely weak, an interview bank will not fix it; CFI or Wall Street Prep will. Our Wall Street Oasis review covers the course prices and the sale mechanics.

Mistakes that end interviews

• Answering the technical without stating assumptions. Tax rate, all-cash versus all-stock, which working capital definition. Say it first; it shows you know the answer depends on it.
• Talking past the answer. Give the answer in two or three sentences and stop. Interviewers want to steer; a monologue removes their ability to.
• Guessing on a deal or market question. If you do not know the 10-year yield, say you do not have the exact number and give your best estimate with a range. Confident wrong numbers are remembered.
• A story that does not match the resume. Every experience you mention will be probed. If you cannot discuss it for five minutes, cut it.
• Preparing only questions. Superday interviewers ask follow-ups until you reach the edge of your knowledge. The goal is to move that edge, not to memorize the first answer.

Frequently asked questions

What are the most common investment banking interview questions?

Walk me through your resume, why investment banking, why this bank, the three financial statements and how they link, the depreciation-goes-up question, walk me through a DCF, enterprise versus equity value, the three valuation methods, and a recent deal. The twenty above cover the variants.

How technical are investment banking interviews?

At the analyst level, roughly half the questions are technical, and they get harder through a superday. You need accounting, valuation and basic M&A and LBO concepts cold, but not modeling ability; the internship teaches that.

How do you answer “why investment banking”?

With two or three reasons rooted in the work itself and one experience that showed you what the job involves, then an honest acknowledgment of the hours. Pay, prestige and exit opportunities are the answers that fail.

How do you walk through a DCF in an interview?

Project unlevered free cash flow for five to ten years, calculate a terminal value by perpetual growth or an exit multiple, discount everything at WACC to get enterprise value, subtract net debt for equity value, and divide by diluted shares. Expect follow-ups on WACC and terminal value.

How long should you prepare for an investment banking interview?

Four focused weeks is enough if your accounting foundation exists: one week each for story and fit, accounting, valuation and transactions, then bank-specific prep and mock interviews. Start earlier if you have never traced a change through the three statements.

Is a paid question bank worth it?

If you have superdays scheduled, yes; the follow-up depth is what they test, and the WSO course’s 7,500-question bank with worked answers is the most-used option. For a first-round screen, the free WSO page plus this guide is enough.
