Investment banking interviews are technical, fast-paced, and unforgiving. A missed DCF step or a vague "why IB" answer can knock you out in round one.
This guide covers the questions that show up most often — technical (valuation, accounting, M&A/LBO) and behavioral/fit — with direct model answers or frameworks you can adapt. No filler questions, no placeholders.
Here's what you'll find:
- Technical: DCF walkthrough, comparable companies, precedent transactions, 3-statement links, M&A/LBO basics
- Behavioral/fit: "Why investment banking," "Walk me through your resume," deal interest
- A question-category table showing what each type tests
- Answers you can actually use
The Question Categories and What They Test
Interviewers use different question types to probe different things. Knowing the intent behind a question helps you calibrate your answer.
| Category | Example Question | What Interviewers Are Testing |
|---|---|---|
| DCF / Valuation | "Walk me through a DCF." | Mechanics, WACC fluency, terminal value logic |
| Comparable companies | "How do you pick comps?" | Market awareness, judgment on peer selection |
| Precedent transactions | "Why use transaction multiples vs. trading multiples?" | Deal dynamics, control premium intuition |
| Accounting / 3 statements | "How does a $10 depreciation hit flow through?" | Linking statements, accrual accounting grip |
| M&A basics | "Is this deal accretive or dilutive?" | EPS math, deal structure instinct |
| LBO basics | "What drives returns in an LBO?" | Leverage mechanics, IRR drivers |
| Behavioral / fit | "Why investment banking?" | Commitment, clarity of motivation, cultural fit |
| Resume | "Walk me through your resume." | Story, progression logic, deal / finance exposure |
Most first-round screens lean heavily on accounting and valuation. Superdays add more M&A, LBO, and deeper behavioral work.
Technical Questions: Valuation
Walk Me Through a DCF
This is the single most common IB technical question. A clean four-step answer:
- Project free cash flows — typically 5–10 years of unlevered FCF (EBIT × (1 − tax rate) + D&A − CapEx − change in working capital)
- Calculate WACC — the blended cost of debt and equity, weighted by capital structure
- Discount the cash flows — bring each year's FCF back to present value using WACC
- Add terminal value — either a Gordon Growth perpetuity or an exit multiple; discount that back too
- Subtract net debt — to get from enterprise value to equity value (and divide by shares for price per share)
The follow-up question is almost always: *"What's the biggest driver of DCF value?"* Answer: terminal value, which often represents 60–80% of total value — which is exactly why terminal value assumptions matter so much.
Discounted cash flow analysis remains the foundation of intrinsic valuation. Interviewers want to see you understand *why* you discount, not just that you do.
How Do You Pick Comparable Companies?
Comparable company analysis selects peers based on: same industry/sub-sector, similar revenue scale, similar margin profile, comparable growth trajectory, similar capital structure. Geography is secondary.
The real judgment call is how narrow or broad to cast the net. Too narrow and you have three comps with thin trading data. Too broad and the multiples are meaningless. Show that you understand the tradeoff.
Common follow-up: "What's the difference between EV/EBITDA and P/E?" — EV/EBITDA is capital-structure neutral (compares operating performance); P/E includes leverage effects in the denominator, so it's distorted by debt levels.
Why Do Transaction Multiples Usually Come in Higher than Trading Multiples?
Two reasons: control premium (acquirers pay above market price to gain control of the target) and synergies (the buyer bakes anticipated cost or revenue synergies into what they're willing to pay). Trading multiples reflect minority-stake, no-synergy value. Precedent transaction multiples reflect full acquisition pricing.
Technical Questions: Accounting
How Do the Three Financial Statements Link?
This question tests whether you understand how accrual accounting actually works. Here's the linkage:
- Net income (bottom of income statement) flows to retained earnings on the balance sheet and to the top line of the cash flow statement
- D&A is added back on the cash flow statement (non-cash charge)
- CapEx flows from the cash flow statement to PP&E on the balance sheet
- Working capital changes (AR, AP, inventory) tie the income statement to the balance sheet
- Ending cash on the cash flow statement = cash on the balance sheet
The classic follow-up: *"If depreciation increases by $10, walk me through all three statements."*
| Statement | Effect |
|---|---|
| Income statement | EBIT down $10, tax down ~$4 (40% rate), net income down ~$6 |
| Cash flow statement | Net income down $6, D&A add-back up $10 → operating cash flow up $4 |
| Balance sheet | PP&E down $10, cash up $4, net income reduces retained earnings by $6 |
The balance sheet still balances: assets down $6 (−$10 PP&E + $4 cash), equity down $6 (retained earnings).
Technical Questions: M&A and LBO Basics
Is This Deal Accretive or Dilutive?
A stock deal is accretive when the acquired company's earnings yield (earnings / price paid) is higher than the acquirer's earnings yield. It's dilutive when the opposite is true.
In practice, interviewers want you to say: "Compare the cost of the acquisition (interest on debt, dilution from new shares) to the earnings added. If the earnings added exceed the cost, EPS goes up — accretive."
Cash deals using debt complicate this because you compare the after-tax interest cost against acquired earnings. Always ask about the deal structure before answering.
What Drives Returns in an LBO?
Three levers, roughly in order of magnitude:
- Debt paydown — the target's cash flows pay down the acquisition debt over the hold period, increasing equity value mechanically
- Multiple expansion — buying at a lower multiple, selling at a higher one
- EBITDA growth — organic revenue/margin improvement that lifts the exit value
Private equity firms aim for ~20%+ IRR. Leveraged buyouts work when the target has predictable cash flows to service debt and a clear value-creation story to justify the exit multiple.
A common follow-up: *"What makes a good LBO candidate?"* Strong FCF, low CapEx intensity, stable revenue, non-cyclical industry, defensible market position — and ideally an underperforming asset where PE can add value.
Behavioral and Fit Questions
Behavioral performance breaks ties at the Superday. When technical skills are close across finalists, the "why IB" answer and story clarity often determine the offer.
"Why Investment Banking?"
What interviewers are really asking: Are you committed? Do you understand what the job actually is? Can you articulate a coherent path that led you here?
A strong answer has three parts:
- Intellectual interest — transactions, capital markets, corporate strategy at a deal level
- Skill-building — IB as the fastest way to build financial modeling, client management, and cross-sector exposure early in a career
- Specific connection — a deal, a sector, an experience that crystallized the decision
Keep it under 90 seconds. Avoid generic lines like "I want to be in a fast-paced environment" — every candidate says that. A concrete trigger ("I did a summer in consulting, worked on a sell-side due diligence project, and realized I wanted to be on the execution side") is far more memorable.

"Walk Me Through Your Resume"
This is your two-minute pitch. Don't read your resume — tell the story of why each step led logically to the next, ending with why you're sitting in this interview.
Structure: origin → progression → why IB now
- Start with where you're from academically or professionally
- Hit 2–3 roles or experiences that show analytical rigor, deal exposure, or finance skills
- End with a crisp statement of why you're targeting this bank / group specifically
Avoid over-indexing on GPA or coursework. Interviewers care about what you *did* — the internship, the deal, the finance club project.
If you've worked on any transaction (even a student-run deal, a summer M&A project, or a case competition), mention it and be ready to discuss it. For questions like "tell me about a deal you followed," pick one recent public transaction you can speak to intelligently — the rationale, the valuation, the strategic logic.
"Where Do You See Yourself in Five Years?"
IB answer: analyst role → strong performance → associate promotion or business school → long-term career in finance (PE, corporate development, or continuing in banking). Don't say hedge fund unless you're ready to defend it.
The goal is to signal you're committed to the seat, not treating it as a two-year stopover.
FAQ
How long is a typical investment banking interview process?
The process usually runs 4–8 weeks for on-cycle recruiting. A first-round screen (30–45 minutes, behavioral + basic technical) is followed by a Superday — a full day of back-to-back interviews with analysts, associates, VPs, and sometimes MDs. Off-cycle recruiting is less structured but follows the same format.
What technical topics get tested most in first-round IB interviews?
The accounting 3-statement link, DCF mechanics, and basic valuation multiples (EV/EBITDA, P/E, EV/Revenue) appear in almost every first-round screen. LBO and M&A modeling questions are more common in later rounds and for roles with more deal exposure.
Do I need financial modeling experience before interviewing?
Not always — especially for summer analyst roles where banks expect to train you. But you should be able to talk through a DCF, explain how the financial statements connect, and discuss a recent transaction. Strong modeling skills (Excel, 3-statement modeling) are table stakes for full-time analyst and associate roles.
How important is networking for IB recruiting?
Networking is often the deciding factor in whether you get an interview at all. A referral from a current employee can dramatically increase your chances of getting a first-round screen, particularly at bulge-bracket banks where application volume is high. Coffee chats and informational interviews with alumni or current bankers are standard practice — treat them as a key part of your prep, not an afterthought. The CFA Institute also publishes career resources and ethical standards that are useful context for any finance interview. And financial analysts in IB rank among the highest-compensated early-career roles in finance — a useful data point when weighing the effort of recruiting.
One more thing before you walk into that room: most IB interviews are with specific people, not faceless panels. Knowing who you're talking to changes everything — what they've worked on, what they care about, where they went to school. Articuler's Playbook builds a prep brief on your specific interviewer in minutes, drawing from 980M+ enriched professional profiles. It also helps you find and reach current bankers for coffee chats before the interview — with outreach that gets ~8x the reply rate of a generic LinkedIn message.
