How to Answer "Walk Me Through a Deal" in an Investment Banking Interview

"Walk me through a deal you've followed" is one of the most predictable questions in investment banking interviews, especially in capital markets. Even so, it trips up many prepared candidates. The usual failure isn't a lack of knowledge. It's structure: candidates either recite a press release or wander through details until the interviewer cuts in.

This guide gives you a five-part framework, two full sample answers (one IPO, one bond deal) and the follow-up questions to expect. The sample deals are hypothetical, so you can see the structure without copying anyone else's deal.

What the interviewer is testing

The question looks open-ended, but the interviewer is scoring four things:

1. Genuine interest. Did you actually follow a deal, or did you read a headline last night?
2. Understanding of how deals work. Can you explain the structure and process, not just the outcome?
3. Judgment. Can you say why the deal was done that way and whether it worked?
4. Communication. Can you deliver a clear answer in about 90 seconds, then go deeper when asked?

The fourth one matters more than most candidates expect. In capital markets you'll constantly summarize deals for senior bankers and clients. This question is a preview of that skill.

The 5-part framework: Context → Structure → Process → Outcome → Takeaway

1. Context (about 15 seconds)

Who's the issuer, and why did they raise money or do the deal now? Mention the business in one line, the purpose of the transaction (growth capital, refinancing, a sponsor exit, an acquisition), and the market backdrop that made the timing work.

2. Structure (about 20 seconds)

What exactly was sold? For equity: the size, the primary/secondary split, the price range and final price, and any greenshoe. For debt: the size, tenor, coupon or spread, and any notable features (call protection, covenants, multiple tranches).

3. Process (about 20 seconds)

How was it marketed and priced? For an IPO: the roadshow, the range, bookbuilding and where it priced versus the range. For a bond: initial price thoughts, guidance and final spread, plus the book size if it was disclosed publicly.

4. Outcome (about 15 seconds)

How did it trade, and was it a success for whom? An IPO up 40% on day one is a win for investors but may mean the issuer left money on the table. A bond that tightened sharply after pricing suggests demand was strong, and perhaps the concession was too generous.

5. Takeaway (about 10–15 seconds)

Close with one insight: what the deal says about the market, the sector or deal execution. This is where you show judgment, and it's what interviewers remember.

Total: roughly 90 seconds. Then stop and let them ask follow-ups.

Sample answer #1: a hypothetical IPO

Project Quill is a hypothetical software IPO used for illustration.

"I followed the IPO of Quillfeather, a mid-sized software company. Context: it was growing quickly and wanted primary capital to fund expansion, while early investors wanted partial liquidity. The window was open after several software IPOs had traded well.

Structure: the base deal was 15 million shares, 10 million primary and 5 million secondary, with a standard 15% greenshoe of 2.25 million shares. The initial range was $23 to $26, which implied a discount to where comparable software companies traded.

Process: after a roadshow of about a week, demand was strong and heavily price-insensitive, so it priced at the top of the range at $26.

Outcome: it closed the first day at $31, up about 19%. That's healthy, but at roughly $5 a share on 15 million base shares it suggests about $75 million was 'left on the table' compared with pricing at the day-one close. Because it traded above the offer, the underwriters would exercise the greenshoe rather than buy shares back.

Takeaway: for me it showed the balance between maximizing proceeds and building an aftermarket. The company accepted a modest pop in exchange for a stable shareholder base, which matters if it wants to do a follow-on later."

Why it works: each section is short, the numbers are consistent (15M base shares, 15% greenshoe = 2.25M shares), and the takeaway shows judgment. For more on the greenshoe mechanics, see Greenshoe Option Explained.

Sample answer #2: a hypothetical bond deal

Project Harbor is a hypothetical investment-grade utility bond used for illustration.

"I followed a $750 million 10-year bond from Marrowstone Utilities, a hypothetical investment-grade utility. Context: it was funding grid investment and refinancing a maturing bond, and credit markets were stable with strong demand for high-grade paper.

Structure: a single 10-year senior unsecured tranche off its existing shelf.

Process: the desk announced initial price thoughts at Treasuries plus 140 basis points, moved to guidance at plus 120 as the book built, and priced at plus 115, a 25 basis point tightening. With the 10-year Treasury at 4.00% in this example, that's a 5.15% yield, and the coupon was set at 5.125%, so the bonds priced just below par.

Outcome: interpolating the issuer's existing curve put fair value around T+110, so the new issue concession was about 5 basis points. That's modest and suggests strong demand.

Takeaway: the tightening from initial price thoughts to final spread shows how much order book momentum matters in DCM, and that a well-known issuer can price close to its curve."

Follow-up questions to expect

Interviewers will often push on one part of your answer. Prepare for:

• "Why did they choose an IPO (or bond) rather than another option?"
• "Why that tenor, size or structure?"
• "Who do you think the main investors were?"
• "Was it priced correctly? How would you know?"
• "What would you have done differently?"
• "How has it traded since?"
• "How does this deal compare with others in the sector?"

If you don't know a detail, say so and reason through it: "I didn't see the allocation breakdown, but given the size and sector, I'd expect it was mostly long-only funds." That's better than guessing a number.

Common mistakes

1. Choosing a deal you can't defend. Pick one you've genuinely followed and can discuss for five minutes.
2. Reciting the press release. Facts without the why don't show judgment.
3. Going too long. Two minutes of uninterrupted detail is a red flag. Aim for 90 seconds.
4. Getting numbers wrong. Check your figures against public sources. Inconsistent numbers undermine credibility quickly.
5. Sharing confidential information. If you worked on a deal at an internship, discuss only what's public. Interviewers are testing your discretion as well as your knowledge.
6. No takeaway. Ending with "...and it closed" wastes your best chance to stand out.

How to prepare your deals

• Prepare two or three deals: at least one in the product area you're interviewing for (an IPO or follow-on for ECM; a bond for DCM; an LBO financing for LevFin) and ideally one recent.
• Use public sources: company filings and press releases, the issuer's investor relations site and reputable financial news.
• Write a one-page summary for each using the five-part framework, then practice it out loud with a timer.
• Prepare the "why" behind every choice: timing, size, structure and pricing.
• Rehearse the follow-ups, especially "Was it a success?" and "What would you change?"
