The Complete Deal Walkthrough Guide for Investment Banking Interviews

Stock pitches used to be a rite of passage in banking interviews. These days they come up less and less. The deal walkthrough has gone the other way. It is a staple of both investment banking and private equity interviews, and if you are recruiting for a banking seat, you should treat it as a near-certainty rather than a maybe.

Here is the moment you are preparing for. Somewhere in the conversation, your interviewer leans back and says, "Can you tell me about a deal our team has worked on?" What happens in the ninety seconds that follow tells them more about your preparation, your commercial instincts, and your ability to think like a banker than almost any other question they could ask. The facts of the deal are public. Anyone can read a press release. What they are actually grading is the part that is not in the press release: your judgment.

This guide gives you the full framework for answering that question well. It is a five-part structure for any walkthrough, threaded from start to finish through one real deal so you can watch each piece fit together into a single coherent answer. At the end there is a power move that signals, in one sentence, that you prepared harder than anyone else in the pipeline.

A note on scope before we start. In banking, the deals you walk through are M&A. In private equity, the equivalent is an LBO, walked through almost identically. This guide is written for the IB version, an M&A deal, but the structure is shared. If you are also recruiting for PE, nearly everything here transfers, and I will flag the few places where the PE answer differs.

What the deal walkthrough is really testing

Your interviewer will expect you to have one or two deals prepared. Ideally, at least one of them is a deal their own team or firm has worked on. A strong second choice is a deal that fits the team's industry or product group (for banking) or the firm's investment strategy (for PE). Knowing a deal they personally touched is the single highest-leverage piece of prep you can do, because it tells them you researched them, not just the asset class.

Three things separate a good walkthrough from a forgettable one:

• You know the deal cold.
• You can deliver a coherent, flowing description without stumbling.
• You have an insightful, well-researched opinion on it.

Notice where the real test sits. The first two are about preparation and polish. The third is about judgment, and it is the one that wins or loses the interview. The structure below has five parts, but they are not equal. Four of them are essentially transcription from public documents. The fifth, "Your Perspective," is the only part the documents cannot hand you. We will weight the guide accordingly.

One practical constraint to keep in mind throughout: the whole walkthrough should run about 1.5 to 2.5 minutes when spoken aloud. That is the delivery target, not a limit on your prep. You want to research far more than you say, then compress it into a tight, rehearsed ninety seconds to two and a half minutes that never drags.

Start preparing now

The best time to start is before you have an interview on the calendar. The most efficient way to prepare is to find an acquisitive company and follow it on a weekly basis. If you already know a company well, the incremental effort to prepare a walkthrough on one of its deals is small. You are not starting from a blank page each time. You are drawing on a story you have been tracking for weeks.

If you cannot do that, it is fine. You can always prepare these questions once you receive notice of an interview. The point is simply that the candidates who sound effortless on deal walkthroughs are usually the ones who built up familiarity over time rather than cramming a press release the night before.

Where the material comes from

Most of the content in your walkthrough is taken directly from two documents: the deal's press release and the definitive proxy statement. You do not need inside information. You need to know where to look and what to pull.

Finding them is straightforward. Use these search templates:

The proxy statement is the richer document, and the section you want is usually called "Reasons for the Merger." A word of warning here, because not every proxy is equally useful. Take L3Harris's acquisition of Aerojet Rocketdyne. The "Reasons for the Merger" section sits on page 36, but in that case the stated reasons are not especially insightful. They relate more to the mechanics of the M&A process than to the genuine strategic rationale. That is a common trap. The document gives you reasons, but they are procedural boilerplate, not the commercial logic you can build an opinion on.

For contrast, look at AMD's merger with Xilinx. That is a high-quality proxy statement, and pages 89 to 97 provide plenty of material you can use for both the "Strategic Rationale" and "Your Perspective" sections. That is what you are hunting for: a document with enough substance to fill the two sections that actually matter.

This leads to a simple screening rule when you are choosing which deal to prepare. Before you commit, make sure the press release or proxy contains enough to address both of those key sections well. If you cannot find at least four reasons for the acquisition, and there is no strong reason to stick with that particular deal, choose a different one. A deal you cannot form a rich opinion about is a deal that will leave you exposed the moment your interviewer asks a follow-up.

If the rationale is not in the press release or the proxy, you have options before you abandon the deal. Dig into SeekingAlpha, or news outlets like the Wall Street Journal, the Financial Times, the New York Times, and Bloomberg. Often the strategic logic that the legal documents bury is spelled out plainly by a journalist or an analyst.

Two types of walkthrough

There are two versions of this question, and they change one part of your answer.

A deal they've done. This is the most common type. You are walking through a transaction the team or firm advised on, which you researched but did not personally work on. Here you do not talk about "Your Role," because you had none. You give everything else, and you give "Your Perspective."

A deal you've done. This is when the deal is on your resume and they ask you to walk through it. Now you provide both "Your Role" and "Your Perspective," because you were actually in the room.

Hold on to that distinction. The five-part framework below is shared across both. The only moving part is whether the "Your Role" module is switched on. For PE candidates, the same split applies cleanly: a deal the firm did versus a deal you worked on.

The five-part walkthrough

Every walkthrough, whichever type, follows the same five beats:

1. Deal Background
2. Business Description & Financial Parameters
3. Strategic Rationale
4. Your Perspective (and, for your own deals, Your Role)
5. Deal Outcome

To make this concrete, we will run a single real deal through all five sections. When I interviewed at Moelis, the deal I walked through was Boyd Gaming's acquisition of Pala Interactive. The scripts below are the actual answers from that walkthrough, and watching one deal cohere from background to outcome is the whole point. A walkthrough is not five disconnected facts. It is one story told in five moves.

1. Deal Background

Start by orienting your interviewer. There are four things to cover, in this order:

• Type of transaction (M&A, most likely)
• The bank's role (did they advise the buyer or the seller?)
• Who was involved (who is the buyer, who is the seller?)
• Size of the transaction

These four facts let the listener build a mental picture in seconds: what kind of deal it is, which side of the table the bank sat on, who the players are, and how big it was. Getting the bank's role right matters more than it looks. This is a deal their team advised on, so mixing up buy-side and sell-side advisory is an unforced error that undercuts the impression that you did your homework.

Here is the exact answer I gave at Moelis:

Notice all four boxes get ticked in two sentences. It is an M&A deal. Moelis advised Boyd, the buyer. The counterparties are Boyd and Pala, with Goldman on the other side. The size is $170mm, and there is even a detail on how it was funded, with cash on hand and revolver borrowings, which signals you read past the headline number.

One adjustment to make when the seller is a public company. In that case you should also mention the premium the buyer paid over the seller's trading price, because for a public target the premium is the most scrutinized number in the deal. It shows you understand that acquirers pay above the undisturbed share price to win control. The structure looks like this:

The bracketed figures there are placeholders to fill with your own deal's numbers, not data from the Boyd transaction. Pala was private, which is why the premium does not appear in the real script above. There was no public closing price to pay a premium over.

2. Business Description & Financial Parameters

Once the deal is framed, explain what the buyer and seller each do. One to two sentences on each business is enough, and you should fold in the financials that convey size, growth, and profitability. You are giving your interviewer a sense of relative scale, because the scale itself often tells the story.

For the buyer:

For the seller:

Look at what the financials reveal on their own. A $6b-market-cap acquirer with $3.4b of revenue is buying a private company with roughly $6mm of revenue. That size mismatch tells you immediately this is not a merger of equals. It is a large operator acquiring a small company for its capability, in this case Pala's iGaming technology and expertise, rather than for its earnings.

There is also a small lesson in how a private target gets handled. Pala does not publish financials, and rather than waving that away, the answer names it directly and then volunteers a Googled revenue figure. That move does two things. It is honest about the information limit, and it shows you were resourceful enough to size the target anyway.

3. Strategic Rationale

This is where you give the reasons the deal happened, from the perspective of both the buyer and the seller. Covering both sides is what proves you understand the transaction as a negotiation with logic on each side, not a one-sided event.

You will find these reasons in the press release or, more often, in the proxy. If they are not in either, go back to SeekingAlpha or the news outlets mentioned earlier. And if you cannot assemble at least four reasons, reconsider the deal entirely, per the screening rule above.

Aim for two to three reasons per party. That is enough to sound thorough without running long. Here is the part most candidates miss: if you find more reasons than that, do not spend them all here. Save the extras as ammunition for "Your Perspective." Holding some back is deliberate, because it lets your opinion sound freshly analyzed later rather than a rerun of what you just said.

Here is the rationale for Boyd and Pala:

See the construction. The first two paragraphs are the buyer's logic: customer data, iGaming expertise, and control over the technology and economics. The third paragraph flips to the seller's logic: access to Boyd's customers, capital to fund the next growth phase, and good timing around the repeal of PASPA. By the end, the listener understands why each side said yes.

4. Your Perspective, and Your Role

This is the section that wins the interview. I'll be blunt: "Your Perspective" is the most important part of the entire walkthrough, because it is the only place that shows how you think as a banker. Everything before it is gleaned straight from the press release and the proxy. This is the part you cannot copy.

Your Perspective

The question you are really answering is simple: What do you think of this deal? They are testing whether you can reason like a banker or a PE professional. Your answer should cover why you do or do not think the deal should have been pursued, and what you think the combined company will look like.

Mechanically, it is close to the Strategic Rationale section, with one change. You begin your sentences with "I think…" or "In my opinion…" The substance shifts from reporting the stated reasons to advancing your own view.

Your job is to make the interviewer believe you have done real analysis on this deal, or at least researched it extensively. Sometimes you genuinely will have. Other times you will lean on those extra reasons you held back from the Strategic Rationale section. Most often it is a combination of the two.

If you want to go deeper, the definitive proxy statement is a goldmine. It contains the analyses each financial advisor completed: the assumptions behind their DCF if one was used, the comparable companies and precedent transactions they included, and the other methods they used to reach their valuation. This material usually sits under a heading like "Opinion of [Company X's] Financial Advisors," and it contains both the buyer's and the seller's advisors' opinions. Reading it gives you genuine analytical detail to draw on.

The process I typically used was about two hours scrolling through Google, compiling reasons beyond the ones I would use for Strategic Rationale. With enough research you can build a solid list. Then you pick the reasons that seem most promising or most complex, because the goal here is to impress.

Here is the perspective I gave on Boyd and Pala:

It is worth slowing down to see why this answer lands, because it is a model of what "insightful and well-researched" actually means. It stacks four distinct arguments rather than restating one:

1. A regulatory tailwind with a motive attached, where governments relax iGaming rules to capture tax revenue.
2. Revenue synergies from cross-sell and up-sell between the two businesses.
3. A market-share angle, where mobile technology lets Boyd reach customers who would never have walked into a physical casino.
4. An industry-shakeout thesis, where only the largest players can absorb rising customer-acquisition costs, so smaller competitors get bought or fail.

Then comes the detail that signals real homework: the LTV/CAC comparison, roughly 7x in iGaming against about 4x for most technology subsectors. A specific, researched number like that is the difference between an opinion that sounds informed and one that sounds improvised. That is the bar you are aiming for.

Your Role

If the deal is one you actually worked on, lead with "Your Role" before you give your perspective. Here you describe your contributions to the deal. You can talk about the due diligence you performed, whether business, financial, industry, or otherwise. You can talk about the model you built or a specific analysis or write-up you produced, such as a market sizing, a DCF, comps, precedents, an LBO, or company and industry background. You can also talk about whether you delivered the presentation, who you delivered it to, and how they responded.

One to two sentences is enough, and then you move into "Your Perspective" exactly as you would for a deal they've done.

A warning that comes with this section. You will likely get follow-up questions on it, because this is the part you personally own. Expect to be asked about your DCF assumptions, how you assessed the competitors, how you sized market share and end-market demand, and which comps you used. The rule that follows is simple: only claim what you can defend under questioning. There is nothing worse than naming an analysis you cannot then explain.

5. Deal Outcome

The final beat has two flavors, and which one applies depends on the deal.

The retrospective update. If some time has passed since the acquisition closed, you can give a brief update on how it has actually gone. Have the synergy targets been met? How has the combined company performed? Were there integration issues? What has management said about the progress? What is the street saying? Has the strategic rationale come to fruition? Keep this to one or two sentences, simple and brief. If not much time has passed since completion, or if the companies are private, you can simply skip it. That is exactly the case with Boyd and Pala. The deal was recent and the target private, so there is no retrospective to give, which is why the real walkthrough goes straight to the forward-looking view.

The forward projection. This is how you think the deal will perform going forward, and it is where you close. For an M&A deal, frame it in terms of revenue growth and margins:

If you are interviewing for private equity and walking through an LBO, the framing shifts from operating performance to returns, because returns are how PE deals are judged:

The contrast is the lesson. The M&A close talks about revenue growth and margins because that is how an acquirer's success is measured. The LBO close talks about doubling the investment and an IRR of 20 to 25% because a sponsor lives and dies by return on capital. Match the metric to the audience.

The two-deal power move

Here is the flourish that sets the most prepared candidates apart. If you have extra time, prepare two deals for every interview rather than one. Then, when the interviewer asks, "Could you tell me about an M&A deal our team has worked on?", you answer:

and you walk them through it.

Why this works is worth understanding. In a single sentence, you reframe yourself. You are no longer a candidate who prepared a deal. You are a candidate who studies the team's deal flow closely enough to have an opinion about which of their transactions is most interesting. It signals that you went well beyond the normal expectation, and it does so without sounding like a boast, because it is delivered as a natural aside on the way into your answer.

There is one condition, and it is non-negotiable: only do this if you actually have both deals prepared. They may well ask you to walk through both, and getting caught having name-dropped a second deal you cannot deliver turns a power move into a liability.

Putting it together

Strip the walkthrough down and the structure of the test becomes obvious. The Deal Background, Business Description, Strategic Rationale, and the retrospective half of the Deal Outcome are all transcription. They come straight out of the press release and the proxy, and any prepared candidate can deliver them. The interview is not won there. It is won on "Your Perspective," and on "Your Role" when the deal is your own, because those are the only parts that reveal how you actually think.

So spend your prep accordingly. Start now, ideally by following an acquisitive company week to week so familiarity builds on its own. Source the facts from the press release and the definitive proxy, screen out any deal you cannot find at least four solid reasons behind, and hold a few of those reasons in reserve. Then rehearse the whole thing to a tight 1.5 to 2.5 minutes. Most of all, walk in with a real, well-researched opinion, because when your interviewer leans back and asks about a deal their team did, your judgment is the thing they are actually grading.
