Key Takeaways

A corporate development case study interview asks you to analyze an acquisition or partnership, value it, and deliver a clear buy or pass recommendation backed by numbers.

The most common format is a 30 to 60 minute on-site case where you recommend for or against acquiring a target and name a price

You are judged on strategic rationale, valuation, synergies, and a crisp recommendation, not just the model

Value the target three ways: a discounted cash flow analysis, comparable company multiples, and precedent transaction multiples

Always pressure test whether the company should build, buy, or partner before assuming an acquisition is right

Corporate development is a buy-side role, so form your own view on whether the deal is good, not just how to execute it

According to Glassdoor, corporate development analysts earn roughly $115,000 per year on average as of 2026

What Is a Corporate Development Case Study Interview?

A corporate development case study interview is an exercise where you are handed a potential acquisition, joint venture, or partnership and asked to analyze it and recommend whether your company should do the deal. You evaluate strategic fit, value the target, estimate synergies, and defend a clear recommendation, usually in 30 to 60 minutes.

Corporate development is the in-house team that drives a company's growth through deals rather than through day-to-day sales. They source and execute acquisitions and divestitures, structure joint ventures, and decide which markets the company should enter next.

This is why the case study sits at the center of the process. The team needs to see that you can think like an owner of the business, put a defensible number on a target, and tell them whether the deal makes the company more valuable over the long term.

Do not confuse this role with business development, which focuses on sales and partnerships to grow revenue organically. A business development case study interview tests growth and partnership strategy, while a corporate development case almost always centers on a specific transaction and its price.

How Is Corporate Development Different From Consulting and Banking Cases?

A corporate development case differs from a consulting case in scope and from a banking interview in mindset. Consulting cases cover a wide range of problems, while corporate development cases almost always focus on a single deal and lean harder on valuation and modeling.

The structured thinking is the same, though. The candidates who break a messy deal into clear buckets and communicate cleanly are the ones who get offers, which is exactly what strong case interview frameworks train you to do.

The contrast with investment banking is mindset. In banking you execute a deal for a client, but in corporate development you sit on the buy-side and must form your own view on whether the company should do it at all. Saying "this is how I would run the process" is not enough. You have to say "I would do this deal, or I would walk away, and here is why."

That buy-side judgment is the closest cousin to a private equity case interview, where you also weigh whether a target is worth owning. The difference is that corporate development judges a target through the lens of one parent company and its long-term strategy.

What Are the 4 Types of Corporate Development Case Studies?

There are four common formats, ranked from most to least common: a short on-site acquisition case, a longer take-home case, a deal-experience walkthrough with no model, and a joint venture or partnership model. Knowing which one you face changes how much depth and polish the team expects.

Format	Time	What it tests	How to win
On-site acquisition case	30 to 60 minutes	Quick valuation and a buy or pass call	Keep the math simple and reach a clear answer fast
Take-home case	A few days to a week	Full valuation, market research, and a deck	Go deep on market research, not on model complexity
Deal walkthrough	One interview	Your judgment on past deals you worked on	Have a point of view on whether each deal was smart
Joint venture model	30 to 90 minutes	Excel mechanics and deal structure math	Get the formulas right and the structure clean

The on-site acquisition case is the one to prepare for first. You get a target, a few financials, and a short window to recommend whether to buy and at what price, often followed by a quick presentation to the team.

The take-home rewards range over speed. Build a clean but simple model, then spend your extra time on market research, and consider proposing one or two alternative targets that might fit the strategy even better.

The joint venture model is closer to an Excel test than an investment debate. You are graded on whether you can structure upfront payments, incentive fees, and performance penalties correctly and calculate the right numbers.

How Do You Approach a Corporate Development Acquisition Case?

Approach every acquisition case the same way: clarify the goal, then work through strategy, valuation, synergies, risks, and a recommendation. A repeatable sequence keeps you from drowning in numbers and missing the actual question, which is whether this deal makes the company better off.

Here is the sequence I teach candidates to run, in order.

Clarify the objective: ask why the company is considering this deal, since the answer shapes everything else
Test the strategic rationale: decide whether the target actually advances the company's strategy
Assess the market: check whether the target plays in an attractive, growing space
Assess the target: look at its revenue, margins, customers, and competitive moat
Value the target: triangulate a price range from a few valuation methods
Quantify synergies: estimate the cost and revenue gains from combining the two companies
Weigh the risks: flag execution, integration, and overpayment risk honestly
Recommend: give a clear buy or pass call, a price, and the conditions that would change your mind

Notice that valuation is only step five. Candidates who jump straight to a model before they understand the strategic logic almost always lose, because they end up pricing a deal that should never happen in the first place.

This is where structured thinking earns its keep. If you want to sharpen the structured approach these cases reward, my case interview course walks you through proven strategies in as little as 7 days.

How Do You Value the Target Company?

Value the target with three methods and triangulate them into a range. A discounted cash flow captures intrinsic value, comparable company multiples show what similar businesses trade for, and precedent transactions show what buyers have actually paid for similar companies.

Method	What it measures	Watch out for
Discounted cash flow	Intrinsic value from projected cash flows	Very sensitive to growth and discount rate
Comparable companies	Value from multiples of similar public firms	No two companies are truly identical
Precedent transactions	Multiples buyers paid in past deals	Includes a control premium that inflates value

In a short on-site case, keep it simple. Project a few years of cash flows, apply a reasonable multiple to earnings, and sanity check the result against what comparable deals have gone for.

Then add synergies, because the value of the target to your company is usually higher than its standalone value. Cost synergies come from removing duplicate functions and gaining scale, and revenue synergies come from cross-selling and reaching new customers.

You should also know accretion and dilution. A deal is accretive when the combined company's earnings per share rise after the acquisition and dilutive when they fall, and corporate development teams care a great deal about which one your deal produces.

Be ready to defend the returns too. If the interviewer asks for one, a quick net present value or internal rate of return check shows whether the price you are paying clears the company's required return.

None of this works if your arithmetic is shaky under pressure. Drilling case interview math until you can multiply, estimate, and convert percentages quickly is the cheapest edge you can buy before one of these interviews.

Should the Company Build, Buy, or Partner?

Before you price an acquisition, ask whether buying is even the right move. A company can build the capability itself, buy it through an acquisition, or partner through a joint venture or alliance, and the best corporate development candidates raise this question without being prompted.

Building makes sense when the company has the time, talent, and capital to develop the capability in-house and wants to keep full control. It is slower but avoids integration headaches and a control premium.

Buying makes sense when speed matters, the target owns something hard to replicate, or the window to enter a market is closing. This is often the right call when a company wants instant scale or a defensible technology, and it overlaps heavily with the logic of a market entry case interview.

Partnering makes sense when full ownership is too expensive or too risky, but both sides gain from working together. Joint ventures let two companies share cost, risk, and upside without one swallowing the other.

Worked Example: Should You Acquire a Competitor?

Let's walk through a simplified on-site case from start to finish. The numbers below are illustrative and rounded to keep the logic clear.

Interviewer: Our client is a mid-sized software company. A smaller competitor is for sale with $50 million in revenue and a 20% profit margin. Should we acquire it, and what would you pay?

You: First, I want to understand the goal. Are we buying for the technology, the customers, the talent, or to remove a competitor? Let's say the main goal is to acquire its technology and customer base to speed up our own product roadmap.

Start with strategic fit. The target sells to the same customers, so its product can be cross-sold through your existing sales team, and its technology shortens a roadmap that would otherwise take years to build.

Now value it. The target earns $10 million in profit on $50 million of revenue, and let's say comparable software companies sell for 10 times profit. That puts a standalone value near $100 million.

Next, layer in synergies. Assume you can cut $5 million of duplicate costs each year and add $3 million of new profit from cross-selling, for $8 million in annual synergies that are worth real money to your company but not to a standalone buyer.

Those synergies justify paying above the standalone price. If you pay $130 million, you are paying a premium, but the $8 million of yearly synergies and the strategic value of the technology can support it if integration goes well.

You: My recommendation is to acquire the target at up to roughly $130 million, contingent on confirming the customer overlap and the technology in due diligence. I would walk away above that price, because the deal would only work if every synergy lands perfectly.

That is what a strong answer looks like. You moved from goal to strategy to value to synergies to a specific number and a clear condition, all without a complicated model.

What Behavioral and Fit Questions Should You Expect?

Expect questions about your deal experience, your reasons for wanting the role, and your ideas for acquisitions in the company's industry. Teams want proof that corporate development is a real choice for you, not a fallback after another path did not work out.

The most important question is some version of "why corporate development?" Lead with the long-term nature of the work and your desire to grow one company over time rather than serving a rotating set of clients.

You will also get asked for acquisition or partnership ideas for the company. Research its recent deals, read its earnings commentary, and come in with one or two specific targets and a sentence on why each would make the company more valuable.

Prepare your stories the same way you would for any structured behavioral round. The discipline behind a strong consulting fit interview answer applies directly here, and my fit interview course covers how to structure those answers in a few hours.

Tips to Ace Your Corporate Development Case Study Interview

Tip #1: Lead with the recommendation, then support it

Corporate development teams make decisions, so they want your answer up front. State whether you would do the deal and at what price, then walk through the logic that got you there.

Tip #2: Keep the model simple under time pressure

In a 30 to 60 minute case, nobody expects a three-statement model. A clean cash flow projection and one or two multiples beat a sprawling spreadsheet you cannot finish or explain.

Tip #3: Always separate standalone value from synergy value

The price you can justify depends on what the target is worth to your specific company. Show the standalone value first, then add synergies to explain why you can pay a premium and still win.

Tip #4: Name the risks before the interviewer does

Calling out integration risk, customer concentration, or the danger of overpaying signals maturity. It tells the team you think like an owner who has to live with the deal, not a banker who moves on after the close.

Tip #5: Practice presenting your answer out loud

You will often present your recommendation to the team, so rehearse explaining a deal in a few clear minutes. Running timed mock cases with feedback is the fastest way to get there, which is exactly what targeted interview coaching is built for.

What Are the Most Common Mistakes?

The biggest mistakes are modeling before thinking, ignoring synergies, and never committing to a number. Each one signals that you do not yet think like a member of the deal team.

Diving into a spreadsheet before you understand why the company wants the deal

Valuing the target on a standalone basis and forgetting the synergies that justify a premium

Hedging at the end instead of giving a clear buy or pass call and a price

Treating the case like a banking exercise and never forming your own view of the deal

Overcomplicating the math and running out of time before reaching a recommendation

Avoiding these traps is mostly about discipline. Having coached hundreds of candidates, I can tell you the ones who slow down for thirty seconds to clarify the goal almost always outperform the ones who race to the numbers.

Acing a corporate development case study interview comes down to one habit: reason from strategy to value to a clear recommendation, and the single most useful thing you can do before the interview is run timed mock cases until that sequence feels automatic.

Frequently Asked Questions

What is tested in a corporate development case study interview?

A corporate development case study interview tests strategic thinking, valuation, financial modeling, and communication. You are usually given a potential acquisition and asked to recommend for or against the deal and name a price. The interviewer wants a clear, well-reasoned recommendation, not just a complicated model.

How long is a corporate development case study?

Most on-site corporate development case studies last 30 to 60 minutes, after which you may present your findings to the team. Take-home versions give you anywhere from a few days up to a week. Plan your time so you finish with a recommendation rather than a half-built model.

How do you value a company in a corporate development case?

Value the target using a discounted cash flow analysis, comparable company multiples, and precedent transaction multiples. Triangulate these three methods into a price range, then layer in synergies to decide the most you would pay. In a short on-site case, keep the model simple and defend your assumptions.

Is a corporate development case the same as a consulting case interview?

No. A consulting case interview covers a wide range of business problems, while a corporate development case almost always centers on a specific deal and leans more heavily on valuation and financial modeling. Both reward the same structured thinking and clear communication, so case interview practice transfers well.

How much do corporate development analysts make?

According to Glassdoor data from February 2026, corporate development analysts in the United States earn an average of about $115,000 per year, with top earners reporting roughly $176,000. Pay varies widely by company size, industry, and location, and tends to be lower than investment banking or private equity.

How do you prepare for a corporate development case study interview?

Practice valuing real companies, review accretion and dilution and basic merger math, and study recent deals in the company's industry. Run timed mock cases where you reach a buy or pass recommendation and a price. Then prepare to defend your assumptions out loud, since you will often present to the team.
