Mergers & Acquisitions (M&A) Basics for Interviews
After Working Capital Management Explained, the next interview question is how companies use capital strategically beyond day-to-day operations. Mergers and acquisitions, or M&A, involves combining or acquiring companies to create strategic, operational, or financial value. It is a core investment banking competency and frequently discussed in corporate finance interviews.
- M&A involves combining or acquiring companies to create strategic, operational, or financial value.
- Common M&A types include horizontal merger, vertical merger, conglomerate, acquisition, merger of equals, hostile takeover, and LBO.
- Synergies are typically discussed as revenue synergies, cost synergies, and financial synergies.
- Revenue synergies are often overestimated by 50-100%; cost synergies are more reliable and typically realized 70-80%.
- In investment banking interviews, "Is a deal accretive or dilutive?" means whether the acquiring company's EPS increases or decreases post-acquisition.
- A Paper LBO is a quick back-of-envelope private equity interview exercise to estimate equity IRR in 2 minutes.
Big Picture: What M&A Tries to Create
M&A is used to create strategic, operational, or financial value. Interview answers usually start with the deal type, then move to synergy rationale, accretion or dilution, and, in private equity contexts, the paper LBO mental model.

Paper LBO - Framework Flow
A Paper LBO, or Leveraged Buyout on paper/mental model, is a quick back-of-envelope private equity interview exercise: given entry price, leverage, operating assumptions, and exit, estimate the equity IRR in 2 minutes.
Accretion/Dilution Interview Checks
In investment banking interviews, "Is a deal accretive or dilutive?" means: does the acquiring company's EPS increase, which is accretion, or decrease, which is dilution, post-acquisition?
Synergies - Revenue vs Cost
Synergies are the value creation logic behind a deal. They are usually grouped into revenue synergies, cost synergies, and financial synergies, each with a different quantification approach and reality check.
Notable Indian M&A Deals
Named transactions make M&A answers stronger because they connect deal type and synergy logic to real outcomes. These deals show how strategic rationale, integration, market disruption, and financing context can change the post-merger result.

Accretion/Dilution Analysis
Accretion/dilution is an interview insight because it links deal financing and operating performance to shareholder impact. A deal can be NPV-positive but EPS-dilutive in early years - both metrics matter.
In investment banking interviews, "Is a deal accretive or dilutive?" means: does the acquiring company's EPS increase (accretion) or decrease (dilution) post-acquisition?
Paper LBO Worked Example
Every private equity analyst interview includes this. The key metric is: Can you achieve 20%+ IRR? Typical private equity hold is 4-6 years and entry multiple is 6-10× EBITDA.
IRR Approximation Rules
Memorize these for paper LBO: 2× in 5 years ≈ 15% IRR; 3× in 5 years ≈ 25% IRR; 4× in 5 years ≈ 32% IRR; 5× in 5 years ≈ 38% IRR.
For a shorter hold: 2× in 3 years ≈ 26% IRR; 3× in 3 years ≈ 44% IRR.
Key LBO Value Creation Levers
- Revenue/EBITDA growth - most sustainable
- Multiple expansion - entering cheap, exiting at higher valuation
- Debt paydown - reduces EV required at exit to return equity
- Dividend recapitalizations - PE extracts cash before exit (controversial)
In India, LBOs are rare due to restrictions on pledging target's assets for acquisition debt, but PE buyouts (Warburg Pincus, KKR, Blackstone) are increasingly common in large transactions.
Structuring a Mergers & Acquisitions (M&A) Basics Interview Answer
"Is a deal accretive or dilutive?"
The strongest answers do not just say "synergies"; they separate revenue synergies from cost synergies and state that revenue synergies are often overestimated by 50-100%, while cost synergies are more reliable.
The most frequent error is treating accretion as the same thing as deal quality. A deal can be NPV-positive but EPS-dilutive in early years - both metrics matter, so explain the drivers instead of giving a one-word answer.
Conclusion
M&A basics are interview-ready when you can connect deal type, synergy logic, accretion/dilution, real Indian transactions, and the paper LBO framework. The final takeaway: always move from strategic rationale to quantification and then to execution reality.
