What is goodwill and how is it created in an acquisition?

Goodwill is the excess of the purchase price over the fair value of the target's identifiable net assets, created at deal close in purchase accounting. It represents intangible value you can't separately list — brand, workforce, expected synergies — and under US GAAP it isn't amortized, just tested annually for impairment.

What is a typical sell-side M&A process?

A sell-side M&A process involves preparation (teaser, CIM, valuation), a first round (teasers, NDAs, IOIs), a second round (data room, management presentations, LOIs), negotiation and signing of a definitive agreement, and closing after regulatory approvals.

What are the pros and cons of selling to financial sponsors vs. strategic buyers?

Strategic buyers can usually pay more because synergies make the target worth more in their hands, but they bring antitrust risk, integration, and management turnover. Sponsors are more price-disciplined but offer speed, regulatory simplicity, and continuity for the team and the business.

What happens if you write up assets for book purposes but not for cash tax purposes?

A deferred tax liability is created equal to the difference between the higher book basis and the lower tax basis multiplied by the tax rate, since future tax deductions will be smaller than book depreciation.

Sponsor vs. LP: what's the difference?

The sponsor — the general partner, or GP — is the private equity firm that raises and manages the fund and makes the investment decisions. Limited partners supply almost all of the capital, stay passive, and receive the bulk of the profits after the GP's fees and profit share.

What is the goal of an LBO?

The goal is to earn a high return on the sponsor's equity — typically a 20 to 25 percent IRR and a 2 to 3x multiple on invested capital over about five years — by funding the purchase mostly with debt and using the company's own cash flows to repay it.

Walk me through an LBO conceptually.

A PE firm acquires a company using mostly debt, uses the company's free cash flow to pay down that debt over ~5 years, then exits — generating equity returns through EBITDA growth, debt paydown, and multiple expansion.

What makes a good LBO candidate?

A good LBO candidate has stable and predictable cash flows supporting high leverage, strong free cash flow conversion for debt paydown, defensible market position, opportunities for EBITDA growth and margin expansion, low capex needs, and a clear exit path.

How do you determine how much debt to use in an LBO?

Debt is sized as a multiple of EBITDA — typically around 4 to 6 times total leverage, set by what lenders will provide — then checked against a coverage cushion: EBITDA should cover interest expense by roughly 2x or better, even in a downside case.

How do we determine capital structure between loans and bonds?

Fill the structure from the cheapest, most senior layer down: max out secured bank loans up to the secured leverage cap — roughly 3.5 to 4x EBITDA — then fund the remaining leverage with bonds. The finer split turns on prepayment flexibility, fixed versus floating rate, maturity, and how much ongoing lender restriction the company can live with.

How can a PE firm increase its return in an LBO? List 5 ways.

A PE firm can increase LBO returns by: (1) growing revenue, (2) expanding margins, (3) achieving multiple expansion at exit, (4) paying down debt during the hold period, and (5) increasing leverage at entry to reduce the initial equity check.

Paper LBO: you buy a company at 8x EBITDA using 5x of debt, EBITDA stays flat, and you exit at 8x in year five having paid down half the debt. What's your return?

Roughly a 1.8x MOIC and about a 13 percent IRR. Entry equity is 3 turns of EBITDA (8x price less 5x debt); exit equity is 8x EV minus the remaining 2.5x of debt, or 5.5 turns — and 5.5 over 3 is about 1.8x, which over five years is roughly a 13 percent IRR.

Advanced Investment Banking Interview Questions

Q: What are advanced investment banking interview questions?

Advanced IB interview questions test LBO returns, accretion/dilution, merger math, synergy value sharing, terminal value edge cases, sector-specific valuation, and judgment under follow-up pressure.

Q: How do you prepare for LBO intuition questions?

Practice explaining the equity bridge: entry equity, EBITDA growth, debt paydown, exit enterprise value, exit debt, exit equity, MOIC, and IRR. Then drill the direction of each driver until you can answer under 90 seconds.

Q: Are advanced IB questions only asked in Superdays?

No. Advanced questions are more common in Superdays and final rounds, but strong first-round interviewers can ask LBO, accretion/dilution, or DCF sensitivity follow-ups if a candidate handles the basics well.

Q: How many advanced IB questions should I practice before interviews?

Practice enough to cover the main advanced buckets: LBO returns, merger math, synergies, terminal value, and sector-specific valuation. For most candidates, that means at least 50 advanced questions after the beginner and intermediate base is stable.

Q: What should I do if I miss advanced technical questions?

Classify the miss. If it was a formula miss, drill the mechanic. If it was a direction miss, rebuild the intuition. If it was a pressure miss, practice saying the first clean 30-second version out loud before adding detail.

Q: What is the hardest LBO question banks ask in IB interviews?

The hardest standard LBO question is the on-the-fly paper LBO with synergies, where the interviewer asks for IRR given entry multiple, leverage, EBITDA growth, debt paydown, and a synergy capture assumption, all without a calculator. The trap is forgetting to net synergies through the equity bridge or anchoring on MOIC instead of IRR.

Q: How do I prepare for Superday IB technical follow-ups?

Superday follow-ups are usually variants of the same LBO and DCF questions you have already seen, with one assumption flipped or the answer pushed back on. Practice giving a 30-second first answer, then defending or revising it when the interviewer challenges the direction. Run mock pressure rounds where a friend pushes back on every answer with - are you sure - or - what if the opposite were true.

A practical article-style question list for candidates preparing for Superdays, later rounds, and pressure follow-ups.

What this level tests

LBO returns and sponsor math
Debt paydown, multiple expansion, and EBITDA growth
Synergy value sharing and strategic buyer logic
Biotech and finite-life asset valuation
Terminal value sensitivity and edge cases

Past this point, interviewers stop testing knowledge and start testing pressure. The questions are LBO mechanics, sponsor logic, terminal value edge cases - content you have seen - but the bar is whether you defend the assumption set when they push back.

How to know you are ready

You can frame the first answer in under 90 seconds.
You can defend the assumption set when the interviewer pushes back.
You can handle paper LBO, synergy, and terminal value changes without a calculator.
You can separate formula misses from judgment misses after each rep.

Advanced vs other question levels

Level	Example prompts	Ready when
Beginner	What does an investment bank do? What is enterprise value? Walk me through a DCF.	You can explain the concept cleanly before the first follow-up.
Intermediate	What happens if taxes fall in a DCF? How do AP days affect valuation?	You can connect formulas to valuation direction and name the trap.
Advanced	Calculate the LBO IRR. Why would a buyer not pay away all synergy value?	You can answer under pressure and defend the assumption set.
