ECM interview questions

1Why ECM and sector fit6 questions

Why do you want to work in ECM specifically?

The strongest answers name a specific mechanic or tension, not a general love of markets. ECM sits between coverage bankers, who own the client relationship, and sales and trading, who own the investor relationships, and its central skill is translating between the two: structuring a deal on the client side and pricing it against real, live investor demand on the market side. A good answer picks something concrete, the tension between pricing a deal high enough to raise real capital and low enough to leave room for the stock to perform afterward, or the way a convertible bond blends credit and equity pricing into one instrument, and connects that specific interest to wanting to do the actual translation work ECM does. Avoid generic enthusiasm for "the stock market," since that alone does not distinguish an ECM candidate from a sales and trading or equity research candidate, all of whom could say the same thing.

What is the difference between ECM and a coverage group like TMT or healthcare?

ECM is a product group, organized around a type of transaction, raising equity or issuing an equity-linked security, rather than an industry. It staffs across every sector, working with coverage bankers in groups like TMT or healthcare whenever one of their clients decides to raise equity or issue a convertible bond. A coverage banker owns the underlying client relationship across every kind of transaction that client might do; ECM is the technical specialist brought in specifically when that transaction is an equity issuance. Confusing the two, describing ECM purely as "advising companies" without mentioning pricing or investor demand, is a common mistake that signals a candidate has not fully separated the product-versus-coverage distinction that structures how most banks organize their banking division.

What's the biggest misconception people have about ECM?

A common misconception is that ECM is just "the IPO group." In reality, IPOs are one product among several, follow-ons, block trades, and convertible bonds all run through the same group, and a company that already went public two years ago is still very much an ECM client whenever it wants to raise more equity or issue a convert. A second misconception is that ECM work is glamorous and deal-heavy at every moment; in practice a large share of the job, especially before a deal is public, involves unglamorous maintenance: tracking which companies look like plausible issuance candidates, building pitch materials, and monitoring how recent deals have traded, work that looks a lot like the origination work in any other product group even though the eventual transaction type is different.

Why ECM over M&A?

Both groups execute transactions for coverage-originated clients, but the pricing mechanism and counterparty are completely different. ECM sells a security to a market of investors and prices against real-time demand read from an order book; M&A negotiates a single transaction price directly with one counterparty, a buyer or a seller. I find the market-judgment side of ECM, reading live investor sentiment and translating it into a price, more compelling than negotiating price and terms with a single party, and I want to build skill in that specific kind of real-time judgment rather than the deal-structuring and negotiation skill M&A centers on. Both are valuable and related skill sets, but they reward genuinely different instincts, and ECM's blend of structuring plus live market reading is the one that fits how I want to spend my time.

Why ECM over sales and trading?

Both reward market awareness, but I want to be closer to origination and structuring, building the case for why a specific deal makes sense and staying involved with the client relationship, rather than executing orders once a deal is already priced. Sales and trading is largely reactive to deals that already exist; ECM origination shapes which deals happen in the first place and how they're structured, which is the part of the job I find most interesting. I also like that ECM sits at a genuine intersection, enough modeling and structuring work to stay technically engaged, enough market-facing work to stay connected to live investor sentiment, rather than specializing fully in either the analytical or the purely market-facing side of the business.

What sub-product within ECM interests you most, and why?

This question tests whether a broader "why ECM" answer has real substance underneath it. A strong response names one product, IPOs, follow-ons, block trades, or convertibles, and explains a specific mechanic that draws you to it: for IPOs, perhaps the tension between clearing the deal and leaving room for the stock to perform; for convertibles, perhaps the challenge of pricing a single instrument as both a bond and an option at once; for block trades, perhaps the speed and principal risk involved in committing to buy a position before knowing for certain it can be resold. The goal is to show you have engaged with one part of the product landscape deeply enough to reason about it, not simply that you can list all four products from memory.

2The IPO process and mechanics6 questions

Walk me through the IPO process from start to finish.

It starts with an organizational meeting once a company has selected its underwriters, setting a working timeline with the full deal team, bankers, lawyers, and auditors. The largest chunk of time goes into due diligence and drafting the registration statement, the S-1, and once that's filed publicly the company enters a quiet period restricting promotional communication. The SEC reviews the filing and the company amends it until the SEC clears it. Once the deal team has a credible price range, the company files an updated S-1 with that range and starts the roadshow, meeting investors directly while the syndicate desk builds the order book. On the evening the roadshow ends, the deal team holds a pricing call and sets a final price. The next morning the stock opens for trading, and the syndicate desk shifts into stabilization mode using the greenshoe, while existing shareholders stay locked up for a period before they can sell.

What is an S-1, and what does it contain?

An S-1 is the registration statement a company files with the SEC to register securities for a public offering, most commonly associated with an IPO. It describes the company's business model, competitive position, financial statements, risk factors, use of proceeds, and the terms of the offering itself, including, once set, the price range. It is the core disclosure document investors rely on when deciding whether to participate in the deal, and it is also the document underwriters are legally exposed on if it contains a material misstatement or omission, which is why due diligence and careful drafting consume so much of the pre-roadshow timeline. The S-1 gets amended, sometimes multiple times, in response to SEC comments before being declared effective, and a final version, reflecting the actual offering terms, gets filed once the deal prices.

What is the quiet period, and why does it exist?

The quiet period is a stretch of time, generally running from shortly before a company files its registration statement through a period after the offering completes, during which securities law restricts what the company and its underwriters can say publicly about the business and the offering. It exists to prevent a company from conditioning the market with promotional statements made outside the carefully vetted, legally reviewed offering documents, ensuring that investors evaluate the deal based on the prospectus rather than informal hype. In practice this means companies preparing to go public are unusually cautious about press interviews, promotional announcements, and even some ordinary public communications in the months around a filing, and marketing the actual deal has to happen through the formal roadshow process rather than general public statements.

What is the difference between a firm commitment underwriting and a best-efforts offering?

In a firm commitment underwriting, the standard structure for almost all US IPOs, the underwriters agree to buy the entire offering from the company at the agreed price and resell it to investors, taking on the risk that the deal might not fully sell at that price. In a best-efforts offering, the underwriter only agrees to try its best to sell the securities on the company's behalf, without guaranteeing to buy any unsold portion itself, meaning the company bears the risk of an undersold deal directly. Firm commitment underwriting is possible because, by the time a deal actually reaches pricing, the order book has already been built and thoroughly vetted during the roadshow, so the practical risk to the underwriters is much smaller than it might first appear, even though the legal structure formally puts that risk on the bank's own balance sheet between pricing and settlement.

What happens during the SEC review process?

After a company files its initial S-1, the SEC staff reviews the document and typically responds with comments: questions about disclosure, requests for additional detail on the business or financials, or concerns about specific risk factors or legal language. The company and its lawyers respond to these comments, often filing one or more amended S-1s, continuing this back-and-forth until the SEC has no further comments and is prepared to declare the registration statement effective. This process can take anywhere from a few weeks to considerably longer depending on how complex the business is and how many rounds of comments arise, and it typically runs in parallel with other preparation, since the deal team does not simply wait idle while amendments are being negotiated.

What is a lockup agreement, and why does it matter?

A lockup agreement restricts existing shareholders, typically insiders, employees, and pre-IPO investors, from selling their shares for a set period after the offering, commonly 90 to 180 days. It matters because it keeps the newly public float, the shares actually available to trade, smaller in the deal's early life, which supports price stability by preventing a flood of insider selling right when the stock is most fragile and has the least trading history to absorb it. When the lockup expires, a large number of previously restricted shares can become sellable at once, an event the market often anticipates and prices in ahead of time, sometimes creating downward pressure on the stock even without any change in the company's underlying fundamentals.

3Pricing, bookbuilding, and allocation7 questions

How is pricing an IPO different from valuing a company?

Valuing a company is analytical: applying a methodology like comparable companies or a discounted cash flow to estimate what the business is intrinsically worth. Pricing an IPO layers a market exercise on top of that valuation, reading real-time demand from the order book built during the roadshow and setting a price that clears the deal while leaving room for the stock to perform once trading starts. The two are related but distinct: a valuation range anchors where the deal team starts, but the actual offer price depends on how investors respond during marketing, not just on the underlying analytical work, since a company that wants to raise capital again in the future needs this deal's investors to make money, not just the underwriters to collect a fee on this one.

Why do IPOs typically price at a discount to where they trade in the aftermarket?

Underwriters generally set the offer price low enough that new investors have a reasonable expectation of a positive first-day return, since those investors are taking on real risk buying a stock with no public trading history. Pricing exactly at the level the stock is expected to trade removes that cushion and risks a deal that trades down on its first day, damaging the company's and the underwriters' credibility for future capital raises. The size of that discount is a judgment call: too large and the company leaves obvious value on the table, too small and the deal risks breaking issue price, so the deal team calibrates it based on the strength and composition of the book built during the roadshow.

What is a greenshoe, and how does it work?

A greenshoe, or overallotment option, lets underwriters sell up to an additional 15% of shares beyond the base deal size at pricing, going short that extra amount against the company. If the stock trades up afterward, the underwriters exercise the option, buying those shares from the company at the original offer price to close out the short. If the stock trades down, the underwriters instead buy the shares back in the open market, which creates real buying pressure supporting the price exactly when it's most fragile. This stabilization effect is a byproduct of the underwriters closing their own short position, not a separate, discretionary favor to the company, which is an important nuance interviewers often check for.

Walk me through how a book gets built during a roadshow.

Once the roadshow begins, the syndicate desk opens an order book and collects indications of interest from institutional investors through each underwriter's sales force, typically specifying a share quantity and a price condition, whether the investor wants shares at any price in the range or only below a specific limit. The desk aggregates every order across the whole syndicate into a continuously updated book, tracking not just total demand but how the book would look at different possible price points, since some orders drop out at higher prices. What matters is composition as much as size: a book with strong participation from large, patient, long-only investors is a healthier foundation for pricing than one padded with shorter-term-oriented demand, even at the same headline oversubscription multiple.

How would you decide allocation on an oversubscribed deal?

I would weigh the tradeoff between building a stable shareholder base and maintaining broad market goodwill. Allocating heavily toward large, long-only investors who tend to hold positions for years supports price stability in the deal's early life, since they are less likely to sell quickly. But allocating too narrowly can frustrate other investors who placed real orders and got little or nothing, souring their willingness to participate in the company's next offering. In practice I'd aim for a blend: meaningful allocations to anchor and long-only demand to support stability, with reasonable allocations spread across other investors to maintain goodwill, informed by which accounts have a track record of holding versus quickly flipping recently priced deals.

What is a penalty bid?

A penalty bid lets the lead underwriter reclaim the selling concession, a portion of the underwriting fee, from a syndicate member whose client sells, or "flips," their allocated shares shortly after the deal prices. It exists specifically to discourage syndicate members from allocating shares to investors known for quickly flipping newly issued stock, since heavy early selling can pressure the stock down right when it is least able to absorb it. It is a targeted tool alongside the broader stabilization the greenshoe provides, aimed at the allocation decision itself rather than at supporting the price directly in the market.

What signals in the order book would make you recommend pricing at the top versus the bottom of the range?

A book that is many times oversubscribed, with strong participation from large, high-quality, long-only investors, and that remains well subscribed even at the top of the marketed range rather than only at the bottom, supports pricing at or above the top of the range. A book that only fills near the bottom of the range, or that requires unusually aggressive selling effort from the syndicate to fill even at the bottom, suggests investors see less value than the deal team expected, and would push me toward pricing at the low end or, in a weak enough case, considering whether the deal should be resized or postponed rather than priced into insufficient demand.

4Convertibles and equity-linked products5 questions

What is a convertible bond, and why would a company issue one?

A convertible bond pays regular coupon interest and returns principal at maturity like an ordinary bond, but gives the holder the option to convert it into a fixed number of shares at a set conversion price above where the stock trades at issuance. A company issues one to borrow at a lower coupon than straight debt would require, since investors accept less guaranteed return for the embedded equity upside, and to raise capital without immediately diluting shareholders at today's stock price the way straight equity would. It suits a company that believes its stock is currently undervalued but still wants cheaper financing than straight debt and is comfortable with eventual dilution if the stock performs well enough to justify conversion.

What are the two components of a convertible bond's value?

A convertible bond's value splits into a straight bond value, what the instrument would be worth based purely on its coupon, maturity, and the issuer's credit risk with no conversion feature at all, and the value of the embedded conversion option, the right to convert into equity, which behaves like a call option on the company's stock. The option's value depends heavily on the stock's volatility, since more volatility means a greater chance the stock rises well above the conversion price. Pricing a new convert means finding a combination of coupon, conversion premium, and maturity that fairly reflects both components together, which is why converts are typically priced with input from both ECM and DCM.

What is a conversion premium, and how does it affect pricing?

The conversion premium is how far above the current stock price the conversion price is set, expressed as a percentage. A higher premium means the stock has to rise further before conversion becomes attractive, making the embedded option less valuable to the investor, which all else equal requires a higher coupon to keep the overall package attractive. A lower premium makes the option more valuable to the investor but means the company gives up more effective upside before conversion protection kicks in, and typically supports a lower coupon in exchange. Structuring a convert means finding the combination the issuer and the market both find acceptable on this tradeoff.

Who buys convertible bonds, and why does that matter for how they're marketed?

A meaningful share of demand comes from convertible arbitrage funds, hedge funds that buy the bond and simultaneously short the issuer's stock, aiming to profit from the option's value and from volatility largely independent of the stock's direction. This is a different investor base than the one that participates in a straight equity roadshow, and it means marketing a convertible deal targets a different set of accounts, often running its own compressed process, than marketing a follow-on or IPO does, even though both eventually touch the same company's capital structure. Traditional fixed-income and some equity-oriented long-only investors participate too, particularly for well-known, high-quality issuers.

What is a call spread overlay?

A call spread overlay is a separate, privately negotiated derivatives transaction some issuers layer on top of a convertible bond to push the effective conversion price even higher than the bond's stated terms alone would provide. The company simultaneously buys a call option at the bond's stated conversion price and sells a call option at a higher price, using the net cost, typically funded from a portion of the bond's proceeds, to raise the level at which real dilution begins. The result behaves, from the company's perspective, like a convertible bond with a meaningfully higher conversion premium than what is actually printed on the instrument, at the cost of paying separately for the overlay.

5Follow-ons, blocks, and other structures5 questions

What is the difference between a marketed follow-on and an overnight block trade?

A marketed follow-on runs a compressed version of the IPO process, a short roadshow, typically one to three days, and a book built the same way an IPO's is, just faster since the deal prices against a real, existing trading price rather than a range built from scratch. An overnight block trade skips the roadshow almost entirely: the underwriting bank canvasses institutional investors overnight and prices the deal before the market opens the next morning, typically at a wider discount reflecting the compressed timeline and reduced certainty. The choice between them depends on the seller's priorities: a company raising planned primary capital usually has time for a marketed process, while an existing large holder wanting speed and certainty, often a sponsor exiting a position, more often chooses the faster, wider-discount overnight route.

What is a shelf registration, and why does it matter?

A shelf registration is a filing a public company puts in place well before it has a specific deal in mind, registering a pool of securities it might sell over the following several years. With an effective shelf already on file, a company can launch an actual offering off of it in a matter of days rather than needing to draft and clear an entirely new registration statement each time, which is what makes the compressed timeline of a marketed follow-on, or an overnight block trade, mechanically possible. It matters in interviews because it explains why post-IPO equity deals can move so much faster than the IPO process itself, which has to build its registration statement from nothing.

What is the difference between a primary and a secondary offering?

A primary offering involves the company issuing brand-new shares, receiving the proceeds directly and diluting existing shareholders as a result. A secondary offering involves an existing shareholder, often a founder, early investor, or private equity sponsor, selling shares they already own, with proceeds going to that seller rather than the company, and no new dilution to other shareholders since no new shares are created. Many real offerings blend both in the same deal, a company selling new primary shares to fund its business while an early investor simultaneously sells down part of an existing stake, and interviewers sometimes ask candidates to explain why a board would agree to include a secondary component, usually a negotiated accommodation letting early backers begin realizing a return without waiting for a separate transaction later.

How does a direct listing differ from a traditional IPO?

A direct listing has no underwritten offering of new shares: existing shares simply become tradable on the exchange, with no bank buying and reselling anything, and the opening price is discovered live through a special opening auction rather than set in advance through a book built the night before. There is typically no formal multi-day roadshow, though the company may still hold investor presentations, and there is no greenshoe or other underwriter-provided stabilization tool once trading starts. It tends to suit an already well-known, well-capitalized company mainly seeking liquidity for existing holders rather than a large, certain capital raise, since a direct listing without a primary component raises no new money for the company at all.

What is a SPAC, and how does a de-SPAC merger work?

A special purpose acquisition company is a shell company with no operating business that completes its own IPO, raising cash held in trust with the purpose of acquiring a private operating company within a set time limit. Once the SPAC's sponsors identify a target, the two sides negotiate a merger, called a de-SPAC transaction, in which the private company effectively becomes public by merging into the already-listed shell rather than filing its own IPO registration. This merger is negotiated more like an M&A transaction, price and terms agreed directly between the two sides, than like a marketed securities offering, and it is often paired with a separate PIPE financing to fill any gap left by SPAC investors who choose to redeem their shares for cash instead of remaining invested through the merger.

6Market judgment and deal timing5 questions

Why do ECM deals cluster into "windows"?

Equity issuance is voluntary, so companies wait for conditions when a new deal is likely to be well received, low volatility and a recent track record of other new deals trading well rather than breaking. This creates a self-reinforcing pattern: a handful of well-received deals encourages more companies to launch, keeping the window open, while a stretch of poorly performing new issues makes investors cautious about the next one, closing the window quickly even without any change in the broader economy. It's a structural, repeating pattern describing investor sentiment specifically toward new issuance, distinct from sentiment about the stock market more broadly, and it exists in any market environment rather than being tied to any particular period.

What would make you advise a client to postpone a planned IPO?

I would look for signals that the market's current appetite for new issuance specifically, not just the broader stock market, has deteriorated: a stretch of recent deals trading down hard after pricing, unusually elevated volatility that would make investors reluctant to commit to an unproven stock, or a crowded forward calendar of similar companies competing for the same pool of investor capital in the same window. I would also weigh company-specific readiness, whether the S-1 and financials are genuinely finalized, separately from market timing, since a company can be operationally ready and still be better served by waiting a few weeks for conditions to improve, or, in the other direction, be advised to move faster if a favorable window looks likely to close.

If a company's stock has just had a strong quarter, would you recommend it raise equity now? Why or why not?

A strong quarter is a real point in favor of raising equity soon, since a higher stock price means less dilution for the same dollar amount raised, and strong recent performance tends to support investor demand in a follow-on roadshow. But I would still check a few things before recommending timing: whether the company is inside an earnings-related blackout period that would need to lift first, whether the broader market's appetite for new issuance is currently receptive rather than just this one company's own results looking good, and whether the company has a genuine, articulable use of proceeds, since a raise with no clear purpose can read poorly to investors even after a strong quarter. Good company-specific news is necessary but not sufficient on its own.

How would you advise a company deciding between debt and equity to fund an acquisition?

I'd start with how much existing leverage the company already carries, since a company near its comfortable debt capacity has less room to add more without raising its cost of debt or worrying its lenders. Then I'd look at how confident the projections behind the acquisition are: a highly stable, well-underwritten cash flow forecast favors debt, since it's cheaper capital and doesn't dilute shareholders, while a more uncertain forecast favors equity, since equity carries no fixed repayment obligation that could strain the company if the deal disappoints. I would also factor in the current market window for each option, since debt and equity markets do not always offer equally attractive terms at the same moment, and a convertible bond is sometimes the right answer specifically because it splits the difference between the two.

Why might a company's board choose a follow-on over a convertible bond, or vice versa, to raise the same amount of capital?

A follow-on is the more straightforward choice when the board is comfortable with immediate dilution at today's stock price and wants the simplicity of a single, all-equity instrument with no ongoing coupon obligation. A convertible bond makes more sense when the board believes the stock is currently undervalued, since a convert avoids locking in dilution at what management sees as a discounted price, and instead the company pays a lower coupon in the near term with dilution deferred to a higher effective price, and only if the stock performs well enough to justify conversion. The tradeoff is complexity and an ongoing fixed coupon obligation on the convert side versus immediate, simpler dilution on the follow-on side, and the right answer depends on management's own view of the stock's current value and the company's comfort carrying a coupon obligation until conversion or maturity.
