1. 037What's the difference between an ETF and a mutual fund?Index funds and ETFsCorephone / first roundVanguardGeneralist · Malvern · 2026PIMCOCompliance · Los Angeles · 2024

   Say this

   An ETF is a mutual fund whose units trade on an exchange. You buy it from another investor at a market price during market hours; with a regular open-ended fund you transact with the AMC at end-of-day NAV. That one structural difference drives everything else — cost, tax, minimum size and how liquidity actually works.

   Then walk it

   1. Dealing: ETF units trade intraday at whatever the market pays, which can be above or below the underlying value. A mutual fund transacts at one NAV struck after the close, the same price for everybody that day.
   2. You need a demat account and a broker for an ETF. That is a real barrier in India and the main reason index funds, not ETFs, dominate retail passive money here while the reverse is true in the US.
   3. Creation and redemption happens only in large blocks with authorised participants, so the AMC never has to sell portfolio securities to fund a retail exit. In an open-ended fund, a redemption wave forces the manager to sell.
   4. Cost: ETFs are usually cheaper because there is no registrar servicing individual folios, but the investor pays brokerage, the bid-ask spread and any premium or discount to fair value. The headline TER understates the true cost of owning a thinly traded ETF.
   5. In the US, the in-kind redemption mechanism also gives ETFs a real capital gains advantage. In India that advantage does not exist, because the fund itself is a pass-through either way — worth saying, as it separates someone who understands the structures from someone repeating a US article.
   6. Which I would recommend depends entirely on the investor: an SIP investor should use an index fund, and an institution putting 50 crore to work in one day should use the ETF.

   Where candidates lose it

   Saying an ETF is passive and a mutual fund is active. That is a common conflation and it is wrong — the difference is the trading wrapper, not the strategy. There are active ETFs and passive index mutual funds. Lead with the exchange-traded structure.

   Expect next

   • Why do Indian retail investors use index funds rather than ETFs?
   • Explain the creation and redemption mechanism.
   • When would an ETF trade at a discount to its fair value?

2. 073How would you build a portfolio for a range of clients with very different needs and requirements?Portfolio construction and adviceIntermediatecase studyVanguardInvestment Research · Malvern · 2024

   Say this

   Start from the liability, not the product. For every client I need three things: when the money is needed, how much volatility they can actually tolerate as opposed to claim to tolerate, and what tax bracket and constraints they face. The asset allocation falls out of those, and fund selection is the last and least important step.

   Then walk it

   1. Horizon sets the equity share. Money needed inside three years does not belong in equity at all, whatever the client's risk appetite, because the worst three-year outcome is too bad. Beyond ten years, equity is the low-risk choice against inflation.
   2. Then capacity versus tolerance. Capacity is arithmetic — income stability, dependants, existing assets. Tolerance is behavioural. Where they conflict, size to tolerance, because a client who redeems in a drawdown converts a paper loss into a permanent one.
   3. Then build with as few products as possible. A large cap index fund, one flexi cap or mid cap, one short duration debt fund, and a liquid fund for near-term needs covers the large majority of clients. Complexity is the enemy of adherence.
   4. Differentiate at the edges, not the core. A 30-year-old with a stable salary and a 25-year horizon gets 75 to 85 percent equity with an SIP. A 60-year-old drawing income gets a bucketed structure with an SWP from the debt sleeve. A business owner with lumpy income gets a bigger liquid buffer.
   5. Then tax and jurisdiction. An Indian investor in the 30 percent bracket routes short-horizon money through arbitrage rather than debt funds. A US-taxable client cannot hold Indian mutual funds efficiently at all, and that constraint overrides every allocation view.
   6. And write down the rebalancing rule and the review date at the start. Most portfolios fail from drift and from ad hoc changes, not from bad initial selection — which is why I would rather have an average fund list with a written policy than a brilliant fund list without one.

   Where candidates lose it

   Answering with a fund list. The interviewer is testing whether you start from the client's liabilities and constraints. Also, distinguishing risk capacity from risk tolerance, and saying you would size to the lower of the two, is the line that separates an adviser from a salesperson.

   Expect next

   • What if the client's stated tolerance is much higher than their capacity?
   • How many funds should a portfolio hold?
   • How would you handle a client with a large concentrated stock position?

3. 084What challenges will this asset manager face in the current macroeconomic environment?Markets and industryHardsuperdayVanguardAsset Management · Malvern · 2023

   Say this

   Separate macro from structural, because they hurt differently. Macro affects this year's revenue through asset values and flows. The structural pressures — fee compression, the shift to passive and the cost of technology — do not reverse when markets recover, and they are the harder problem.

   Then walk it

   1. Start with the revenue model, because that is what makes the answer specific. An asset manager earns a percentage of assets. A 20 percent market fall cuts revenue by roughly 20 percent with a largely fixed cost base, so operating leverage works violently in both directions.
   2. Macro pressures: higher cash rates make money market funds and deposits competitive with long-term products, mix shifts to lower-fee products, and redemptions rise when investors need liquidity. Higher rates also hit the long-duration assets at the core of most balanced portfolios.
   3. Structural pressure one, fee compression. Passive at 3 to 10 basis points has reset what investors will pay for beta everywhere, and the average fee on the industry's assets falls every year even when no single fund cuts its price.
   4. Structural pressure two, distribution and regulation. In India that means TER slabs that tighten with scale, tighter commission rules and the direct-plan shift. Globally it means platform consolidation and fee transparency rules.
   5. Structural pressure three, cost. Technology, data, compliance and risk systems all scale, which means the answer for a sub-scale manager is consolidation — and that is why the industry keeps merging.
   6. Then say what you would do about it, because the question is really about commercial judgement: defend the core with scale and cost, differentiate where fees can still be earned, and grow the parts of the business that are not pure beta. And note the firm-specific angle — for a low-cost passive house the structural trend is a tailwind, not a threat.

   Where candidates lose it

   Listing macro risks — inflation, rates, geopolitics — without connecting them to the firm's revenue. The interviewer wants to know whether you understand that this is a business with fee income linked to assets. Not distinguishing cyclical from structural is the second failure, because the strategic answer differs entirely.

   Expect next

   • How does that flow through to their revenue?
   • Which of those is temporary and which is permanent?
   • What would you do about it if you ran the firm?

4. 087How does this firm differ from other asset managers — BlackRock, PIMCO, UBS?Markets and industryIntermediatefirst roundVanguardInvestments · Malvern · 2023

   Say this

   Differentiate on ownership, business model and where the assets actually are — not on adjectives. These four firms are genuinely different businesses: a client-owned low-cost index house, a listed indexing and technology platform, a fixed income specialist, and a bank-owned wealth manager with asset management attached.

   Then walk it

   1. Ownership is the sharpest axis and the one candidates miss. A mutual, client-owned structure means the economics of scale flow back to investors as lower fees rather than to shareholders, which explains the entire product strategy. A listed manager has to grow margin as well as assets.
   2. Business model next: is the firm selling beta at scale, selling a specialist capability, or selling advice and distribution with products attached? BlackRock's index and risk-technology platform, PIMCO's fixed income franchise and UBS's wealth-led model are three different answers to how you make money in this industry.
   3. Then asset mix, with rough numbers if you have them. A predominantly passive equity book, a predominantly fixed income book and a predominantly private-client book behave completely differently when rates move.
   4. Then culture and how it shows up in the work. A firm built on low-cost indexing runs a very different research function from one built on active credit, and the day-to-day job you are applying for differs accordingly. Say what that means for your role.
   5. Then be honest about the trade-offs rather than flattering them. A scale indexer gives you reach and discipline but less freedom to express a view. A specialist gives you depth in one asset class and more concentrated career risk. Naming that is more persuasive than praise.
   6. For an Indian version of this question, the same axes work: bank-sponsored fund houses like SBI and ICICI Prudential with captive distribution, standalone AMCs competing on performance and brand, and the new passive-first players competing on cost.

   Where candidates lose it

   Praising the firm's culture in generalities. Anyone can say a firm is investor-focused. This question rewards knowing the ownership structure, the asset mix and where the revenue comes from. Getting the basic business model wrong — calling a fixed income house a passive giant — ends the interview.

   Expect next

   • Which of those business models do you think wins over the next decade?
   • How does our ownership structure change what we do?
   • Who is our real competitor for the client's money?

5. 090Why this firm?Career and fitCoreevery roundVanguardCorporate Banking · Malvern · 2023

   Say this

   Three things, each of which must be true only of them: something about the business model or ownership, something about the specific desk or product you would join, and something you learned from a person rather than the website. Then one honest reason it suits you.

   Then walk it

   1. Layer one, the firm's actual model. Client-owned and structurally low cost, bank-sponsored with captive distribution, a fixed income specialist, a passive-first challenger — whatever it is, name it and say why that model appeals to you. This is where most candidates are interchangeable and you do not have to be.
   2. Layer two, the seat. Name the fund, the strategy, or the function, and say something specific about it: the category it competes in, how it is positioned, a product they launched recently. For an Indian AMC that might be their passive lineup, their debt franchise or their reach in smaller cities.
   3. Layer three, a person. 'I spoke to someone on your credit team and what struck me was how the analysts own the recommendation end to end.' One sentence of first-hand detail outweighs everything you could quote from the annual report.
   4. Then the fit, stated in terms of what you bring rather than what you want. Match a specific skill or experience to something the seat needs.
   5. Keep it under ninety seconds. This is a filter question, not a pitch, and the failure mode is length. Say three specific things and stop talking.
   6. One more thing: be ready for the inverse. If they ask which of their funds you would not buy, having an honest answer ready — respectfully framed — is the strongest signal you have actually looked at the product range.

   Where candidates lose it

   Reciting AUM, awards and founding year. That is available to everyone and signals nothing. The disqualifier is not knowing what the firm actually sells — candidates who cannot name one of the firm's funds in an interview for a fund house do not recover from it.

   Expect next

   • Which of our funds would you buy with your own money?
   • Who do you see as our main competitor?
   • What do you think we do worse than our competitors?
