1. 017What would your allocation be in today's market?Asset allocationHardtechnicalAmundiRates · London · 2018

   Say this

   Answer it as a portfolio, not a list of opinions. State the benchmark you are deviating from, give three or four tilts with a reason and a size for each, say what would make you wrong, and name the one risk that hurts every position at once.

   Then walk it

   1. Anchor first: 'against a 60/40 policy, I would run these deviations.' Without an anchor the answer is untestable and interviewers notice.
   2. Then the tilts, each with a mechanism. For example: neutral to modestly underweight developed equities on valuation with the earnings yield close to real bond yields, overweight duration where real yields are positive and inflation is converging to target, overweight investment grade credit over high yield because the spread per unit of leverage is better, and a small allocation to gold or trend following as the diversifier that does not depend on a correlation estimate.
   3. Size them. 'Plus 5 points duration, minus 3 equities, 3 in trend' is a portfolio. 'I like bonds' is a comment.
   4. Say the single dominant risk. In most current configurations it is that inflation re-accelerates, which hurts both legs of a 60/40 simultaneously, as 2022 showed. Name it and say what you hold against it, real assets or inflation-linked bonds.
   5. Then the falsifier and the horizon: what data would make you reverse, and when do you review. A view without an exit condition is a position you will hold too long.
   6. Close with honesty about the base rate: these are modest tilts because the evidence on tactical allocation is weak, so the policy mix is doing most of the work. That framing reads as professional rather than hesitant.

   Where candidates lose it

   Delivering a macro monologue with no benchmark, no sizes and no falsifier. The interviewer is testing whether you think in portfolios and whether you have actually looked at the current numbers. Know today's ten year yield, the index forward multiple and where credit spreads are, or the answer collapses on the first follow-up.

   Expect next

   • Where is the ten year yield right now?
   • What would make you reverse the duration call?
   • How would you express that view in instruments?

2. 060Why is the dollar so strong, and what does that do to a global portfolio?Currency and globalIntermediatetechnicalAmundiAsset Management · Milan · 2022

   Say this

   Three drivers, and you should name which one is dominant right now: a rate and growth differential in America's favour, safe-haven demand when risk appetite falls, and the dollar's structural role in funding and trade invoicing. The portfolio effect is that unhedged dollar assets flatter returns for a non-dollar investor and crush emerging market performance.

   Then walk it

   1. Driver one, real rate differentials. Capital flows to the higher real yield, so when the Fed is tighter than the ECB and the Bank of Japan, the dollar rises. Watch the two-year real yield gap as the cleanest single indicator.
   2. Driver two, the risk premium channel. The dollar is the reserve and funding currency, so in a stress event everyone needs dollars to service dollar liabilities and the currency rises exactly when risk assets fall. That is why it behaves as a hedge in a portfolio.
   3. Driver three, growth and terms of trade. Stronger relative US growth, plus energy independence during an energy shock, both support it. Europe in 2022 was importing expensive gas, which is a straightforward terms-of-trade hit to the euro.
   4. Portfolio effect one: for a euro or rupee-based investor, unhedged US equity returns get a currency tailwind, which flatters US allocations and disguises weak underlying performance. Strip the currency out before concluding that US equities beat everything.
   5. Portfolio effect two: a strong dollar is a tightening of global financial conditions. Emerging market sovereigns and corporates with dollar debt see their debt service rise in local terms, commodity importers suffer, and EM equity in dollar terms underperforms. So a dollar view is implicitly an EM allocation view.
   6. Then the mean-reversion caveat: purchasing power parity has almost no predictive power over one to three years but does over five to ten, so an extreme real effective exchange rate is a slow signal at best. I would treat it as a reason to hedge more of a new US allocation rather than as a trade in itself.

   Where candidates lose it

   Giving one reason, usually rate differentials, and no portfolio consequence. The question has two halves and the second is where the portfolio manager is being tested: the currency tailwind flattering US allocations, and dollar strength as a tightening of global conditions that hits emerging markets. Also know roughly where the dollar index and the rate differential are today.

   Expect next

   • So would you hedge your dollar exposure now?
   • What does dollar strength do to Indian equities and the rupee?
   • Does purchasing power parity help you at all?

3. 069How does Vanguard differ from BlackRock, PIMCO and UBS?Active versus passiveIntermediatefirst roundVanguardInvestments · Malvern · 2023

   Say this

   The ownership structure, and everything follows from it. Vanguard is owned by its own funds and therefore by its investors, so there is no external shareholder to earn a margin, which is why fees fall as assets grow. The others are shareholder-owned or bank-owned businesses with different strategic logics.

   Then walk it

   1. Vanguard: mutual ownership, at-cost pricing, dominant in low-cost index funds and increasingly in advice, with a large retail and defined contribution base. The strategy is scale plus cost leadership, and the stated purpose is to lower the cost of investing.
   2. BlackRock: listed, shareholder-owned, the largest manager globally, strong in ETFs through iShares but with a second engine that Vanguard does not have, Aladdin, which is a risk and portfolio technology business sold to other institutions. That is a software franchise inside an asset manager.
   3. PIMCO: fixed income specialist, owned by Allianz, built on active bond management, macro research and a total return heritage. Deep expertise in a narrow field rather than breadth, and the business model still depends on active fees.
   4. UBS: a global bank whose asset management sits alongside the largest private wealth franchise in the world. Distribution through advisers and access to wealthy clients is the core advantage, and post-Credit Suisse it is also a consolidation story.
   5. So the four occupy different points on one map: cost-led scale, technology-plus-scale, active specialist, and distribution-led. Fee pressure is compressing all of them, which is why every one of them is pushing into private markets and into technology or advice, where fees are more defensible.
   6. If I were asked which I would want to work for, I would answer it as alignment: the mutual structure means the investment case and the client case are the same document, and I find that easier to argue in front of a client than a business that has to grow margin.

   Where candidates lose it

   Comparing them on product ranges and assets under management. The distinguishing answer is ownership structure and the strategic logic it produces, and knowing that BlackRock's second business is technology rather than funds. If you are interviewing at Vanguard and cannot explain what mutual ownership means in practice, you have not done basic preparation.

   Expect next

   • What does mutual ownership mean for fees over time?
   • What is Aladdin and why does it matter?
   • Where does fee pressure end?

4. 071What challenges does a large asset manager face in the current macroeconomic environment?Active versus passiveIntermediatefirst roundVanguardAsset Management · Malvern · 2023

   Say this

   Fee compression against a cost base that keeps rising, the fact that cash now pays a real return and competes with every product, and the strategic problem that the industry's growth areas, private markets and technology, are not what most large managers were built to do.

   Then walk it

   1. Revenue: fees fall every year through both price cuts and mix shift into passive, so revenue per unit of assets declines even when markets rise. Since markets have carried the revenue line for a decade, a flat market exposes that immediately.
   2. Cost: technology, data, regulation and talent all cost more, so operating leverage runs the wrong way. That is why consolidation continues and why scale has become the defining variable.
   3. The rate environment changes product demand fundamentally. When cash yields 5 percent, the case for a 6 percent expected return multi-asset fund with volatility is much weaker, and money market funds absorb enormous flows. Bond funds also spent 2022 teaching clients that fixed income can lose 15 percent.
   4. Correlation is the deeper problem for multi-asset houses. The 60/40 proposition sold for forty years rested on bonds hedging equities, and in an inflation-shock regime they do not. So the product needs new diversifiers, which means alternatives, trend following and real assets.
   5. Structural: the flow of money into private markets and the blurring between traditional and alternative managers. Everyone is buying private credit and infrastructure capability, which is expensive, culturally difficult and arrives after the easy returns.
   6. And the specific challenge for an index-led house is different from the general one: your revenue is a fixed tiny percentage of assets, so you are enormously levered to market levels and to flows, and your growth has to come from adjacent services such as advice, cash management and retirement solutions rather than from raising fees. That framing is the one to use in an interview with a passive-led firm.

   Where candidates lose it

   Reciting macro headlines without connecting them to the manager's profit and loss. The four things to link are revenue per unit of assets, the cost base, what cash yields do to product demand, and the correlation breakdown that damaged the core multi-asset proposition. Tailor the last point to whether you are talking to a passive-led or active-led house.

   Expect next

   • What does 5 percent cash do to your product set?
   • Is 60/40 still a valid proposition?
   • How should a passive-led firm grow from here?

5. 078What are SIP flows doing to Indian equity valuations?India marketsIntermediatetechnicalIndian asset managementMutual funds

   Say this

   They have created a large, monthly, largely price-insensitive domestic bid that has structurally raised valuations, particularly in mid and small caps where the flow is enormous relative to free float. The open question is not whether it supports prices but how it behaves in the first genuine drawdown.

   Then walk it

   1. The mechanism: monthly systematic investment plans now run at well over 20,000 crore rupees a month, and that money has to be deployed roughly on arrival. Managers hold modest cash, so a fund receiving inflows is a forced buyer at whatever the market price is.
   2. Where it binds hardest is small and mid caps. A small cap fund receiving 500 crore a month in a universe where the median name trades a few crore a day has to buy price-insensitively, which is why small cap premiums to large caps reached historically extreme levels and why SEBI required stress testing and some AMCs restricted lump sum inflows.
   3. The valuation consequence is a mechanical one, not a story about earnings. Persistent inelastic demand against limited free float raises the price until either supply appears, which it has through record IPO and promoter and private equity selling, or demand slows.
   4. The stabilising feature is real, though. SIP investors have been much stickier than lump sum investors: flows kept rising through the 2020 crash and through 2022, which meaningfully reduced India's historical dependence on foreign flows and dampened drawdowns.
   5. The untested question is behaviour in a long sideways or falling market. SIP behaviour has been observed mostly in a rising market since 2014, with only short drawdowns. A three-year flat market with negative small cap returns would be the real test, and stoppage ratios are the metric to watch.
   6. For portfolio construction the implications are concrete: be sceptical of small cap valuations supported by flow rather than by earnings, treat liquidity and capacity as a first-order constraint in Indian small caps, and monitor monthly flow and stoppage data as a genuine input rather than a curiosity.

   Where candidates lose it

   Treating SIP flows purely as a bullish structural story. The interviewer wants the mechanical valuation effect, the small cap capacity problem, and honesty that stickiness has not yet been tested in a long drawdown. Quote an approximate monthly flow number; a candidate who cannot is not following the market they want to invest in.

   Expect next

   • What is the stoppage ratio and where is it now?
   • Why did SEBI ask for small cap stress tests?
   • How would you position if SIP flows halved?
6. 098Tell me what is happening in the markets right now.Career and fitIntermediatefirst roundInvescoAsset Management · Atlanta · 2023

   Say this

   Give it structure rather than a list of headlines: where the policy rate and the curve are, what equities are pricing in multiple and earnings terms, what credit spreads say, and then the one live debate you think matters most, with your own position on it.

   Then walk it

   1. Start with the anchor numbers, because credibility depends on them. The policy rate and where the market expects it in a year, the ten year yield, the index forward multiple, and investment grade and high yield spreads. Four numbers and you already sound like you work in this industry.
   2. Then the causal story in one or two sentences. Not 'stocks are up' but the mechanism: is this an earnings market or a multiple market, is the rally broad or concentrated in a handful of names, is it being funded by real money or by flows?
   3. Then the one debate. Pick the live disagreement, the pace of policy easing, whether AI capital spending earns a return, whether credit spreads compensate for the refinancing wall, and say where you come out and why.
   4. Then the position implication, which is what makes it an asset management answer rather than a news summary. 'If that is right, I would rather own duration than credit here, and I would fund it from equities.'
   5. Then the honest uncertainty: what data in the next month would move your view. That is what a market view sounds like from someone who has actually held one.
   6. And add the local dimension if you are interviewing in India: the RBI's stance, the level and forward multiple of the Nifty, FII versus DII flows, and the rupee. Domestic flows are the distinctive feature of the Indian market and mentioning them shows you follow it rather than reading about the S&P.

   Where candidates lose it

   Reciting headlines with no numbers and no view. Interviewers use this question purely to find out whether you follow markets daily, and the give-away is being unable to state the ten year yield or where the index is trading. Know four numbers cold, have one debate with a position, and finish with the portfolio implication.

   Expect next

   • Where is the ten year and what is priced for policy?
   • What would change your view?
   • How would you position for that?

7. 099Where did the S&P 500 close last night?Career and fitCorephone / first roundMSMorgan StanleyInvestments · Boca Raton · 2026

   Say this

   Know the number. There is no technique here. If you want to be paid to watch markets, you check the close, the direction, and the reason before you walk into an interview, and you add the same for the local index.

   Then walk it

   1. What to have ready every single day: the index level and the percentage move, the reason it moved, the ten year yield, the dollar, oil, and gold. In an Indian interview add the Nifty, the Sensex, the rupee and the previous day's FII and DII flow.
   2. Give the number, then add one sentence of interpretation so it is not just recall. 'Up about half a percent on a softer inflation print, and the move was in rate-sensitive sectors, which tells you it was a rates story rather than an earnings one.'
   3. Add the context that shows you have a longer frame: roughly where the index sits against its high, what it is up year to date, and what it is trading on in forward earnings terms. Level alone is trivia; level plus valuation is a view.
   4. If you genuinely do not know, say so once, quickly, and give the direction and the last level you did check. Do not guess a precise number, because being wrong by 300 points is far worse than admitting you have not looked since the open.
   5. Then use the recovery well: pivot to something you have been following closely and have a view on. It does not undo the miss, but it shows the habit exists even if today failed.
   6. The reason firms ask this is filtering, not knowledge. It costs two minutes a day, so not knowing is read as not being interested, and no amount of technical ability rescues that in a markets seat.

   Where candidates lose it

   Guessing. An interviewer who asks this knows the number, and a confident wrong answer is worse than 'I have not checked since the European close, it was around X and up a third of a percent'. The real failure is not having a daily habit; build one before you interview.

   Expect next

   • And the ten year?
   • Why did it move?
   • Where is the Nifty and what have FIIs been doing?

8. 100Tell me something going on in the world that has interested you, and what motivates you.Career and fitCorefirst roundBLBlackRockInvestment Research · New York · 2026

   Say this

   Pick something with an investment consequence you can trace, and take it three steps: the event, the mechanism, and what it means for an asset price. Then answer the motivation half honestly and briefly, because a long answer there sounds rehearsed.

   Then walk it

   1. Choose deliberately. Something you can carry for five minutes of follow-up, ideally connected to the firm's business: a policy shift, an industry restructuring, a technology with a measurable capital spending cycle, a change in market structure.
   2. Then the chain, which is the part being graded. Event, then mechanism, then price. 'Datacentre capital spending is running at X, it is being funded increasingly with debt rather than cash flow, which makes the return on that capital an investment grade credit question rather than only an equity story.'
   3. Have a number in it. One precise figure, cited, does more for your credibility than three paragraphs of narrative, and it proves you read the source rather than the summary.
   4. Then a view, with a falsifier. What would make you wrong, and what would you watch. Interest without a view reads as passive consumption of news.
   5. On motivation, be short and concrete. The honest version usually works: the feedback loop, being measured on judgement, the fact that the work compounds. Two sentences, one example from your own history, then stop.
   6. Avoid the two standard failures: picking a headline so large that you have nothing specific to add, and picking something politically charged where the interviewer's view is unknown and irrelevant to the job.

   Where candidates lose it

   Naming a big topic with no mechanism and no number. The interviewer is testing whether you translate news into investment consequence, which is the core of the job. On the motivation half, do not deliver a long personal narrative; brevity and one concrete example are more convincing than a story arc.

   Expect next

   • So how would you invest in that?
   • What would make you wrong?
   • What else have you been reading?
