1. 006What areas of competitive advantage does this company have? Does it have barriers to entry, and can it sustain its revenue growth?Company analysisIntermediatecase studyMorningstarEquity Research · Chicago · 2023

   Say this

   Test the moat against the numbers rather than asserting it. A real competitive advantage shows up as returns on invested capital above the cost of capital, sustained for years, with stable or rising market share.

   Then walk it

   1. Name the source, and be specific. Intangibles like brand and patents, switching costs, network effects, cost advantage from scale or process, and efficient scale in a market too small for two players. Those five cover almost everything.
   2. Then prove it with evidence: ROIC consistently above WACC, gross margin stable through a downturn, pricing taken above inflation without volume loss, and customer retention.
   3. Then test durability directly. Ask what a well-funded competitor would have to do to take a customer, and how long it would take. If the answer is 'offer a lower price', there is no moat.
   4. On sustaining growth, separate the sources: price, volume, mix, new products, new geographies, and acquisitions. Growth from price and mix is high quality; growth from acquisitions is bought and should be valued differently.
   5. Then the honest test for a research note: is the moat widening, stable or narrowing? Morningstar's own framework is built on exactly that trend judgement, and it drives the fair value estimate far more than this year's earnings.

   Where candidates lose it

   Listing Porter's five forces as a memorised frame with no company-specific evidence. The grader wants the link from the qualitative claim to a number in the financials. No ROIC, no moat.

   Expect next

   • Is the moat widening or narrowing?
   • What return on capital does it earn against its cost of capital?
   • Would you rather own a low quality business at a great price or a high quality one at an okay price?

2. 008What is your investment philosophy, and what experiences led you to it?Investment philosophyIntermediatesuperdayFTFranklin TempletonEquity Research · San Mateo · 2024MorningstarEquity Research · Chicago · 2023

   Say this

   State a philosophy narrow enough to be falsifiable, then tie it to a specific experience, ideally one where you lost money and learned something. Vague philosophies signal you have not actually invested.

   Then walk it

   1. Pick a lane and say it plainly. Quality compounders at reasonable prices. Cyclicals at the point of maximum pessimism. Special situations. Underfollowed small caps. Any of these is fine; 'I look for undervalued companies with good management' is not, because nobody looks for the opposite.
   2. Then the formative experience, and make it concrete. A position you held, what you believed, what happened, what you changed.
   3. The losses teach better than the wins. Something like: I bought a cheap retailer on a low multiple and learned that a declining business gets cheaper faster than you can be right. That is why I now insist on returns on capital above the cost of capital.
   4. Then connect it to the seat. If they run concentrated long-only research, a philosophy built on fundamental durability fits. If it is a multi-manager platform, a philosophy about catalysts and risk control fits better.
   5. Keep the personal investing detail specific but modest. Interviewers want evidence you have skin in the game and a process, not a performance claim.

   Where candidates lose it

   A philosophy so broad it excludes nothing. Also, claiming a style that contradicts the firm you are sitting in. Read what they actually run before you answer.

   Expect next

   • What got you interested in investing, and what has changed since then?
   • What would you have done differently if you could go back to when you started?
   • Tell me about a position you lost money on.

3. 014What is an industry you have been following, and why?Sector knowledgeCorephone / first roundFidelity InvestmentsEquity Research · Boston · 2025HSBCEquity Research · New York · 2026MorningstarEquity Research · Chicago · 2023

   Say this

   Pick a sector you can discuss for ten minutes with numbers, name the structural change happening in it, and finish with the company you would own and why. Depth in one sector beats shallow coverage of five.

   Then walk it

   1. Choose deliberately: something with a live debate, where you can take a side. A sector where nothing is happening gives you nothing to say.
   2. Open with the structure: how many players, who has share, what the margin profile looks like, what drives demand.
   3. Then the change you are watching. A regulatory shift, a technology substitution, a capacity cycle, a demand inflection. This is the part that shows you think rather than read.
   4. Then the disagreement: what does the market believe about this that you think is wrong?
   5. Then land on a name. 'So within that, I would own X because it has the lowest cost position and the market is treating it as a commodity producer.' Always end with an actionable conclusion.
   6. Know four or five numbers for the sector: growth rate, typical margin, typical multiple, and the key operating metric. Being unable to answer 'what does it trade at' after claiming to follow it is fatal.

   Where candidates lose it

   Naming a fashionable sector you have only read headlines about. The follow-up is always a specific number, and if you cannot give it the whole answer collapses. Prepare one sector to genuine depth.

   Expect next

   • What does it trade at?
   • Which company in it would you own?
   • Compare the sectors you have covered and tell me which has the best prospects.

4. 016Walk me through a DCF, and tell me when it is the wrong tool for a research analyst.ValuationIntermediatetechnicalJefferiesEquity Research · New York · 2026MorningstarEquity Research · Chicago · 2023

   Say this

   Forecast unlevered free cash flow, discount at WACC, add a terminal value, then bridge to equity value per share. It is the wrong tool when the terminal value dominates so completely that the answer is just your assumption restated.

   Then walk it

   1. The mechanics are the same as on the banking side: EBIT taxed, plus D&A, less CapEx, less working capital change, discounted at WACC, plus terminal value, less net debt, divided by diluted shares.
   2. Where research differs is the use. A sell-side target price is usually set on a multiple, with the DCF as a cross-check and a way to demonstrate what the market is implying.
   3. The most valuable version is the reverse DCF: hold the current price constant and solve for the growth and margin the market must be assuming. That turns valuation into a testable statement about expectations.
   4. It is the wrong tool for banks and insurers, where you use a dividend discount or residual income model because interest is revenue and free cash flow is not meaningful.
   5. It is also weak for early-stage or deeply cyclical companies, where near-term cash flows are negative or unrepresentative and 90 percent of the value sits in the terminal assumption.
   6. So the honest framing: a DCF is most useful not for the number it produces but for making explicit what you have to believe.

   Where candidates lose it

   Delivering the banking answer verbatim. On the research side the expected addition is the reverse DCF and the awareness that DCFs are rarely the primary target-setting method. Say both.

   Expect next

   • How would you value a bank then?
   • What does the reverse DCF tell you about this stock?
   • What discount rate do you use and why?

5. 019How do you assess earnings quality?AccountingHardtechnicalMoody'sCorporate Finance · New York · 2018MorningstarEquity Research · Chicago · 2023

   Say this

   Compare earnings to cash. If net income is consistently above cash from operations, something is being recognised that has not been collected. Then check the accruals, the adjustments and the one-offs.

   Then walk it

   1. The headline test: cash conversion. Cash from operations divided by net income, tracked over several years. Persistent divergence is the single best red flag available from published accounts.
   2. Then working capital. Receivable days rising faster than revenue means revenue is being pushed to customers or collection is deteriorating. Inventory days rising means a write-down is coming.
   3. Then the adjustments. Compare GAAP to the company's adjusted figures and see what is being excluded. Restructuring charges taken every year for five years are not one-off, they are operating costs in disguise.
   4. Then capitalisation choices: capitalised development costs, capitalised interest, and the depreciation life. Extending useful lives flatters earnings with no economic change.
   5. Then the tax rate and the below-the-line items, since a sudden drop in the effective tax rate can manufacture an EPS beat.
   6. For a note, the useful summary is a bridge from reported earnings to what I think the sustainable earnings power is, with each adjustment listed. That bridge is often the most valuable page in a research report.

   Where candidates lose it

   Listing ratios without the organising idea. The organising idea is that accounting earnings involve judgement and cash does not, so every test is a version of comparing the two. Say that first.

   Expect next

   • What is the single best red flag?
   • How do you treat stock-based compensation?
   • Walk me through a company you thought had poor earnings quality.

6. 023What got you interested in investing, and what has changed since then?Career and fitIntermediatefirst roundMorningstarEquity Research · Chicago · 2023BLBlackRockInvestment Research · New York · 2026

   Say this

   The 'what has changed' half is the real question. It is asking whether you have learned anything, so the answer should describe a specific belief you held early and abandoned with evidence.

   Then walk it

   1. The origin should be concrete and modest. A first purchase, a company you knew through family, a competition, a book that made you look at an annual report.
   2. Then the evolution, which is where the substance is. 'I started out buying cheap stocks on low P/E and learned that cheap usually means something is broken' is a real answer.
   3. Or: 'I used to think a good product meant a good investment, and I learned that a great company at the wrong price is a bad investment.'
   4. Support it with the specific position that taught you, including the loss. Losses are more persuasive than wins because they are harder to fake.
   5. Close with the principle you now apply and how it shows up in your process. That converts a personal story into evidence of a method.

   Where candidates lose it

   Telling the origin story and skipping the evolution. Also the stock answer of 'I bought Apple at 15 and it went up'. Luck is not a philosophy; what you changed your mind about is.

   Expect next

   • What would you have done differently if you could go back to when you started?
   • What is your investment philosophy?
   • Tell me about a position you got wrong.

7. 030What would you have done differently if you could go back to when you started investing?Career and fitIntermediatefirst roundMorningstarEquity Research · Chicago · 2023

   Say this

   Name one specific mistake and the process change it produced. The answer should be a lesson about method, not about a stock you wish you had bought.

   Then walk it

   1. Good answers are about process: position sizing, selling too early, anchoring on purchase price, not writing the thesis down, trading on narrative rather than numbers.
   2. Make it concrete: 'I held a position through three quarters of deteriorating gross margin because I had decided I liked the company. Now I write down in advance what would falsify the thesis, and I check it every quarter.'
   3. The best version includes a behavioural insight about yourself. Knowing your own failure mode is what separates people who improve from people who repeat.
   4. Avoid 'I wish I had started earlier' and 'I wish I had bought more of the winner'. Neither is a lesson and both are things everyone says.
   5. Close with the current habit it produced, so the change is evidenced rather than claimed.

   Where candidates lose it

   Answering with a missed opportunity. That is regret, not learning, and it implies your main reflection is that you should have taken more risk. The expected answer is a process improvement born from a loss.

   Expect next

   • How do you avoid that now?
   • Tell me about a time you were wrong and changed your mind.
   • How do you decide when to sell?

8. 051How do you assess management quality?Company analysisHardtechnicalMorningstarEquity Research · Chicago · 2023

   Say this

   By their record on capital allocation, not by how impressive they are in a meeting. Look at what they bought, what they returned, what they promised and what they delivered.

   Then walk it

   1. Capital allocation first: the returns on the acquisitions they made, whether buybacks were executed at low or high valuations, and whether reinvestment earned above the cost of capital.
   2. Promises versus delivery: pull guidance from three and five years ago and compare it to what happened. Chronic over-promising is the most reliable negative signal available.
   3. Incentive structure: what are they actually paid on? EPS targets encourage buybacks and acquisitions regardless of value; ROIC or total shareholder return targets align better. Read the remuneration section, because it predicts behaviour.
   4. Insider ownership and trading: meaningful personal ownership relative to their salary matters far more than the raw percentage.
   5. Communication quality: do they disclose the metrics that would reveal a problem, or only the flattering ones? Did the definition of the adjusted metric change when it stopped working? Changing the goalposts is a red flag.
   6. And behaviour in the bad period. Anyone looks good in an upcycle. How they behaved in the last downturn, whether they cut the right things and whether they were honest about it, is the real test.

   Where candidates lose it

   Relying on impressions from management meetings. Good management teams are selected for being persuasive, so charisma is an unreliable signal. The evidence is in the capital allocation record and the remuneration policy.

   Expect next

   • What is the best evidence of poor capital allocation?
   • How do incentives change behaviour?
   • What would you ask a CEO in a one-on-one?

9. 087Tell me about a time you were wrong about a stock.Career and fitIntermediatesuperdayMorningstarEquity Research · Chicago · 2023Point72Investment Research · New York · 2026

   Say this

   Give a real position, state the thesis you held, say what actually happened, and identify the specific analytical error rather than blaming the market. Then the process change it caused.

   Then walk it

   1. State the original thesis in one sentence, exactly as you held it at the time. Reconstructing it charitably in hindsight is obvious and undermines the whole answer.
   2. Then what happened and what you missed. Be specific about the type of error: you overestimated pricing power, you trusted a management forecast, you ignored the balance sheet, you anchored on the purchase price.
   3. Distinguish a bad decision from a bad outcome. Some losses come from good process and bad luck; others from process failure. Showing you can tell them apart is the highest-value part of the answer.
   4. Say what you did when the evidence turned. Did you cut, add, or freeze? Freezing is the honest answer for most people and admitting it is fine if you explain what you now do instead.
   5. Then the process change, concretely. 'I now write the falsifier down when I initiate and check it every quarter' is better than 'I learned to be more careful'.
   6. Avoid stories where you were secretly right and the market was wrong. That is not an answer about being wrong.

   Where candidates lose it

   Choosing a loss you can blame on an external shock. That avoids the question. Pick one where the error was yours and where the lesson changed a specific habit.

   Expect next

   • Was that a bad decision or a bad outcome?
   • What do you do differently now?
   • How long did it take you to change your mind?

10. 098What is an area of coverage you would want, and why that one?Career and fitIntermediatefirst roundMorningstarEquity Research · Chicago · 2023Carlyle GroupGeneralist · New York · 2015

    Say this

    Name a sector, give a reason rooted in the analytical work rather than in interest, and show you know what covering it actually involves. Then say you would take whatever coverage they need.

    Then walk it

    1. Pick something specific: not 'technology' but 'enterprise software' or 'semiconductor capital equipment'. Specificity signals you know the sector has sub-structures.
    2. Give an analytical reason: 'the disclosure is rich enough to build a real variant view, because net retention and cohort data are published' or 'the cycle is long enough that patient work pays off'.
    3. Show you know the work: what data you would track, who the players are, what the key debate in the sector is right now.
    4. Connect it to something you have done. Coverage preferences are more credible when backed by a model you have built or a company you have followed for a while.
    5. Then be flexible, explicitly. Juniors rarely choose, and a candidate who will only do one sector is harder to place. 'That is my preference, but the sector matters less to me than the team and the process' is the right close.
    6. If you know which sectors they are hiring for, weight your answer toward those without pretending it was always your passion.

    Where candidates lose it

    Naming a sector because it sounds exciting, then being unable to name its key metrics or current debate. The follow-up is immediate. Pick the one you have actually done work on.

    Expect next

    • What is the key debate in that sector right now?
    • What metric would you track weekly?
    • What if we put you in a sector you did not choose?
