1. 090Tell me about a time you did something differently from the way it is normally done.Career and fitIntermediatefirst roundBLBlackRockAsset Management · London · 2026

   Say this

   Choose an example where the standard approach was genuinely inadequate for a reason you can state, where you got the change adopted, and where you can quantify what it saved or improved. Being different for its own sake is not the point; noticing that the default did not fit is.

   Then walk it

   1. Lead with why the normal way was wrong here. Not 'the process was inefficient' but something specific: the standard template assumed a stable base that had changed, or everyone compared the metric the sector reports rather than the one that drives value.
   2. Then the change, in one sentence, and how you validated it before pushing it. Showing you tested the new approach against the old on past data is the difference between initiative and recklessness.
   3. Then the part most candidates skip: getting other people to accept it. Who pushed back, what their objection was, and how you handled it. In an investment firm, a good idea nobody adopts is worth nothing, and this question is partly about whether you can bring people with you.
   4. Quantify the result. Hours saved, errors caught, a valuation that came out materially different, a decision that changed. A number makes the story credible in a way adjectives cannot.
   5. Then the balance that makes you sound safe to employ: say when you would not deviate. Regulated processes, compliance, anything where consistency across a team matters more than local optimisation. Judgement about which conventions exist for a reason is as valuable as the willingness to break the others.
   6. And keep it proportionate. A small, well-validated, adopted change beats a grand claim about redesigning something nobody let you touch.

   Where candidates lose it

   Picking an example of being contrarian rather than being right, or one where you bypassed a process that existed for a good reason. Interviewers at large regulated firms are simultaneously testing initiative and judgement about conventions. Name one situation where you would not deviate, and the story becomes much stronger.

   Expect next

   • How did you get people to go along with it?
   • When would you not deviate from the standard approach?
   • What did it actually save?

2. 091When was the last time you made a data-driven decision, and how do you keep up with markets and finance news?Career and fitCorephone / first roundBLBlackRockAsset Management · Tokyo · 2026

   Say this

   Both halves want specifics. For the data question, name the data, the decision it changed, and the number. For the news question, name a small number of sources you actually use every day and one thing you have been following this week, with your own view on it.

   Then walk it

   1. On the data half, pick something where the data contradicted your prior. That is much stronger than a story where data confirmed what you already thought, because it shows you can be moved by evidence.
   2. Be concrete: the dataset, what you did to it, the number you got, and the decision that changed. 'I pulled ten years of quarterly segment disclosures and found the margin improvement was entirely mix, not cost, so I cut my forecast' is an answer. 'I am very analytical' is not.
   3. Say how you checked it. A candidate who mentions verifying the data source or testing the conclusion a second way sounds like someone who has been burned by a bad dataset, which is a good sign.
   4. On the news half, quality over quantity. Two or three things read daily beats a list of twenty. A wire or major paper, one sector or macro source, and one longer-form read. In India add the exchange filings and a couple of the better independent writers.
   5. Then prove it is real by bringing one live thing: 'this week I have been following X, here is the number, here is why I think the market has it wrong.' That is the part interviewers actually remember, and it converts a screening question into a market conversation.
   6. And have a routine rather than a reading list: morning scan, results-season triage, and a habit of writing a short note on anything you might act on. Process beats enthusiasm in this answer.

   Where candidates lose it

   Listing sources with no evidence you read them. The follow-up is always 'so what did you read this morning', and a candidate who has no answer has failed the whole question. Have one live story with a number and an opinion ready before you walk into any asset management interview.

   Expect next

   • So what did you read this morning?
   • What is your view on it?
   • What data would change your mind?
