Your finance interview is in three days. You open a list of financial modeling interview questions, then another tab, then ten more. An hour later, you have collected a syllabus.

The practical problem is deciding what deserves the next hour. You cannot learn every finance job in a weekend. You can understand this role, practise a representative task, and make your existing experience easier to explain.

Here is the plan I would use: three focused hours a day, nine hours in total. Adjust it to your schedule and starting point. If the employer has specified a case, presentation, or assessment format, that instruction takes priority.

Suggested three-day interview plan, three hours each day: map the role, practise a relevant task, rehearse and repair.

WSM suggested schedule: nine focused hours across three days. Adjust for the actual interview format and your starting point.

The 60-Second Version

  • Day 1: translate the job description into three skills you must demonstrate.

  • Day 2: complete one role-relevant task and explain the result aloud.

  • Day 3: rehearse, fix the weakest answers, and prepare your questions. Use AI for practice with facts you can verify.

1. Day 1: turn the role into a short evidence list

First 45 minutes: decode the job. Read the description and mark the verbs: forecast, reconcile, value, analyse, present, monitor. Identify who uses the work and what decision it supports.

Choose the three capabilities you most need to demonstrate. For an FP&A role, these might be explaining performance, building a forecast, and working with non-finance colleagues. For equity research, the priorities may include accounting, valuation, and communicating an investment view.

Next 60 minutes: research the business and team. Use the firm's public materials and the actual role description. Write why this specific work interests you. Be ready to connect that interest to something you have done or want to learn, rather than a generic statement about reputation.

Next 45 minutes: prepare three real examples. Choose a problem you solved, an error you corrected, and a situation requiring collaboration. Explain your own contribution, the outcome, and what you learned. A university project is fine if you identify it honestly.

Final 30 minutes: find your largest gap. Test yourself aloud. Finish Day 1 with one page: the role, three required skills, three examples, and the weakness you will address tomorrow.

2. Day 2: do one piece of the work

Spend 30 minutes refreshing the concepts behind your weak area. Spend 90 minutes completing one relevant task. Use the final 60 minutes to check it and explain the answer aloud.

Choose the task from the role:

  • Investment banking: Build a simple valuation comparison and explain the enterprise-to-equity bridge.

  • Equity research: Prepare a short stock pitch with a valuation range and a risk that could change your view.

  • FP&A: Explain a budget variance and update one forecast assumption.

  • Credit: Test whether operating cash generation can cover debt payments under a downside case.

Example practice tasks by role: investment banking valuation bridge, equity research stock pitch, FP&A budget variance, credit debt repayment scenario.

Illustrative task choices. Employer instructions and the specific team's remit come first.

For a small FP&A warm-up, suppose budgeted volume was 1,000 units at $50 and actual volume was 900 at $52. Budget revenue was $50,000; actual revenue was $46,800, a $3,200 shortfall.

Using budget price for the volume effect gives −$5,000. Using actual volume for the price effect gives +$1,800. Together they reconcile to −$3,200. State that convention; price-volume bridges can allocate the interaction differently.

Now explain why volume missed and whether it should change next month's forecast. The arithmetic is the opening of the discussion. The causes require evidence.

3. Use AI to rehearse questions you can verify

AI can make the practice more interactive. Give it the public role description and your own non-confidential case, then ask for one question at a time. Ask it to challenge unclear assumptions and point out where your explanation does not answer the question.

Check the corrections. If it proposes a formula, recompute it. If it claims the company recently changed strategy, verify that in company materials. Confident feedback is not automatically accurate feedback.

Keep your examples truthful. A tool can help organise a real project; it cannot supply experience you did not have. Avoid uploading private employer data, and follow the employer's rules on tools during any assessment.

For ongoing practice after this interview, FMV Core + AI brings together modeling foundations and AI workflows. For the next three days, the immediate priority is finishing and understanding your chosen task.

JPMorganChase's interview guidance emphasises research, rehearsal, and specific experience relevant to the opportunity. That is a useful anchor for this plan: produce evidence you can discuss, then practise discussing it.

4. Day 3: simulate the interview, then repair the weak answers

Spend 60 minutes on a mock interview and debrief. Use a friend, a recording, or an AI practice session. Include your introduction, why this role, one technical task, one behavioural example, and a difficult follow-up.

Spend 60 minutes fixing the two weakest answers. Rebuild the calculation you fumbled. Remove unnecessary detail from the story you could not finish. Check a claim you made from memory.

Spend 30 minutes on questions for the team. Ask what a good first three months looks like, which work a junior person owns, and how work is reviewed. These help you evaluate fit while showing that you understand the responsibilities.

Use the final 30 minutes for logistics and a closing rehearsal. Confirm the time zone, format, names, location or connection, and requested materials. Finish with a calm run through your opening answer.

Do not turn the final evening into a new curriculum. A rested explanation of material you understand is more useful than another list you have only skimmed.

KEEP BUILDING AFTER THE INTERVIEW

Turn a rushed refresh into lasting skill.

5. Judge your preparation by outputs

Call this Map, Practise, Rehearse. Each day should leave something concrete: an evidence page, a checked work sample, and a set of answers you have said aloud.

Before you stop, answer four questions without looking at notes: Why this role? What relevant work have I done? Can I explain the practice task? What would I check if an assumption changed?

You will still encounter questions you have not prepared. Slow down, state what you understand, ask for missing information where appropriate, and work through the logic. Saying what you would verify is better than disguising a guess as a fact.

Nine hours cannot replace months of skill-building. It can reveal the most important gap and help you present what you already know with more clarity. That is a realistic goal for the time you have.

Reply with the role you are interviewing for and the question you most want to practise. That will help me choose a useful future issue.
