Case Study Interview Finance: UK Guide to Assessment Centre Case Tasks and Presentations
Case study interviews test judgement under time pressure, not full models. This UK guide covers solo case formats, recommendation structure, and presentation tactics at assessment centres.
Candidates often confuse case studies with technical exams. They either over-model and run out of time, or ramble without a recommendation. Banks use solo cases at assessment centres because analyst work includes synthesising incomplete information and advising under deadlines.
This guide focuses on individual case study interviews: formats, analysis structure, presentation, Q&A defence, and practice plans. For group tasks, see our group exercise assessment centre guide. For inbox simulations, see the e-tray exercise finance guide.
Where case studies appear in UK recruiting
| Stage | Format | Typical timing |
|---|---|---|
| Assessment centre | On-the-spot solo case + presentation | 45 to 75 minutes total |
| Final-round superday | Shorter live case discussion | 15 to 30 minutes |
| Take-home (some firms) | Written memo or slides | 24 to 72 hours |
Case prompts often mirror real advisory questions:
- Should Company X acquire Target A, B, or C?
- Debt vs equity to fund expansion?
- Should the bank pitch for this mandate?
- Invest or pass on this company?
The decision type matters less than how you structure uncertainty.
What assessors score
| Dimension | Strong signal | Weak signal |
|---|---|---|
| Problem framing | States decision and criteria upfront | Jumps to numbers without objective |
| Analysis | Prioritises key drivers | Reads every page equally |
| Judgement | Names trade-offs explicitly | False certainty |
| Communication | Clear recommendation first | Circular narrative |
| Composure | Handles Q&A revisions calmly | Defensive when challenged |
Technical depth is usually moderate. Communication and judgement often dominate.
The six-step case framework
Use this sequence in solo cases:
1. Clarify the decision (two minutes)
Write at the top of your notes:
- What exactly are we deciding?
- For whom (client, bank, investor)?
- What is the time horizon?
If instructions are ambiguous, state your interpretation aloud before analysing.
2. Set criteria (three to five minutes)
Pick three to four factors, for example:
- Strategic fit
- Valuation / affordability
- Execution risk
- Financing flexibility
Criteria prevent random analysis.
3. Extract facts from the pack (fifteen to twenty-five minutes)
Scan for:
- Revenue and margin trends
- Leverage and liquidity
- Market context
- Synergy or integration risks
- Management quality signals
Do not recopy every table. Flag three insights and one risk per option.
4. Compare options qualitatively (ten to fifteen minutes)
A simple comparison grid in notes:
| Option | Upside | Risk | Fit with criteria |
|---|---|---|---|
| A | ... | ... | ... |
| B | ... | ... | ... |
Directional valuation is enough: "A is cheaper on EBITDA multiple but carries integration risk."
5. Recommend with caveats (five minutes)
Structure:
- Recommendation: one clear choice
- Two reasons: criteria-linked
- One risk: what could change your view
- Next step: what diligence you would run
6. Present and defend (five to fifteen minutes)
Open with the recommendation, not background.
Presentation structure (three to five minutes)
Minute-by-minute outline:
| Minute | Content |
|---|---|
| 0-0:30 | Decision + recommendation |
| 0:30-2:00 | Key evidence (two points) |
| 2:00-3:00 | Main risk and mitigation |
| 3:00-4:00 | Optional: alternative rejected and why |
| 4:00+ | Q&A |
Use plain language. Assessors are not scoring slide design. They are scoring clarity.
Q&A: how to handle pushback
Common challenges:
| Interviewer push | Strong response |
|---|---|
| "Why not Option B?" | Acknowledge B's strength; explain criteria weighting |
| "Your valuation seems high" | Separate directional view from missing diligence |
| "What if synergies fail?" | Downside case and impact on recommendation |
| "You had ten minutes left. What else?" | Name one diligence workstream, not new analysis rabbit hole |
Revising your view calmly can score well. Arguing without evidence does not.
Case study vs technical interview
| Case study | Technical interview |
|---|---|
| Open brief, messy data | Defined questions |
| Judgement and structure | Accounting and valuation fluency |
| Presentation matters | Verbal precision matters |
| "What would you advise?" | "Walk me through depreciation" |
Refresh technical basics with our investment banking technical interview questions guide, but do not turn cases into formula recitation.
Commercial context strengthens cases. Apply second-order thinking from our commercial awareness finance interview guide when sector or macro appears in the brief.
Take-home case studies
Some firms assign cases in advance. Standards rise:
| Element | Expectation |
|---|---|
| Depth | Cleaner logic, more explicit assumptions |
| Output | Short memo or slide deck |
| Numbers | More defensible if you cite them |
| Time management | Do not over-build; answer the question |
Still lead with recommendation. A beautiful model with no answer fails.
One-week case prep plan
| Day | Task |
|---|---|
| 1 | Read one public M&A deal; write invest/pass memo (one page) |
| 2 | Timed solo case: acquisition choice (45 min) |
| 3 | Record three-minute presentation; review clarity |
| 4 | Timed solo case: debt vs equity financing |
| 5 | Mock Q&A with partner pushing on risks |
| 6 | Full mock AC block: case + one group exercise |
| 7 | Light review; sleep before real AC |
Build cases from live UK/Europe deals in the news. Real context beats generic textbook companies.
Common case study mistakes
| Mistake | Why it fails | Fix |
|---|---|---|
| No recommendation | Looks indecisive | State a view; qualify risks |
| Full DCF under time pressure | Runs out of clock | Directional comparison |
| Ignoring the question | Answers wrong decision | Write decision at top of page |
| Presenting chronologically | Buries the lead | Recommendation first |
| Reading slides | Low executive presence | Bullet notes + eye contact |
| Ignoring Q&A | Misses half the score | Practise defence separately |
Link case prep to your application tracker
Case briefs often reflect sectors you flagged on your CV or division you applied to. When you track applications by company and division, you can rehearse sector-relevant cases instead of generic templates.
Practise one forty-five-minute solo case this week and record a three-minute recommendation-only presentation before your assessment centre.
