The fastest way to lose a Monitor Deloitte interview is to prepare as if you were interviewing for core Deloitte Consulting. Same parent, same building, different staffing question. Monitor interviewers are deciding whether they would put you on a where-to-play engagement for a CEO; core Consulting interviewers are often deciding whether you can drive an implementation, technology, or human-capital workstream without melting under ambiguity.
Deloitte publishes a five-step case approach that ends on next steps and expected impact. That rubric is firm-wide hygiene and still applies. It is not the Monitor differentiator. After this piece you should be able to separate the Monitor object of work from the broader Consulting case, structure a strategy-shaped live case, and open a written packet the way a Director reads one.
What Monitor Deloitte actually sells
Monitor Deloitte is Deloitte's strategy practice. The firm's own Monitor Deloitte page describes work with chief executives on corporate and business-unit strategy, growth programs, innovation and new businesses, digital strategy as part of business strategy, capability design, pricing, and scenario-based foresight. The US business strategy offering list is blunt: enterprise and business-unit strategy, organic and inorganic growth, business-model innovation, operating-model and capability design.
That is not "help us stand up ServiceNow" or "sequence a multi-year ERP." Those projects live next door inside Technology & Transformation and adjacent Consulting practices. Deloitte as a network reported US$70.5 billion of aggregate global revenue for the fiscal year ending 31 May 2025 and more than 470,000 people. Monitor is a thin strategy layer on a very large professional-services machine. Interviewers notice when your case habits and your "why here" stories only match the machine.
The brand history matters for fit, not for nostalgia. Deloitte completed the acquisition of Monitor's global strategy business on 11 January 2013, after Monitor's US entity had entered Chapter 11. The stated logic in that release was strategy advice plus Deloitte's ability to implement. Your interview still has to show you can do the advice half; execution fluency alone does not get you staffed on Monitor.
How the Monitor case differs from core Deloitte Consulting
Our Deloitte case interview guide covers the published five-step sheet and why the next-steps line separates candidates in a general Consulting case. Keep that close. Then change the object you practice.
| Dimension | Core Deloitte Consulting case (typical) | Monitor Deloitte case (typical) |
|---|---|---|
| Decision type | Improve a process, system, risk posture, or delivery plan | Choose where to play / how to win / whether to build, buy, or partner |
| Success metric | Cycle time, cost, adoption, risk reduction, phased roadmap | Contribution, share, option value, competitive response |
| Live format | Candidate-led conversation; sometimes scenario flavour by practice | Candidate-led oral cases plus, in many offices, a written packet |
| Fit question that fails | Generic "Big Four prestige" | "Why Deloitte" with no Monitor line |
| Wrong rehearsal | Pure consumer P&L with no ops constraint | Technology architecture case with no strategic choice |
Deloitte's recruiting tips page says cases are fictional examples of client work and that the goal is to convey logic, not to hunt a single correct answer. That is true for both tracks. The content still diverges. A Midland Claims Portal backlog case (implementation under a headcount freeze) is excellent Deloitte Consulting practice. It is weak Monitor practice if that is all you run.
Process shape varies by country and hire type. Treat recruiter email as the source of truth. One concrete primary example: Deloitte Sweden's Monitor careers page describes four personal interviews over two days, a reasoning test, a personality test, and both a written case and several oral cases. US and other-market routes are not identical; many candidates report a written packet and a group exercise at finals, but timings and whether Cappfinity-style modules appear are invitation-specific. Do not invent a universal flowchart from campus lore.
The written case is the Monitor filter
In a live oral case, a generous interviewer can rescue a muddy structure with a clarifying question. In a written case you are alone with a packet. Sweden's page is explicit that candidates see a written case in the process. Elsewhere, candidate reports (treat as folklore on exact minutes) usually describe roughly 30 to 50 minutes of prep and then a discussion with a more senior interviewer. The scoring intuition is the same wherever the format appears: can you triage noise, form a point of view, and defend it without chronological storytelling.
What I listen for when someone walks me through a written packet:
- Slide one is the recommendation in one sentence, not a company history.
- One load-bearing number that would flip the answer if wrong.
- Two or three assumptions stated as assumptions.
- A dated next test a partner could staff on Monday.
- A risk that is specific to the competitive or capability context, not "execution risk."
Candidates who spend the prep window polishing a market overview and bury the decision on slide four sound like they are writing a deck for a steering committee that already decided. Monitor work looks more like a memo that forces a choice.
Ned's rule. On a Monitor written case, if a Director can delete your first slide and still not know what you recommend, you failed the format before the math was checked.
Worked example: Northline Industrial coatings (where to play)
Prompt. Northline Coatings sells industrial protective coatings to mid-market manufacturers in the US Midwest. Revenue is $420 million. EBITDA margin is 14%. A PE owner wants a five-year plan. Two options are on the table: (A) build a $55 million specialty coatings plant aimed at food-grade and pharma equipment, or (B) acquire HarborSeal, a $90 million revenue niche player in marine coatings, for 9.0x EBITDA. Leadership wants a where-to-play answer, not a construction schedule.
Clarify (oral) / triage (written). The decision is compete in a new vertical versus buy adjacency, not "how do we implement SAP." Ask for HarborSeal EBITDA, Northline's current food-grade share, and whether the PE hold period is five years with a sale process in year four.
Assumptions (say them). HarborSeal EBITDA margin is 16%, so EBITDA is about $14.4 million and the purchase price is about $130 million. Northline can finance either path. Synergies on the buy are limited to $4 million of cost in year two. Food-grade volume available to Northline without the new plant is small.
Structure. Four peer branches: (1) attractiveness of food-grade / pharma coatings, (2) Northline's right to win (sales force, certifications, reputation), (3) economics of build versus buy, (4) competitive response and exit story for the PE. Test right-to-win before you fall in love with the plant.
Math you can reproduce.
Build path. Suppose addressable food-grade / pharma coatings demand in Northline's reachable geography is $180 million and growing 6% a year. Northline believes it can take 12% share in five years with the plant. Year-five revenue: 0.12 × $180m × (1.06)^5 ≈ 0.12 × $241m ≈ $28.9 million. If contribution margin after variable cost is 35%, year-five contribution is about $10.1 million. Simple payback on $55 million capex at that run-rate is more than five years if ramp is linear; in year three, at half the year-five volume, contribution is roughly $5 million. The plant only clears a five-year PE story if share or margin is higher than the base case, or if the exit buyer pays for a platform story.
Buy path. HarborSeal: $90 million revenue, 16% EBITDA → $14.4 million EBITDA. Price at 9.0x ≈ $129.6 million. Add $4 million of cost synergies in year two → pro forma EBITDA about $18.4 million. Implied entry multiple on synergized EBITDA ≈ 7.0x. If marine coatings grow 3% and margins hold, the asset compounds; if a yard cycle turns down 15% for two years, EBITDA compression hurts harder than a greenfield that never opened.
Recommendation. Do not approve the $55 million plant on the base case. Pursue HarborSeal if diligence confirms customer concentration under 25% and no regulatory landmines on antifouling chemistry. Use the plant only as a contingent year-three option if HarborSeal's commercial team unlocks cross-sell into food processors that already buy marine maintenance coatings.
Next steps (still score this). In 15 business days: top-20 customer calls at HarborSeal, quality-of-earnings, and a one-page right-to-win score for food-grade certifications Northline lacks today. Expected impact if the deal closes at diligence: a marine adjacency with ~$14–18 million of EBITDA and a clearer PE exit narrative than a half-ramped plant. Risk: cultural clash kills the commercial team that is the asset; mitigate with retention packages before signing.
That close is Monitor-shaped: a strategic fork, a number that flips build versus buy, and a next test. It is not an implementation roadmap.
Fit is scored twice and it is not "Why Deloitte"
Case interviewers at Monitor still open and close with motivation. The answer that kills you is a polished Deloitte Consulting pitch: Big Four scale, learning from implementation, path to partner in a large firm. All true for someone else. Monitor's public materials talk about choices, growth, innovation, and senior-executive decisions. Your stories should show you enjoyed forming a point of view under incomplete data, not only delivering against a scope document.
I stop listening when the "why Monitor" paragraph never draws the line to core Consulting. One sentence is enough: you want strategy staffing, you understand Deloitte can implement after the choice, and you are interviewing for the choice half. Then prove it in the case content you choose to practice.
Practice this week
- Write a six-sentence Why Monitor that names the Consulting line you are not joining. Rehearse it with follow-ups on behavioral or the Monitor behavioral guide.
- Run two candidate-led growth or M&A cases on /consulting-cases or the live voice case on /interview. Force a where-to-play recommendation and a dated next test.
- Time one 35-minute written packet of your own: three slides, answer first, one flip number. Use the Northline structure as a template with different figures.
- Skim Deloitte's public case tips so the five-step close stays automatic, then stop practicing Technology implementation prompts unless your invitation names that practice.

Frequently asked questions
Is Monitor Deloitte the same interview as Deloitte Consulting?
No. You share a parent firm and often the same building. Monitor cases and fit questions target strategy staffing; core Consulting cases more often mirror implementation, technology, risk, or human-capital work. Confirm the practice name on your invitation.
Does Deloitte's five-step case approach still apply at Monitor?
Yes as hygiene. Deloitte publishes understand, assumptions, findings, recommendation, and next steps with expected impact. Monitor interviewers still want that close. The differentiator is case content and, in many offices, a written packet, not a different public rubric.
Are Monitor cases interviewer-led like McKinsey?
Usually not. Oral cases are typically candidate-led: you propose the structure and ask for data. Written cases remove the interviewer entirely during prep. Office and hire type can shift the mix; trust the recruiter email over campus summaries.
Will I face online assessments used for other Deloitte campus roles?
Only if the invitation names them. Some campus routes use digital assessments; Monitor processes in some countries emphasize interviews, written and oral cases, and tests of reasoning or personality instead. Skip nothing that appears in your email.
How is Monitor different from Strategy& or EY-Parthenon on interview day?
All three are Big Four strategy arms with strategy-shaped cases and serious fit screens. Formats still differ by firm and office. Prepare the Monitor object of work and the written-packet skill; do not assume another firm's process map transfers.
