Deloitte already published the practice cases that look like Deloitte. Most candidates still skip them and grind retail margin trees instead, then freeze when the interviewer opens with a federal agency, a ransomware clock, or a legacy architecture migrate-or-die trade. The thesis is simple: treat Deloitte's free case interview prep tool as a shape map of what this firm actually asks, not as optional homework. After that map, you need deliberate math and synthesis reps — including the fully worked original mini-case below — so you are not inventing a profitability tree for a problem that has no revenue lever.
By the end of this page you will know where the official cases live, what Deloitte's own five-step sheet rewards on every answer, which library shapes match which practice group, and how to drive one complete recommendation with invented but consistent numbers. For rounds, timing, and the group exercise, use the Deloitte case interview guide.
Start with Deloitte's own practice cases
Deloitte's careers materials are unusually direct. For entry-level Consultative Offerings roles, the firm points candidates to an interactive practice tool that presents fictional client situations with questions you answer and then check against sample thinking. The durable entry point on Deloitte's US recruiting site is the case prep tool. Deloitte describes these as practice only (not a tracked assessment), with a typical run of about 15 to 20 minutes. The same five-step approach appears on the firm's case and scenario interview tips page.
That is the primary source for this article. Not a third-party casebook. Not folklore from forums. The firm's published library.
As of late 2026, the tool asks you to pick a degree level and an intended area, then surfaces cases tied to that path. Titles that have appeared include Engagement Strategy: Federal Agency V, Strategic Vision: Federal Benefits Provider, Recreation Unlimited, LeadAuto: Market Expansion, Finance Strategy: Federal Health Agency, Talent Management: Federal Civil Cargo Protection Bureau, Architecture Strategy: Federal Finance Agency, MedX: The Smart Pill Bottle, XFintech Inc. Ransomware Attack, Data Exfiltration, Industrial Warehouse Valuation, and Construction Delays: Project Analysis. Deloitte rotates content — open the tool the week before your interviews and treat this list as a snapshot.
Two patterns jump out if you actually click through rather than skim titles. First, a large share of the published set names a federal or public-sector client. That is not a quirk of the practice site; it mirrors a firm that, as of FY2025, reported US$70.5 billion in aggregate global revenue with Strategy, Risk and Transactions up 5.5% and Technology and Transformation up 4.7% in local currency — a portfolio that is not "consumer profitability only." Second, only a minority of the library looks like a classic consumer growth or profitability case. If your entire prep diet is soft-drink pricing and airline load factor, you are training for a subset of what Deloitte shows you for free.
If you are interviewing for Risk and Financial Advisory rather than consulting, Deloitte publishes separate scenario interview preparation. Same idea — practice, not scored assessment — different product line. Do not confuse the two.
What the five-step sheet actually rewards
Deloitte's published tip sheet is blunt about what interviewers are listening for. The firm lists five moves: understand the issue and ask clarifying questions; identify underlying assumptions; summarize specific issues and findings; state recommendations; outline next steps and expected results or impacts. It also says you are not expected to provide the "right" answer, but to convey logic and thought process clearly.
Read that as a scoring instruction, not a pep talk. In a typical first-round room I have sat in, a candidate who lands a defensible answer with visible assumptions and a named next test beats a candidate who lands a cleaner answer opaquely. The sheet has five boxes. A recommendation that stops at "so I would defend the segment" fills one of them and leaves next steps and expected impact blank.
| Step on Deloitte's tip sheet | What the interviewer is listening for | Common miss |
|---|---|---|
| Understand the issue | One crisp restatement plus one or two clarifying questions that change the tree | Asking five polite questions that do not change anything |
| Identify assumptions | Naming the inputs you invented, out loud | Hiding the invented numbers inside the conclusion |
| Summarize findings | A short bridge from evidence to insight | Re-reading every exhibit |
| State recommendations | A decision with a number or a clear trade attached | A list of "options to consider" |
| Next steps and expected impact | The first test after the interview, and what result would change the call | Ending on a slogan |
That last row is where MBB-only prep leaks points at Deloitte. Strategy cases at McKinsey, BCG, and Bain also reward a crisp close, but Deloitte's own careers page literally names next steps and expected impacts as a discrete step. Practice ending every drill with both.
Use the library as a shape map, not a quiz bank
Do not grind every official case until you can recite the sample answers. Use them to diagnose which shapes still feel alien, then close those gaps with timed, graded reps elsewhere.
| Shape in the official library | What it trains | First drill if it feels foreign |
|---|---|---|
| Federal engagement or vision | Scoping under mandate, budget, and stakeholder constraints; mission metric instead of profit | Structure a case with no revenue lever |
| Commercial growth or entry (for example Recreation Unlimited, LeadAuto) | Standard candidate-led strategy with share, margin, and entry-mode math | Market-sizing and profitability trees |
| Technology architecture or digital product | Build versus buy, sequencing, adoption economics — still quantified | Attach a cost and a risk number to every option |
| Human capital / talent | Attrition, capability gaps, workforce planning without a canonical tree | Prioritize segments before listing initiatives |
| Cyber or forensic | Time-pressure prioritisation with incomplete information | State what you would do in the first 24 hours, then why |
| Valuation / project economics | Asset or schedule math and the assumptions underneath | Walk NPV or overrun attribution aloud |
The shape that most candidates under-practice is the public-sector object with no market data: how many claims a benefits agency processes, how many cargo inspectors a bureau needs. That is still market sizing. The drivers change; the discipline does not.
Your practice group changes the case you get
Deloitte consulting recruiting in the US typically routes through practice groups, and the case you receive tends to follow the group you applied to. That is a real structural difference from MBB, where candidates usually draw from a shared case pool regardless of practice interest.
| Practice group | Case flavors you should expect | Failure mode to kill early |
|---|---|---|
| Strategy and Analytics | Market entry, pricing, profitability, M&A, supply chain, business-model change | Reciting a memorized framework instead of naming a first test |
| Technology | Architecture, system replacement, digital product, cyber-adjacent decisions | Going qualitative and never attaching a number |
| Human Capital | Org design, attrition, change, workforce planning | Listing HR initiatives with no prioritization logic |
Match your official-library picks to that row first. A Technology candidate who only practices Recreation Unlimited is training the wrong muscle. A Strategy candidate who never opens a federal title is leaving cheap points on the table the first time the interviewer says "agency" instead of "client company."
One process wrinkle that shows up in some offices: you get a short pack of charts or financials to read before the discussion starts. That is closer to a compressed written case than a pure oral prompt. If you are slow at pulling the one decisive number from a messy exhibit, fix that before you collect more frameworks.
Worked mini-case: Riverbend Health Network
Everything below is invented for practice. The point is the full five-step shape Deloitte describes, with math you can reproduce on paper in under five minutes.
Prompt. Riverbend Health Network runs three community hospitals on three separate EHR instances. Combined beds: 1,200. Combined annual EHR run-rate cost: $18 million. Recommend within 90 days: consolidate onto one instance, or keep three systems and add an interoperability layer. Capital is constrained. Clinical cutover risk is real.
Understand the issue. Choose-and-price under a risk constraint, not a vendor beauty contest. Clarifiers that matter: how much of the $18 million is escapable after consolidation, outage cost per day at the busiest hospital, and whether the board will fund a multi-year program.
Assumptions (invented, stated out loud).
| Input | Figure |
|---|---|
| Consolidation build | $42 million over three years |
| Hard annual savings after go-live | $6.5 million |
| Analytic uplift from one data model | $3.0 million per year (keep separate from hard savings) |
| Dual-run contingency | $2.1 million one-time |
| Interop layer build / annual run | $9 million / $0.9 million |
| Interface costs eliminated by interop | $2.4 million per year |
Structure. Economics of consolidation; economics of interop; residual clinical risk cash cannot decide.
Math. Consolidation hard payback: $42 / $6.5 ≈ 6.5 years. With $3.0 million analytic uplift, effective benefit $9.5 million and payback ≈ 4.4 years. Interop net annual benefit: $2.4 − $0.9 = $1.5 million; payback $9 / $1.5 = 6.0 years. Interop is the cheaper ticket with similar hard-cash payback; consolidation wins only if you count the analytic upside as real, or if three-instance complexity creates risk interop does not fix.
Recommendation. Stage consolidation: migrate the 180-bed hospital first, fund the $2.1 million dual-run, release remaining capital only after 90 days of clean parallel metrics (order errors, med-admin variance, claim denials). Keep interop as the documented fallback. Expected impact if the full program completes: about $6.5 million hard run-rate savings, plus maybe $1.5 million of the analytic claim in the base case until measured, against $42 million of build.
Next steps. Contract review of escapable license spend; dependency map for flagship interfaces; pilot success thresholds written before kickoff. Those three tests keep or kill the staged path.
That shape — issue, assumptions, findings, numbered decision, next steps with expected impact — is what Deloitte's tip sheet asks for. Health-IT is the flavor; the method transfers to any practice group.
Ned's rule. If your recommendation does not name the first test you would run after the interview and the result that would flip your call, you have not finished the case. Deloitte printed that expectation; treat it as scored content, not optional polish.
A two-week practice plan that respects the library
Week one is diagnosis. Open the official practice tool, pick your practice area, and run two cases that match your group plus one that does not. Time yourself. After each case, score yourself against the five steps above. Most candidates discover they are strong on structure and weak on next steps, or fluent on commercial cases and clumsy on federal ones.
Week two is deliberate unevenness. Spend most of your reps on the weak shape from week one. If federal sizing felt alien, do public-sector sizing drills. If technology cases went qualitative, force a cost and a risk number onto every branch. End every drill with a one-sentence decision, one number, and one next test. Then run one full live case out loud — reading solutions does not train mid-case choices under silence.
Practice this today
Open Deloitte's tool and complete one official case in your intended area without peeking at sample answers until you have written your own five-step close. Then run the Riverbend math above cold on a blank page and check whether your payback lands within 10 percent of 6.5 years on hard savings alone.
When you want a graded candidate-led rep with feedback, start with a five-minute first pass at /start (three typed turns, instant scores, no account required), or take the live voice case at /interview (~18 minutes, seven-score debrief). Structure and math drills live at /drills/structure and /drills/math. Everything on CoachNed is open for seven days with no card; then $120 for a recruiting season or $49 a month.

Frequently asked questions
Where can I find Deloitte's official practice cases?
Start from Deloitte's US recruiting case prep tool, also linked from the firm's case and scenario interview tips. Risk and Financial Advisory candidates should use Deloitte's separate scenario interview prep.
Are Deloitte practice cases like McKinsey or BCG cases?
Some commercial titles are close. A large share of the published library is not — federal constraints, technology sequencing, cyber triage, valuation mechanics. Deloitte also publishes an explicit five-step close that names next steps and expected impacts as their own step. Prep that only covers MBB profitability trees leaves those shapes cold.
How many official Deloitte cases should I complete before interviews?
Two or three that match your practice group, plus one that does not, is enough for diagnosis. Repeating sample answers is weaker than timed drills on the shapes you missed.
Does Deloitte track my answers on the practice tool?
Deloitte describes the tool as practice, not an assessment. Use it that way. Your interview performance is what is scored.
What is the difference between the case tool and the scenario tool?
The case tool is aimed at entry-level Consultative Offerings preparation. Scenario prep is aimed at Risk and Financial Advisory interviews. Pick the one that matches the process you were invited into.
