Deloitte cases are candidate-led, data-heavy, and shaped by the practice you apply to. Work through a full Deloitte-style workforce case step by step, check your math as you go, and compare your answers to a model response.

Deloitte Consulting is organized into practice groups, and your case usually reflects the one you applied to. Strategy cases look like classic MBB cases. Technology cases focus on digital and systems decisions. Human capital cases focus on workforce and organization questions.
Deloitte cases are generally candidate-led. You set the structure, ask for data, and push toward a recommendation without waiting to be prompted.
Prep guides describe Deloitte cases as data-heavy, often with several exhibits per case. Reading charts quickly and pulling out the one number that matters is a core skill.
Deloitte is one of the few large firms that regularly runs a group case, usually in the final round. You are assessed on how you work with others, not only on the answer.
Applying to Monitor Deloitte, the firm's strategy practice? Expect harder cases closer to MBB in difficulty, and in many offices a written case. The Deloitte interview guide covers both tracks.
These five themes cover most Deloitte cases across its practices. Each example prompt below is an original Deloitte-style prompt, not a real interview question. Pick a tab to see how you would structure it and what math to expect.
This is an original case written in the style Deloitte candidates describe, with a human capital focus: a staffing exhibit, cost math, a retention calculation, and a workforce plan. In a live interview you would drive the structure yourself. Here, each step shows the question an interviewer would likely ask next.
Answer each step out loud or on paper before you reveal the model answer. The suggested times match a strong candidate's pace.
Your client is Meridian Health, a system of eight hospitals with $3 billion in annual revenue. Over three years, its spending on agency nurses, who are hired through staffing firms at premium rates, has tripled, and its operating margin has fallen sharply. The CEO has asked Deloitte to reduce agency spending without putting safe staffing levels at risk. How would you approach this?
Take about 2 minutes
Interviewer: How would you structure this?
Agency spending is the gap between the nurses Meridian needs and the nurses it employs, priced at a premium. I would look at:
Take about 2 minutes
Interviewer: Here is Meridian's nurse workforce data. What is the vacancy rate, and what does the data tell you?
| Measure | Value |
|---|---|
| Budgeted nurse positions | 6,000 |
| Filled nurse positions | 5,100 |
| Annual nurse turnover | 22% |
| Staff nurse cost per hour (fully loaded) | $75 |
| Agency nurse cost per hour | $150 |
900 of 6,000 positions are empty, a 15% vacancy rate. Agency nurses fill those shifts at double the cost of staff nurses.
The turnover number explains why the gap persists: at 22%, Meridian loses more than 1,100 nurses a year, so it has to hire a large number just to stand still before it can close any of the vacancy gap.
Take about 3 minutes
Interviewer: Assume each vacant position equals 2,000 hours a year, all filled by agency nurses. How much extra does Meridian pay each year compared with filling them with staff nurses?
900 positions times 2,000 hours is 1.8M hours a year. Each hour costs $75 more through an agency, so the premium is $135M a year.
Total agency spending is 1.8M hours times $150, or $270M, about 9% of revenue. Every vacancy Meridian fills with a staff nurse saves $150K a year.
Take about 3 minutes
Interviewer: Replacing each nurse who leaves costs about $50K in recruiting and onboarding. If Meridian cut turnover from 22% to 15%, how much would it save in replacement costs each year?
Today 22% of 5,100 nurses leave, about 1,122 a year. At 15%, about 765 would leave. That is 357 fewer departures, and at $50K each Meridian saves about $18M a year.
The bigger benefit is indirect. Every nurse who stays is one fewer vacancy to fill, which makes closing the 900-position gap much faster and directly cuts the $135M agency premium.
Take about 2 minutes
Interviewer: What could Meridian do to close the gap?
Take about 1 minute
Interviewer: The CEO asks for your recommendation. What do you tell her?
"Meridian is paying about $135M a year more than it needs to because 15% of its nurse positions are empty and filled by agencies at double the cost. The root cause is turnover: losing 22% of nurses a year means hiring just to stand still. I recommend a retention program aimed at cutting turnover to 15%, which saves about $18M in replacement costs and speeds up hiring, plus an in-house float pool to replace agency shifts. Closing half the vacancy gap would save about $68M a year. The main risk is burnout among current staff during the transition, so the next step is surveying nurses at each hospital to find the main reasons they leave."
Deloitte cases stack several calculations on top of exhibits, so speed and accuracy both matter. Try these four without a calculator, and aim for under a minute each.
A store chain has 4,000 employees and 70% annual turnover. How many people leave each year?
An airline flies 180-seat planes. Fixed cost per flight is $18,000, and each passenger brings in $150. How many passengers does a flight need to break even?
A warehouse ships 2.5 million units a year at a cost of $10M. What is the cost per unit?
Revenue grew from $80M to $92M. What was the growth rate?
Deloitte often adds a group case to the final round. You work with several other candidates on a shared problem, prepare a joint answer, and present it to interviewers who watch the whole discussion.
What interviewers look for is different from a live case. They want to see how you work with others:
Some roles also start with an online assessment before any interviews, so check your invitation for the full sequence.
Learn to structure cases for your practice area, whether strategy, technology, or human capital. Start with the frameworks guide.
Drill math daily, especially percentages, growth rates, and per-unit costs.

It depends on your practice. Strategy candidates get classic cases on growth and profitability, technology candidates get digital and systems cases, and human capital candidates get workforce and organization cases.
In the final round, you may work with other candidates on a shared case and present a joint answer. Interviewers assess how you collaborate as much as the answer itself.
Monitor Deloitte is Deloitte's strategy practice. Its cases are harder and closer to MBB, and many offices add a written case.
Most entry-level processes have two rounds, each mixing behavioral questions with one or two cases, with the group case often in the final round.
No. It is an original practice case written to match the style Deloitte candidates describe. All numbers are illustrative.
