EY Case Interview Practice: Free Case and Prep Resources
EY's own interview tips say its interviews typically run 30 to 45 minutes on video and are behavioral, a case study, or both: you read a sample business scenario, then discuss it with your interviewer. EY Consulting publishes no practice case, while EY-Parthenon Australia publishes an example case for its blind strategy interviews.EY (opens in a new tab), read ; EY-Parthenon (opens in a new tab), read

Picking Robots Decision: A grocery distributor's picking robots or night shift
EY's interview tips describe the case study interview as a sample business scenario you read and then discuss with your interviewer. Candidates report EY Consulting cases on operations and technology that end in a rollout plan, so this one does. The full version is MetroFresh Distribution Center Operations Turnaround, an original library case. EY (opens in a new tab), read
1Step 1: Read the case
A regional grocery distributor ships to its stores from one distribution centre. Orders keep growing, pickers fall behind and trucks leave late. The COO is choosing between adding a night shift of pickers and installing goods-to-person picking robots, and wants your recommendation and how to roll it out.
2Step 2: Ask clarifying questions
Open a question to hear the interviewer's answer.
What does the COO need, and by when?
Interviewer: Every truck leaving on time by next peak season, about nine months away, at the lowest yearly cost. She will fund a one-off investment if it pays back within four years.
How much picking is there?
Interviewer: About 40,000 order lines a day today, rising to 48,000 next year. A picker does 400 lines a day by hand, and there are 100 pickers.
What does a picker cost?
Interviewer: 50,000 a year fully loaded, no currency given. Night shift pickers cost 20 percent more.
What would the robots do?
Interviewer: They bring shelves to fixed stations, where a picker does 1,000 lines a day. They suit 60 percent of lines, the small items; the rest stay manual. One-off cost 6 million, plus 0.5 million a year to run.
Anything that could slow the rollout?
Interviewer: Installation takes six months and closes one zone while it runs. The warehouse management system needs an upgrade first, and staff are worried about jobs.
3Step 3: Structure your answer
Take two minutes. Lay out how you would decide between the two options and what the rollout must cover, then say your first hypothesis.
2:00
Show what a strong structure covers
Plays the goal back: on-time trucks by peak season, lowest yearly cost, payback inside four years.
Capacity: pickers each option needs for 48,000 lines a day, and whether it is ready before peak.
Economics: yearly labour and running cost of each option, the one-off cost and the payback.
Rollout risk: the six-month install with a zone closed, the system upgrade first, a bridge until it is live.
People: what happens to pickers whose work moves to robots, and how staff are brought along.
Ends with a hypothesis, for example robots for small items with a temporary night shift as the bridge.
4Step 4: The interviewer's next question
How many pickers does each option need at 48,000 lines a day, what does each cost a year, and what is the robots' payback?
Show what a strong answer does
By hand: 48,000 / 400 = 120 pickers, the 100 today plus 20 on nights at 60,000, so 5.0 + 1.2 = 6.2 million a year. Robots: 60 percent is 28,800 lines at 1,000 a day, about 29 pickers, and 19,200 manual lines at 400 is 48, so 77 pickers at 50,000 is 3.85 million plus 0.5 to run, 4.35 million. The saving is about 1.85 million a year, a payback of about 3.2 years, inside the four-year line. Then the rollout: the install takes six months and needs the system upgrade first, so run a night shift as the bridge through peak and move pickers to robot stations rather than cut them.
Flour costs rose 18% on a $4M flour bill, and prices went up 3% on $20M of sales. How much margin did Harbor lose?
Your answer
Flour went up by about $720K and the price rise brings in $600K, so the net hit is roughly $100K.
What worked
Split the change into a cost side and a price side before adding them up.
Could improve
$720K minus $600K is $120K, not $100K: state the exact net before rounding.
Model answer
Flour: 18% of $4M is $720K more cost. Price: 3% of $20M is $600K more revenue. Net margin loss: $120K.
Next time, say this
Cost is up $720K and price brings back $600K, so Harbor loses $120K of margin.

The EY interview process, and what trains each step
1
Application
EY US says recruiters review your academic background, skill set and work experience, and that the process then varies by role, experience level and service line. US early-career candidates are asked to apply to no more than two jobs in six months, so pick the Consulting team that fits.
EY Australia's online assessment is an immersive simulation with multiple choice, slider and video questions, no time limit but typically 45 to 60 minutes in one sitting, followed by personalised feedback on your strengths. EY UK runs its own online assessment first, and EY US says some routes add a written assessment.
EY's interview tips say interviews are typically by video, last 30 to 45 minutes, and are a behavioral interview, a case study interview or a combination of both. In the case study you read a sample business scenario and then discuss it with your interviewer.
Recruitment day with a group activity (Australia, New Zealand)
Shortlisted students meet one or two EY team members for a 45 to 60 minute behavioural and motivational interview, and may work with two to four other students on a fictional case study. EY says there is no single correct answer: it watches how the group collaborates and communicates.
Experienced hires: hiring team, then senior stakeholders (UK)
EY UK's experienced-hire process usually runs initial screening, interviews with the hiring team and sometimes a final stage with senior stakeholders or partners. You may be asked for a presentation, case study or technical assessment; case and scenario questions assess analytical thinking, commercial awareness and how you approach real business problems.

10 EY-style interview questions
In our words, not EY's, grouped by the formats EY names and the work its Consulting teams describe, with what a strong answer does. EY gives no official questions to match, so work these, then the library cases linked under them.
Case study: technology and transformation
EY US Technology Consulting covers platforms, AI and data, digital engineering and cybersecurity; Business Consulting covers transformations.
1A retailer wants to replace its order system. Should it launch everywhere at once or store by store?
What a strong answer does: Weighs speed of benefit against risk of a failed launch, picks a phased rollout with a pilot and a go or no-go gate, and names the metric that releases the next wave.
2A bank asks whether automating loan document checks is worth the investment. How do you build the business case?
What a strong answer does: Sets the one-off and running cost against hours saved and error cost avoided, computes a payback, and says which assumption, usually the automation rate, would flip it.
3A client bought new software a year ago and few people use it. What do you look at?
What a strong answer does: Separates the tool (does it fit the work), the people (training, incentives) and the process around it, then checks usage data by team before recommending a fix.
EY US Business Consulting covers supply chain, operations and finance; Risk Consulting covers risk management, compliance and controls.
4A distribution centre is missing its truck departures. Where do you look first?
What a strong answer does: Compares capacity with demand step by step (receiving, picking, loading), finds the bottleneck with numbers, and only then proposes a fix and its cost.
5An insurer must cut operating cost by a tenth in two years. Which levers come first?
What a strong answer does: Splits cost by type and activity, ranks levers by size, speed and risk, and says the order it would pull them in and what it would leave alone.
6A utility failed an audit of its data controls. How do you prioritize the fixes?
What a strong answer does: Ranks the findings by the risk each leaves open and the regulator's deadline, fixes the highest-risk ones first, and assigns an owner and a date to each.
7A chart shows cost per order falling while total cost rises. What do you test first?
What a strong answer does: Checks volume and mix first, since unit cost can fall while volume grows faster, before concluding anything about efficiency.
EY Australia and New Zealand: a fictional case with two to four other students, no single correct answer.
8Your group splits between two options in the first minutes. What do you do?
What a strong answer does: Proposes the decision criteria first, tests both options against them out loud, and builds on others' points so the group reaches a call in time.
EY judges each answer on a relevant experience, the action you took and what it led to.
9Give an example of a time you had to learn something new quickly to deliver.
What a strong answer does: Names the situation briefly, spends most of the answer on what you did, and ends on a result with a number or a consequence.

Prepare for both formats EY names, because its own interview tips say each interview is behavioral, a case study or a combination, typically 30 to 45 minutes on video. Read EY's "Tips for your EY interviews" first, then train the steps your route uses: the online Job Simulation in Australia and New Zealand, a group case on recruitment day, and for the case, operations and technology problems of the kind EY Consulting's teams work on, ending with a recommendation and a rollout. Write ten to fifteen behavioral examples with an action and a result. On Road to Offer the sample case on this page runs in your browser with no account; a free account includes 1 full AI-graded case, such as MetroFresh Distribution Center Operations Turnaround; Corvane Air and Halvering Valley Hospital are worked operations cases with a model answer for every question and need no account. Firm-style cases are practice cases written for Road to Offer or adapted from university consulting club casebooks, not the firm's own cases.
Where can I practice EY-style case interviews for free?
EY Consulting publishes no practice case, so use a free case of the kind it describes. The sample case on this page, a distribution centre deciding between picking robots and a night shift, runs in your browser with no account: clarifying answers, a two-minute timer and what a strong structure covers. MetroFresh Distribution Center Operations Turnaround is the full case, run out loud with an AI interviewer or step by step; your first full case is free with a free account, no card. Corvane Air and Halvering Valley Hospital are free to read with a model answer for every question, no account. They are general practice cases picked for EY Consulting's operations and technology work, not EY's own cases.
Does EY Consulting use case interviews?
Sometimes, depending on your route. EY's interview tips say an interview may be behavioral, a case study or both, and EY US early careers says rounds may include prerecorded video, live video and case study interviews based on business needs. EY Australia and New Zealand students do a fictional case as a group activity rather than a one-on-one case, and EY UK experienced hires may get a case study, a presentation or a technical assessment. Your invitation tells you which.
What is the EY case study interview like?
EY describes it as a sample business scenario that you read through and then discuss with your interview facilitator, inside an interview that typically runs 30 to 45 minutes on video. EY publishes no example or scoring for it; EY UK says case and scenario questions assess analytical thinking, commercial awareness and how you approach real business problems. Candidates report EY Consulting cases on technology rollouts, operations and cost that end with how to implement the answer.
Is the EY consulting case interviewer-led or candidate-led?
EY's pages do not say. Its tips call it a scenario you discuss with a facilitator, and candidates report that EY Consulting interviewers guide you step by step. Practice both: open with your own structure, then answer one directed question at a time with a number and a so-what.
What is the EY Job Simulation?
EY Australia's and New Zealand's online assessment for students: an immersive simulation of realistic work scenarios with multiple choice, rank order, slider and video questions. It has no time limit but typically takes 45 to 60 minutes, EY recommends one sitting, and you get personalised feedback on your strengths. EY UK's first online stage is a Realistic Job Preview followed by a behavioural skills test, with a preparation hub in the assessment portal. Road to Offer has no EY simulator; our EY Job Simulation guide covers the formats.
What happens in the EY group activity?
On an EY Australia or New Zealand recruitment day you may work with two to four other students on a fictional case study inspired by real situations. EY says there is no single correct answer and that it assesses how the group collaborates and communicates. Agree what the group is deciding, build on others' points and help the group reach a recommendation in time.
What behavioral questions does EY ask, and how are answers judged?
EY says it relies heavily on behavioral interviewing, with open questions that start "Give an example of" or "Describe a situation when". It judges each answer on three things: a relevant experience, the action you took, and what it led to, and suggests ten to fifteen examples you can adapt. EY UK recommends the STAR method. Say each story out loud; Road to Offer's fit practice asks the questions with follow-up probes, 1 session free with a free account.
How is the EY Consulting interview different from EY-Parthenon's?
They are separate processes. EY Consulting's teams (Business, People, Risk and Technology Consulting) use EY's general interviews, behavioral, a case study or both. EY-Parthenon Australia, EY's strategy arm, runs two "blind" problem-solving interviews in its first round and publishes an example investment case with suggested answers. If your role is in EY-Parthenon, use our EY-Parthenon interview prep page instead of this one.
Does EY publish practice cases for consulting interviews?
Not for EY Consulting. Its careers pages give interview tips, values and process steps but no practice case or answer key, and the case studies on ey.com describe client work, not interview cases. The only example case on an EY careers page we found is EY-Parthenon Australia's.
How many interview rounds does EY have?
EY does not fix a number. EY US says the process is one or more phone, video and in-person conversations and that the number of rounds depends on business needs. EY Australia and New Zealand students have an online Job Simulation, then an interview or recruitment day; EY UK students an online assessment, then an Experience Day; EY UK experienced hires screening, hiring team interviews and sometimes a final stage with senior stakeholders or partners.
How soon does EY make an offer?
EY US says decisions are usually made soon after the final interview and asks you to tell it if you hold another offer. EY UK says timelines vary by programme, office and volume, and that offers can be placed on a reserve list. EY Australia and New Zealand give no timing.
