A consulting assessment centre is a half day or full day event where a firm scores you across several exercises at once, usually a group exercise, a case study, a presentation, and a final interview. This guide covers all 8 exercises you might face, how the format differs at every major firm, and how to prepare for each one.

Key Takeaways

 

A consulting assessment centre is the final selection stage at Big 4 and large technology consultancies, where several assessors score you across multiple exercises in a single sitting.

 

• Expect a mix of group work, an analytical case task, a presentation, and a senior interview, all scored separately

 

• Deloitte, PwC, KPMG, EY, and Accenture all run one, but each uses a different name and a different exercise mix

 

• McKinsey, BCG, and Bain do not run assessment centres, so preparing for group exercises is wasted effort for MBB

 

• You are scored against the firm's published criteria, not ranked against the other candidates in the room

 

• PwC and KPMG both explicitly ban AI assistance during their assessments and check for it

 

• The exercise most candidates underprepare for is the group exercise, and it is the one assessors watch hardest

 

What Is a Consulting Assessment Centre?

 

A consulting assessment centre is the final stage of a consulting firm's recruitment process, where shortlisted candidates complete several assessed exercises in one event. Trained assessors observe you across a group task, an individual analysis or case study, a presentation, and an interview. The term describes the process, not the venue, and events run virtually or in a firm's office.

 

The logic behind the format is simple. A single interview gives a firm one data point from one assessor, while an assessment centre gives it four or five data points from three or four different people. That redundancy is why firms trust it for their final hiring decision.

 

The competition feeding into that decision is intense. The Institute of Student Employers reported that UK employers received an average of 140 applications per graduate vacancy in 2025, up 14% year on year and the highest figure since it began collecting the data in 1991. By the time you reach the assessment centre, the firm has already cut the vast majority of the pile.

 

One clarification matters more than anything else in this article. An assessment centre is not the same thing as a final round of case interviews, and candidates who confuse the two prepare for entirely the wrong day.

 

Which Consulting Firms Run Assessment Centres?

 

Big 4 firms and large technology consultancies run assessment centres. Strategy houses generally do not. The table below covers the five firms that account for most assessment centre invitations in consulting.

 

Firm	Event name	Format	Main exercises
KPMG	Launch Pad	In person, half day	Group exercise, analytical exercise, interview with a senior member of the firm
PwC	Virtual assessment centre, then business assessment	Virtual, then in person	Group activities, individual case study tasks, then an in-office interview with a senior leader
EY	Experience Day	Virtual or in person, up to a full day	Case study, group exercise and discussion, final strengths based interview
Deloitte	Final stage assessment	Virtual or in person, 1 to 2 hours	Prepared 5 minute presentation, questions on it, then a skills and motivation interview
Accenture	Assessment centre	Virtual or in person, half day	Group exercise, individual strengths interview, business scenario or prepared topic discussion

 

Formats change between recruiting cycles, so always treat your invitation email as the authority. KPMG's Launch Pad shifted from an all day virtual event back to an in-person half day, and PwC restructured its process so that the assessment centre is now the penultimate stage rather than the last one.

 

Why McKinsey, BCG, and Bain Are Different

 

MBB firms do not run assessment centres. Their process is resume screen, online assessment, then two rounds of one-on-one interviews, each combining a case and a personal experience discussion. There is no group exercise, no in-tray task, and no cohort of candidates sitting in a room together.

 

The screening tool differs by firm rather than the interview format. McKinsey uses Solve, BCG uses an online case assessment, and Bain uses tests such as SOVA or TestGorilla depending on the region.

 

Candidates in the UK and Europe sometimes call an MBB final round an assessment centre because several interviews are scheduled on the same day. That is a scheduling convenience, not an assessment centre. If you are preparing for MBB, put your hours into a case interview practice plan and skip everything in this article about group dynamics.

 

What Happens on the Day of a Consulting Assessment Centre?

 

A typical half day assessment centre opens with a briefing, moves through two or three assessed exercises, and closes with a senior interview. You are assessed from the moment you arrive, including during coffee breaks and lunch. Below is a realistic schedule for a half day event.

 

Time	Activity	Assessed?
8:45am	Arrival and coffee with current consultants	Not formally scored, but assessors form first impressions
9:15am	Welcome and firm briefing	No, but the content often reappears in your interview
9:45am	Group exercise with 4 to 6 candidates	Yes, usually by two assessors taking separate notes
11:00am	Individual case study or analytical exercise	Yes, scored on your written or presented output
12:15pm	Lunch with the recruiting team	Informally, and recruiters do feed impressions back
1:00pm	Interview with a partner, director, or senior manager	Yes, and this is usually the heaviest weighted stage
2:00pm	Close, questions, and next steps	No, though your questions still register

 

The unassessed segments matter more than candidates expect. In my time running recruiting at Bain, the informal conversations were where genuine enthusiasm and genuine indifference both became obvious, and that read reached the decision meeting whether or not it appeared on a scoresheet.

 

What Are the 8 Consulting Assessment Centre Exercises?

 

There are 8 exercises that appear across consulting assessment centres. No single firm uses all 8, and most events combine three or four. Read your invitation carefully, because it usually names the exact exercises you will face.

 

1. The Group Exercise

 

You are put in a team of four to six candidates, given a business problem and a short brief, and asked to reach a recommendation in 30 to 45 minutes. Assessors sit outside the group and score each person individually. This is the closest thing in Big 4 recruiting to a group case interview.

 

The single biggest misconception is that you win by dominating. You do not. Assessors are scoring whether you move the group toward a decision, and the person who talks most while contributing least scores badly.

 

The highest scoring behaviours are structuring the discussion in the first two minutes, bringing in quieter candidates by name, tracking the clock, and summarising where the group has landed before time runs out. If nobody has volunteered to keep time, take it. It is an easy, visible contribution that nobody resents.

 

2. The Case Study or Written Exercise

 

You receive a pack of information about a client situation, typically 5 to 20 pages of text, exhibits, and financials, and you have 45 to 90 minutes to produce a recommendation. This is functionally a written case interview, and the output is either a short written memo or a set of slides you present afterwards.

 

Time management decides this exercise. Spend the first 10 minutes skimming everything and deciding what the client actually needs to know, then work backwards from the recommendation you expect to give.

 

Assessors reward a clear answer supported by two or three pieces of evidence over an exhaustive summary with no conclusion. A page of analysis without a recommendation scores lower than a paragraph with one. If you want to get faster at these, my case interview course covers structuring and quantitative analysis in as little as 7 days.

 

3. The Presentation Exercise

 

You present for 5 to 15 minutes and then answer questions. Some firms give you the topic on the day, and others send it a week in advance. Deloitte sits at the prepared end of that range, sending a broad topic roughly a week before the final stage assessment for a 5 minute presentation.

 

Broad topics are harder than specific ones. Five minutes is nowhere near enough for a subject like globalisation or the future of retail, so your first job is to narrow it to a single argument you can defend.

 

Open with your conclusion, give three supporting points, and stop early rather than running over. Assessors score the question and answer section as heavily as the presentation itself, and the same answer-first habit that works in a case interview presentation works here.

 

4. The Role Play or Client Meeting

 

An assessor plays a client, a colleague, or a stakeholder, and you have to handle a scenario in real time. Common setups are a client unhappy with progress, a colleague missing deadlines, or a stakeholder resisting a recommendation you need them to accept.

 

The scoring here is about listening, not talking. Ask what the other person actually wants before proposing a fix, acknowledge their position explicitly, then move to options.

 

Candidates fail role plays by jumping straight to a solution and by taking the assessor's hostility personally. The assessor is testing composure on purpose. Stay warm, stay curious, and treat the difficult behaviour as information rather than an attack.

 

5. The In-Tray or E-Tray Exercise

 

You are dropped into a simulated inbox with 15 to 25 emails, documents, and messages, and asked to prioritise, decide, and respond within a fixed window. Deloitte's job simulation includes an email task of exactly this kind, where you write a professional message under time pressure.

 

Prioritisation is the whole exercise. Sort by urgency and impact before you write a single reply, and be explicit about what you are choosing to delegate or defer.

 

Write in plain professional English, keep replies short, and never leave a high priority item untouched to perfect a low priority one. Finishing 80% of the inbox well beats finishing 40% of it beautifully.

 

6. The Partner or Senior Interview

 

Almost every consulting assessment centre ends with a one-on-one interview with a partner, director, or senior manager. Expect competency and motivation questions rather than a full case, and expect follow-up questions that go two or three layers deeper than the first answer.

 

This interview usually carries the most weight in the final decision. At KPMG, a senior interview is the last gate before an offer, and firms rarely override a negative read from a partner on the strength of a good group exercise.

 

Prepare four or five stories that each demonstrate a different competency, and structure them using the STAR method so the result is never buried. My fit interview course walks through 98% of the behavioural questions firms ask in a few hours.

 

7. Psychometric Retests

 

Some firms re-run numerical or verbal reasoning tests on the day under supervision to confirm your earlier online scores were genuinely your own work. PwC has historically done this in certain regions, running supervised versions of the PwC assessment tests you already completed at home.

 

Do not assume this stage is a formality. If your online score came from a rushed attempt, a supervised retest will expose the gap, so keep practising timed numerical questions right up to the event.

 

The best preparation is the same as for the original test. If you already cleared the Deloitte online assessment or an equivalent screen, redo a handful of timed questions the week before to keep your speed intact.

 

8. Informal and Social Segments

 

Coffee breaks, lunches, and networking slots are listed as unassessed and function as assessed anyway. KPMG explicitly builds non-assessed activities into Launch Pad so candidates can meet partners and trainees, and those conversations still shape how the room feels about you.

 

Have three or four genuine questions ready about the work, the office, and the team. Asking a consultant what a bad week looks like tells you more than asking about the graduate scheme structure, and it signals that you are thinking about the job rather than the offer.

 

Do not treat these as a break from being professional, and do not spend the whole time talking to the other candidates.

 

What Do Assessors Actually Score You On?

 

Assessors score you against a published list of firm competencies, exercise by exercise, using a numerical scale. Each exercise maps to two or three competencies, and your scores are pooled in a wash-up meeting once every exercise is finished. You are measured against the standard, not ranked against the other candidates.

 

That last point is the one candidates get wrong most often. Every person in your group can pass, and every person in your group can fail. Treating the room as competition produces exactly the behaviour that loses marks.

 

The competencies themselves are named differently at every firm but cover the same ground.

 

• Structured problem solving: breaking an ambiguous brief into clear, logical parts before analysing anything

 

• Analytical and numerical judgement: reading data accurately and knowing which number actually matters

 

• Communication: saying the answer first, then the reasoning, in language a client would follow

 

• Collaboration and inclusion: building on other people's ideas and bringing quieter voices into the discussion

 

• Resilience under pressure: staying composed when the brief changes or the group stalls

 

• Motivation and commercial curiosity: showing you understand what the firm does and why you want that specific work

 

KPMG publishes its skills framework openly, and candidates who reach Launch Pad receive feedback against it. Read whatever your firm publishes before the day and use their vocabulary in your answers.

 

Having sat on the other side of the table, I can tell you the notes assessors write are more specific than candidates imagine. They are not recording a general impression. They are recording that you restated the objective at minute three, or that you never checked the time.

 

How Do You Prepare for a Consulting Assessment Centre?

 

Prepare in three passes: research the firm and its criteria two weeks out, drill the specific exercises one week out, and rehearse logistics the day before. Most candidates spend all their time on the interview and almost none on the group exercise, which inverts the actual risk.

 

Two Weeks Out: Research and Structure

 

1. Read the firm's own process page: PwC, KPMG, EY, and Deloitte all publish what their assessment stages involve, and it is more current than anything else you will find
   
   
2. Write down the competencies: list the firm's published skills or values and map one story from your own experience to each
   
   
3. Learn the business area: know the difference between the service lines and be able to say why you chose yours
   
   
4. Read two recent client stories: pick real projects from the firm's website so your motivation answers reference actual work

 

This research also protects you in the group exercise. Candidates who understand the firm's business make sharper contributions on the case, because they recognise which trade-offs a consultant would actually care about.

 

One Week Out: Drill the Exercises

 

Run at least two timed group discussions with friends, even if that means recruiting people outside consulting. The skill you are building is speaking up early and summarising cleanly, and it does not transfer from solo practice.

 

Do three timed written cases and force yourself to produce a recommendation every time. Set a 45 minute timer, work from a data pack, and write a one page answer. Reviewing common case interview frameworks helps here, as long as you adapt them rather than applying them wholesale.

 

Rebuild your mental maths. Assessment centre analysis rarely goes beyond percentages, growth rates, and breakeven calculations, but doing them without a calculator under time pressure is a skill that decays. Twenty minutes of case interview math drills a day is enough.

 

Finally, rehearse your competency stories out loud rather than in your head. Written stories always sound polished. Spoken ones reveal whether you can land the result in under 90 seconds.

 

The Day Before: Logistics and Rest

 

Confirm the format, the address or the video link, and the start time. Test your camera and internet connection if the event is virtual, and check your travel route if it is in person.

 

Prepare your questions in advance. Having four thoughtful questions to ask in a consulting interview ready removes the worst moment of the day, which is being asked what you want to know and having nothing.

 

Then stop preparing. Assessment centres reward alertness and stamina far more than one extra hour of cramming, and a tired candidate makes visible mistakes in the group exercise.

 

What Are the Biggest Mistakes Candidates Make?

 

Most assessment centre failures come from behaviour rather than ability. Across the hundreds of candidates I have coached one-on-one, the ones who get cut are usually capable people who misread what the day was testing.

 

Mistake #1: Treating the group exercise as a competition

 

Interrupting, dismissing other people's points, and racing to speak first all read as poor collaboration. Assessors score you individually, so undermining the group only lowers your own marks.

 

Mistake #2: Going silent to avoid mistakes

 

The opposite failure is just as costly. An assessor cannot score contributions you never made, and a candidate who says three sensible things in 40 minutes has given them almost nothing to write down.

 

Mistake #3: Analysing without concluding

 

Candidates run out of time in the case study because they read everything before deciding anything. Commit to a working hypothesis early and test it, rather than mapping the whole data pack first.

 

Mistake #4: Preparing generic motivation answers

 

Saying you want variety, smart colleagues, and steep learning describes every firm on the market. Name the service line, name a project type, and explain the connection to something you have actually done.

 

Mistake #5: Relying on AI during the assessments

 

This one now carries real consequences. PwC UK states that using AI tools or third party assistance to generate, edit, or complete assessment responses is not permitted, that it reviews applications for indicators of AI assisted support, and that it will withdraw candidates and may notify academic institutions or professional bodies. KPMG requires candidates to confirm they completed assessments independently and re-tests elements of its online assessments.

 

Mistake #6: Switching off during the informal parts

 

Candidates who are polished in the exercises and disengaged over lunch create a jarring impression. The consistency across the whole day is part of what the firm is buying.

 

What Should You Wear and Bring?

 

Wear business professional unless your invitation says otherwise. For consulting assessment centres in the UK, that means a suit or smart separates in a neutral colour, and firms increasingly write the expected standard directly into the joining instructions.

 

Read those instructions rather than guessing. Some firms now specify business casual, and turning up in a full suit to a business casual event is a smaller error than the reverse but still noticeable. If nothing is specified, default to the more formal option and follow standard consulting interview dress code conventions.

 

Bring a notepad, two pens, a printed copy of your CV, photo identification, and a bottle of water. Leave your phone in your bag once the day starts.

 

For virtual events, the rules shift slightly. Dress the same from the waist up, sit somewhere with a plain background and no interruptions, and join five minutes early so a technical problem does not become your first impression.

 

What Happens After the Assessment Centre?

 

Assessors meet after the event to compare scores and reach a decision, and turnaround is faster than most candidates expect. KPMG states that successful Launch Pad candidates receive an offer within two working days, and unsuccessful candidates can request feedback.

 

Other firms take longer because more stages follow. PwC matches successful candidates to a business area and office, schedules a recruiter call, then runs an in-person business assessment with a senior leader before any offer is made.

 

Ask for feedback if you are rejected, and ask for it specifically. Firms that score against published competencies can usually tell you which one you scored below the bar on, and that is far more useful than a general note about a strong candidate pool.

 

A rejection at this stage is not the end of the road at that firm either. Deloitte welcomed around 1,500 graduates and apprentices across 17 UK locations in its 2025 intake, and firms hiring at that scale re-interview reapplicants every cycle.

 

The consulting assessment centre rewards candidates who prepare for the whole day rather than only the interview, so build your plan around the group exercise and the case study first and treat everything else as reinforcement. Read your invitation email closely, map the exercises it names to the sections above, and start rehearsing out loud today.

 

Frequently Asked Questions

 

How long does a consulting assessment centre last?

 

Most consulting assessment centres run for half a day, roughly three to four hours. KPMG runs Launch Pad as an in-person half day event. EY Experience Days and some PwC and Accenture events run closer to a full day, from about 9am to late afternoon. Deloitte is the outlier, with a final stage assessment scheduled for around one to two hours.

 

Do McKinsey, BCG, and Bain run assessment centres?

 

No. McKinsey, BCG, and Bain run back-to-back one-on-one case and fit interviews rather than group assessment days. You will not sit a group exercise or an in-tray task at MBB. Some European offices schedule several interviews on the same day and candidates call that an assessment centre, but the content is still individual case interviews.

 

What is the pass rate for a consulting assessment centre?

 

No major firm publishes an assessment centre pass rate, so treat any specific number you see online as an estimate rather than fact. What is documented is the volume feeding into it. The Institute of Student Employers reported an average of 140 applications per graduate vacancy in 2025, so only a small fraction of applicants reach the final stage at all.

 

Are consulting assessment centres virtual or in person?

 

Both formats are in use and it depends on the firm. PwC UK runs a virtual immersive assessment centre followed by an in-person business assessment in the office you are matched to. KPMG moved Launch Pad back to in-person events at venues across the UK. Always check your invitation email, because firms change format between cycles.

 

Can you use AI to prepare for a consulting assessment centre?

 

You can use AI to prepare, but not during the assessments themselves. PwC UK states that using AI tools or third party help to generate or edit assessment responses is not permitted and that it reviews applications for indicators of AI assisted support. KPMG requires candidates to confirm they completed assessments independently and withdraws candidates found to have acted dishonestly.

 

What happens if you get a difficult group in the group exercise?

 

You are scored against the firm's criteria, not ranked against the people in your group, so a dominant or silent group does not automatically sink you. If one candidate is talking over everyone, the highest scoring move is to bring quieter people in by name and redirect the group to the task. Assessors notice who restores order far more than they notice who talks most.
