Group Exercises

What assessors actually watch — and the two behaviours that fail candidates most.

What it is

Group exercises place 4–8 candidates together for 20–45 minutes to discuss or solve a business scenario while trained assessors watch. Assessors are not looking for the 'right answer' — they are scoring how you work, listen, and interact under realistic pressure. Used by 78% of assessment centre-using employers.

Who uses it

  • Virtually all employers running full assessment centres — investment banks, Big 4, consulting firms, law firms, civil service, technology companies
  • Degree apprenticeship assessment centres at KPMG, Deloitte, EY, PwC, Goldman Sachs, JP Morgan, and similar
  • NHS management and Civil Service Fast Stream assessment centres

What it tests

  • Contribution: frequency and quality of your input — neither dominating nor staying silent
  • Active listening: building on what others say rather than waiting for your turn to speak
  • Analytical quality: proposing clear, reasoned suggestions with quantified impact where possible
  • Collaboration: drawing quieter voices into the discussion by name; managing disagreements constructively
  • Time awareness: keeping the group on track and summarising progress toward the deadline

Common mistakes

Dominating the discussion

Aim for 3–4 substantive contributions in a 20-minute task and keep each one to under 90 seconds. After contributing, explicitly invite a quieter voice: 'Alex, what do you think?' — this shows leadership, not just volume.

Staying silent to avoid conflict

Social loafing is penalised as heavily as domination. If you haven't spoken for two minutes, contribute a summary or clarifying question. Wait for a natural pause, then use inclusive language: 'Let's build on that idea...'

Not listening — waiting to speak

Assessors track whether you build on the previous speaker's point. Begin contributions with 'Building on what [name] said...' and use verbal affirmers ('Absolutely', 'Good point') to show genuine engagement.

Ignoring the brief

Paraphrase the brief to the group before anyone starts contributing — 'So we need to decide X and present Y in 20 minutes, is that right?' This prevents the group spending time on the wrong problem.

Negative body language

Sit upright, relax your shoulders, and maintain roughly 70% eye contact around the table. Assessors are watching your body language between contributions, not just while you speak.

Handling disagreement poorly

Use the acknowledge-then-build pattern: 'I see your point, and perhaps we could also consider...' Never dismiss another candidate's idea directly — assessors score professional disagreement, not confrontation.

Dwelling on errors mid-exercise

Each exercise starts with a clean slate — mentally reset if a contribution lands badly. New task = new scorecard. Use 4-6-4 breathing (inhale 4 s, hold 6 s, exhale 4 s) between exercises to avoid carrying tension forward.

How to prepare

  1. 1Offer structure at the very start: 'Shall we allocate five minutes to brainstorm, ten to decide, and five to summarise?' This shows leadership and gives the group a framework before any disagreement can form.
  2. 2Volunteer as time-keeper or note-taker if no one else does — both roles demonstrate leadership without requiring you to be the loudest voice in the room.
  3. 3Address teammates by name throughout. Assessors notice candidates who build genuine group rapport rather than treating the exercise as a solo performance.
  4. 4Before the exercise ends, give the spokesperson a 10-second summary: 'Our recommendation is X because Y — does everyone agree?' This ensures the group's conclusion is coherent and shows you've been tracking the whole discussion.
  5. 5After the assessment day, send a thank-you email within 24 hours citing one specific highlight, and complete a quick 3-column reflection: what went well, what to improve, one new insight. Feed both into your approach for the next stage.
