How to Prepare for a Group Interview Exercise
Prepare for a group interview exercise: read the brief, contribute useful ideas, handle disagreement and help the group reach a clear response.

In a group interview exercise, your preparation needs to cover working through a task with other candidates, not just answering questions alone. Follow the organiser’s instructions: exercises differ, and this guide is a practice aid, not a description of every employer’s scoring system.
Oxford University’s assessment-centre guidance advises candidates to read the brief carefully and listen to others. The practice task below is invented. It does not come from Oxford or from any employer.
Check what you are being asked to prepare
Read the invitation before practising. Find out the format, duration, required preparation and materials you may use. If information is missing, ask the recruiter rather than assuming that online research, prepared notes or outside assistance will be allowed.
For an online session, check the joining instructions and practise using the platform’s relevant controls. Keep the organiser’s contact details available for connection problems. If you need an accessibility arrangement, contact the organiser early to discuss what can be arranged; do not assume a particular adjustment has been approved. You can ask whether instructions are available in another format.
Prepare to work independently within the assessment rules. Do not obtain leaked task materials or upload a confidential brief to an outside service. Do not use AI assistance unless the organiser has explicitly allowed it.
Turn the brief into a shared task
When the exercise begins, use the reading time provided. Identify the required output, constraints and deadline. A recommendation, a ranked list and a presentation are different deliverables; avoid spending the session solving the wrong problem.
If the instructions allow discussion, suggest a short check of the group’s understanding. Illustrative wording: “Are we choosing one option and explaining our reasons, or ranking all of them?”
Use only the facts supplied or research explicitly permitted. Label any assumption the group needs to make. Do not invent a budget, customer preference or technical capability to rescue your preferred idea.
Practise a contribution that moves the task forward
Fictional rehearsal task, not a real assessment: a group must recommend a room for a volunteer induction. Room A has more seats; Room B has space for the small-group activity required by the brief. Both meet the stated attendance requirement. No price information is supplied.
You might contribute: “Both rooms meet the attendance requirement. I favour B because the brief asks for small-group work. We cannot compare cost from the information given.”
Another participant might identify a constraint you missed. Check it against the brief before responding. Change your recommendation if the new information warrants it. The point of the exercise is to practise explaining a choice, not to memorise this answer.
You can also contribute by connecting ideas, spotting a missing requirement or summarising an unresolved choice. If roles are assigned, follow them. Otherwise, do not assume you must appoint yourself leader or speak for the longest time.
Handle interruptions and disagreement
Listen to the substance of other contributions. Refer to the idea and its evidence rather than making comments about the person. If two proposals compete, suggest comparing them against the same requirement from the brief.
Illustrative wording: “Could we check both options against the delivery requirement before deciding?” If you have been interrupted, a brief “May I finish the reason for that suggestion?” can return attention to your point. If you interrupted someone, stop and let them finish.
Offer space for others without putting a particular person on the spot: “Is there another concern we have not considered?” Avoid taking over someone else’s assigned task.
Leave time for an accurate final response
Help the group check its recommendation against the requested output. Note unresolved assumptions rather than claiming certainty. If you present the conclusion, distinguish agreed points from outstanding differences; do not invent consensus.
After a practice session, ask your partners for one concrete observation about how you contributed and one thing to try differently. Did you use the brief, explain a reason, respond to another idea and help complete the task? These are rehearsal prompts, not an employer’s marking scheme. Choose one specific change to practise next time.
