Group interviews are used because they surface behaviours that individual interviews can't. How you interact with strangers under pressure, whether you listen as well as you speak, how you handle being talked over or dismissed — all of this is visible in a group exercise in a way that answers to questions are not.
The mistake most candidates make is treating the group exercise like an individual interview — trying to dominate, prove themselves, and "win." It tends to backfire. The candidates who get hired are usually not the loudest; they're the most effective collaborators.
What assessors are watching for
Assessors during group exercises typically score against a competency framework. Common behaviours they're looking for:
Contribution. Are you present in the discussion? Do you make points that move the group forward? Saying nothing is worse than saying something imperfect.
Active listening. Do you build on what others say, or do you wait for your turn to speak and ignore what came before? The strongest candidates reference colleagues' points and extend them.
Communication quality. When you speak, is it clear and purposeful? Rambling, repeating yourself, or talking over others are all marked against you.
Collaborative behaviour. Do you include quieter members? Do you support good ideas from others (even competitors)? Do you help the group get to an outcome, or do you focus on your own performance?
Composure under pressure. If you get disagreed with or talked over, how do you respond? Gracefully or defensively?
Common mistakes and what they signal
Talking constantly. Candidates who feel compelled to fill every silence signal anxiety and poor listening. Assessors notice who speaks most — but they score quality over quantity.
Being passive and saying almost nothing. Equally bad. If you're barely present, you give the assessors nothing to score. Contribute at least every few minutes with something substantive.
Ignoring other candidates. Speaking only to the assessors and not engaging with colleagues shows you don't actually know how to work in a team.
Being aggressive toward other ideas. Disagreeing is fine. Dismissing is not. "I see that differently" beats "that's not right."
Changing your position constantly to match whoever spoke last. Shows you lack conviction and are trying to please rather than contribute.
How to balance speaking and listening
A rough mental framework: aim to contribute meaningfully every two to three minutes. Between contributions, focus genuinely on what's being said. This rhythm — contribute, listen, contribute, listen — is more effective than dominating and less risky than being silent.
When you contribute, aim to do one of three things: add new information, synthesise what's already been said and point the group in a direction, or ask a question that moves the discussion on. These are all high-value contributions that assessors notice.
What to avoid: restating what someone just said but louder, disagreeing without an alternative, or making points that take the group backwards rather than forward.
Handling group dynamics
If someone dominates: Don't compete with them directly. Wait for a natural pause and use a bridging phrase: "Building on that point — I'd also add..." or "I want to make sure we've also considered..." This is visible to assessors as confident, collaborative behaviour rather than aggression.
If someone is very quiet: Bringing them in is a positive leadership signal. "I'd be interested to hear [name]'s view on this" or "We haven't heard from everyone yet" shows you're thinking about the team, not just your own performance.
If the group gets stuck: Step up and structure. "We've got five minutes left — should we decide between these two options and move to a recommendation?" Facilitation is a high-value contribution that's often more visible than individual arguments.
