Candidates are skilled at describing themselves as collaborative. But collaboration is a relational trait - it only exists in the context of other people's experiences of working with you. This is why targeted referee questions about teamwork are one of the most valuable and underutilised verification tools in the hiring process. The right questions, directed at the right referees, can confirm or fundamentally contradict the team player narrative a candidate has constructed throughout the interview process.

Who to Ask

The referee selection matters as much as the questions. For teamwork verification, a mix of referee types provides the most complete picture:

• Direct managers can speak to how the candidate behaved under authority and whether they supported team goals over personal ones when the two conflicted.
• Peers and colleagues have the most direct experience of day-to-day collaboration - including the behaviours that rarely surface in manager-observed contexts.
• Direct reports (where applicable) reveal whether collaborative behaviour extends downward in the hierarchy or was reserved for impressing those above.

Requesting at least one peer referee from the candidate, alongside the more standard manager reference, dramatically increases the reliability of collaboration verification.

The Questions to Ask

Generic questions produce generic answers. These targeted questions are specifically designed to surface real collaboration patterns:

• "Can you describe a project where [candidate] worked closely with a team? What was their specific role, and how did they interact with teammates?"
• "When this candidate's idea or approach was not adopted by the team or management, how did they handle it? Can you give an example?"
• "How did [candidate] respond when a teammate was struggling with a shared workload - did they proactively help, or did they focus on their own responsibilities?"
• "Was there ever a situation where [candidate] needed to share credit or recognition with others? How did they handle it?"
• "If you had to describe this person's collaboration style in three words, what would they be - and can you give me an example for each?"
• "Would you describe [candidate] as someone who prioritises team success, or are they more individually driven? Can you explain your answer with a specific situation?"

Reading Between the Lines

Referee responses to teamwork questions often contain as much information in their hedging and hesitation as in their explicit statements. Listen for:

• Referees who answer questions about team collaboration with examples that feature only the candidate - no mention of what others contributed
• Unusually brief or vague responses to teamwork-specific questions from referees who are otherwise detailed and forthcoming
• Positive framing that subtly reframes individualistic behaviour as a strength ("very independent, gets things done without needing to rely on others")

These patterns are not definitive, but they warrant a follow-up probe question to confirm whether the ambiguity reflects a real pattern or simply a referee who is not naturally expressive.

Automating Referee Outreach for Collaboration Verification

Structuring and sending custom referee questionnaires manually is time-intensive - Ref Hub's reference check survey builder automates the process - which is why most hiring managers default to the quick phone call that yields almost no useful data. Ref Hub's automated reference checking platform sends structured questionnaires to referees digitally, collects structured responses, and presents the data in a format that makes cross-candidate comparison simple.

Download Ref Hub's reference check templates - including collaboration-focused questionnaires - to start building a verification process that actually confirms the teamwork claims your candidates are making.

Conclusion

Teamwork claims are easy to make and easy to fake in interview settings. Reference checks, done with structured, targeted questions and the right referee mix, are your most reliable tool for verifying what candidates have actually been like to work with. Make the investment - and trust the data over the interview performance.
