Why a Shared Hobby Can Skew a Hiring Decision
A candidate mentions trail running, and the interviewer lights up: they run the same routes. The conversation gets easier. That ease can quietly change how the candidate is judged—not because running says anything about their ability to do the job, but because familiarity feels like evidence.
People often respond more favorably to those they see as similar to themselves. In an interview, a common interest can create rapport and make a candidate seem more likable, trustworthy, or capable. That spillover is sometimes called the halo effect: a positive impression in one area influences judgments in another. The interviewer may then give a polished answer more credit, or overlook a weak one, without realizing the hobby has shifted the standard.
The Cost of Mistaking Rapport for Evidence
Hiring is a decision under uncertainty: employers have limited time to predict how someone will perform. When a personal connection becomes a shortcut, the process can reward candidates who share an interviewer’s tastes rather than those who best meet the role’s requirements. That can exclude qualified people and leave an organization with a poorer match for the work.
The bias does not require deliberate favoritism. It can arise in an ordinary conversation, especially when interviews are loose and different candidates are asked different questions. A shared hobby is memorable; relevant evidence—such as how someone solved a job-related problem—can be harder to compare unless the process makes room for it.
Keep the Conversation, Separate the Score
Interviewers can still use small talk to help candidates feel at ease. The key is to assess everyone against the same job-related criteria: ask consistent questions, take notes on specific answers, and score those answers against a rubric. Work samples or practical exercises can add another view of a candidate’s skills.
The shared hobby may make an interview more pleasant. It should not make the candidate’s qualifications look stronger than they are.
