How to Evaluate Soft Skills in an Interview (Without Just Going on Vibes)

Soft skills are genuinely important and genuinely hard to evaluate well — a candidate can claim to be a strong communicator or collaborator in an interview regardless of whether it's true, and "they seemed nice" is a weak, unreliable basis for an actual hiring decision.

Ask for a specific behavioral example, every time

"Are you a good communicator?" invites a rehearsed yes. "Tell me about a time you had to explain something complex to someone without the relevant background" asks for a real, specific memory that's much harder to fabricate convincingly, and the quality of the actual explanation given in the interview is itself a live demonstration of the skill being assessed.

Watch how a candidate handles a genuinely difficult or unexpected question

A candidate's composure and clarity when asked something they clearly weren't expecting or don't have a polished answer for reveals more about real communication and problem-solving under pressure than any rehearsed answer to a predictable question. This isn't about trying to trip someone up — it's about noticing what happens when the script runs out.

Cross-reference self-reported soft skills against reference checks

A reference check is one of the few tools that can genuinely verify a soft-skill claim independently of the candidate's own self-presentation — asking a reference for a specific example of how the candidate handled team conflict or a difficult stakeholder conversation gets at something an interview alone can't fully confirm.

Use structured, consistent questions across candidates for the same role

Evaluating soft skills through unstructured gut feeling is exactly where interviewer bias creeps in most easily — a candidate who reminds the interviewer of themselves reads as a stronger "communicator" almost by default. A consistent set of behavioral questions, scored against a defined rubric, closes much of this gap the same way structured interviewing does for any other trait.

Distinguish interview performance from the actual on-the-job skill

Some candidates interview exceptionally well without that necessarily translating to strong day-to-day collaboration, and some genuinely strong collaborators interview less smoothly due to nerves or interview-specific unfamiliarity. Weighing concrete past examples and reference-verified behavior more heavily than raw interview charisma produces a more accurate signal than charisma alone.

Give soft skills real weight in the scoring rubric, not just an afterthought

If soft skills matter for a role, they deserve a defined place in the structured scorecard with real evaluation criteria — not an unscored 'gut check' column that ends up dominating the final decision informally anyway. Making the criteria explicit is what allows soft-skill evaluation to be consistent across interviewers rather than reverting to whoever's personal impression is loudest in the debrief.
