Define Observation, Interpretation and Decision

A candidate enters a graduate recruitment centre, smiles at the receptionist, sits with both hands tucked beneath the table and becomes noticeably quieter when asked about a six-month gap in their CV. Within seconds, an interviewer may convert these observations into a story: unprepared, hiding something or not resilient. The professional skill is not noticing less; it is keeping the observation, the interpretation and the decision separate long enough to find out what the behaviour actually means.

An observation is a description of what a camera, microphone or reliable witness could record: ‘the candidate paused for approximately three seconds, looked down toward the table and rubbed the left side of their neck.’ An interpretation is a provisional hypothesis about what that behaviour may reflect: ‘the question may have produced discomfort, uncertainty or cognitive load.’ A decision is an action with consequences, such as progressing the candidate, asking for clarification, recording a concern or rejecting the application.

These layers are related, but they are not interchangeable. ‘He is hiding something’ is not an observation; it is an interpretation, and ‘do not hire’ is not evidence; it is a decision that requires job-relevant justification and fair process. Navarro’s framework is especially useful here because it treats pacifying behaviours as clues to stress or discomfort that may guide questioning, while warning that pacifiers alone are not definitive proof of deception [Navarro, What Every Body Is Saying].

The same movement can have different meanings in different contexts. A candidate who crosses their arms in a cold assessment room may be regulating temperature; a candidate who crosses them while leaning forward and maintaining an engaged gaze may simply be sitting comfortably; a candidate who suddenly closes their posture after a sensitive question may be experiencing discomfort, fear of being judged or the effort of retrieving information. Meaning is therefore not contained inside the gesture like a label on a box. It emerges from timing, context, the person’s usual behaviour and the surrounding cluster of signals.

This sequence prevents the interviewer from jumping directly from a visible cue to a consequential decision. In practical terms, you first record what changed, then ask whether the behaviour differs from the candidate’s own baseline and whether several channels shift together. Only then do you form a tentative interpretation and choose an action that is proportionate, such as asking the candidate to explain the timeline in their own words.

A baseline is not an ideal standard of confident interview behaviour. It is the candidate’s own pattern during relatively low-stakes conversation: how they normally sit, gesture, pause, speak, orient their body and use eye contact. Navarro recommends allowing initial nervousness to settle and establishing a baseline once pacifying behaviours have decreased and stabilised [Navarro, What Every Body Is Saying]. This matters in HR because some candidates fidget, avoid sustained eye contact or speak softly as part of their ordinary style, while others become visibly still under pressure.

Consider the difference between ‘the candidate avoided eye contact’ and ‘the candidate looked toward the interviewer during low-stakes questions but looked down repeatedly when discussing the employment gap.’ The second note is stronger because it contains a comparison and a topic link, while still avoiding a conclusion. Even then, the change could reflect embarrassment, grief, language-processing demands or concern about being misunderstood; it tells you where to ask, not what to believe.

Imagine that Lina, a graduate applicant, is relaxed during introductions and describes a university project with frequent hand gestures, steady speech and an upright posture. When the interviewer asks, ‘Why did you leave your first placement after only three months?’, Lina becomes still, presses her lips together, looks down and rubs her forearm. The disciplined record is: ‘After the placement question, gesture rate decreased, speech paused, gaze shifted downward and forearm rubbing began; these behaviours were not observed during the preceding questions.’

The premature interpretation would be ‘Lina was dismissed and is lying.’ A more responsible interpretation is: ‘The placement topic appears to have produced a multi-channel change from Lina’s earlier baseline; possible explanations include discomfort, uncertainty, concern about disclosure or cognitive effort.’ The appropriate next action is not an automatic rejection, but a neutral request for chronology and context, followed by assessment of the answer against the published role criteria and the same process used for other candidates.

Your most useful professional sentence may be the least dramatic one: ‘I observed a change linked to this topic, and I need more information.’ That sentence protects the candidate from mind reading and protects you from confirmation bias. It also keeps the interview constructive: you can remain curious, ask a fair question and document the answer without pretending that non-verbal behaviour has delivered a complete explanation.
