Structured interviews when there is no interview panel

The unstructured interview — a conversation, different questions for each candidate, a judgement formed afterwards — is the default in small businesses and the weakest widely used selection method. It also feels excellent while it is happening, which is the problem: the confidence it produces is unrelated to its accuracy. For broader independent guidance on this point, consult EEOC employment-practices guidance.

Structure is what closes the gap, and structure is cheap. It does not require a panel, a psychologist or software.

What structure actually means

Four things, none of which need a large organisation:

• The same questions, in the same order, for every candidate for the role.
• Questions derived from the essential criteria rather than from the CV in front of you.
• A scoring scale with described anchors, agreed before the first interview.
• Scores recorded during or immediately after each interview, before discussing the candidate with anyone else.

The last point is the one most often skipped and does the most work. Once two interviewers have talked, their independent judgements no longer exist, and the more confident person's view becomes the record.

Ask about what happened, not what would

Hypothetical questions — what would you do if a client complained — measure the ability to describe a sensible-sounding approach. That is a real skill and it is not the same as the skill of handling the situation.

Past-behaviour questions are harder to answer well and harder to fake: describe a time a client complained about something that was your fault; what did you do; what happened; what would you do differently. The follow-ups carry most of the information, because a fabricated example runs out of detail at the second or third probe.

Anchor the scale

A five-point scale with no description means five different things to five people. Write a one-line description of what a low, middle and high answer looks like for each question, before the interviews.

This takes about twenty minutes for a six-question interview and it is the difference between scores that can be compared and scores that record how each interviewer was feeling. It also makes the eventual decision explainable to the candidate and to whoever else has a view.

Two interviewers, independently

Where a second person is available, use them properly: both present, both scoring, no discussion until both sheets are complete. Two independent judgements are meaningfully better than one; two people who talked first are barely better than one.

Where a second person is not available, the substitute is a gap between the interview and the decision. Score immediately, then leave it until the next day before ranking. It does not replicate independence but it does interrupt the momentum of a strong first impression.

Culture fit is where structure collapses

Almost every small business wants to assess whether someone will work well with the existing team, and almost every attempt to do so informally reduces to whether the interviewer enjoyed the conversation. That is a measure of similarity, and similarity hiring narrows a team a little further with each appointment.

If there are behaviours that genuinely matter — how someone handles disagreement, how they work when a task is ambiguous, whether they ask for help — those are criteria, and they get their own questions and their own anchors like anything else. Once written down they usually turn out to be assessable. What cannot be written down was probably not a criterion.

Keep the notes

Interview notes and scores are part of the decision record, subject to the same retention discipline as applications: recorded factually, kept for a defined period, then deleted. Notes written on the assumption that nobody will ever read them are the ones that cause problems later.
