An interview should measure behavior first and experience second — roughly 80% behavior, culture and chemistry, and 20% experience. Most interviews do the reverse, because the resume is sitting on the table and it supplies the questions for free. CPG Recruitment has built teams across 25+ industries in Canada and the US since March 2020, and the single most common structural flaw we find in an employer’s hiring process is not the job posting or the salary band. It is an interview that spends its best forty minutes confirming facts a resume already stated.

Why do most interviews measure the wrong thing?

Most interviews measure the wrong thing because experience is easy to ask about and behavior is not. A resume is a ready-made question list: which role was this, why did you leave, what systems did you use, how large was the team. An interviewer can run that conversation without preparing, and it produces the comfortable feeling of a productive hour because the candidate spoke for most of it.

Behavior requires a decision to be made before anyone is scheduled: which behaviors does this role, in this company, actually require? Answering that takes work, and it is work that sits outside the interview itself. When it does not get done, the interview defaults to the document in front of it. The result is a hiring decision made on verified history and unverified character — and character is what almost every failed hire turns out to have been about.

What is the 80/20 interview split?

The 80/20 split allocates 80% of interview time to behavior, culture and chemistry, and 20% to verifying experience. In a sixty-minute first interview, that works out to about five minutes of opening and framing, thirty-five minutes of behavioral questioning, ten minutes confirming the experience claimed on the resume, and ten minutes for the candidate’s own questions and next steps.

The change is not only in the proportions. It changes what the experience portion is for. Experience stops being explored and starts being verified: is what the resume claims real, recent, and relevant to this role. Ten minutes is sufficient for that. The remaining time is where an employer learns the things a reference letter and a work history cannot tell them.

Which behaviors belong in the 80%?

The behaviors that belong in the 80% are the ones that recur in the business every week: ownership of mistakes, coachability, conduct under pressure, and how a person treats colleagues who have no authority over them. These are not universal corporate values pulled from a wall poster. They are the four or five specific traits that separate the employees who thrive in a particular environment from those who quietly disengage.

Identifying them is the same exercise as building an ideal candidate profile, and it belongs at the same point in the process — before the role is posted, not after applications arrive. An interview panel that has not agreed on the behaviors in advance will grade candidates on rapport, and rapport rewards the people who most resemble the interviewers.

What does the 20% still need to cover?

The 20% needs to cover whether the candidate’s claimed experience is genuine and whether it transfers to this role — nothing more. Hard credentials such as licences, tickets, designations and regulated certifications should not consume interview time at all; they belong in the application screen, so that everyone who reaches an interview already clears the legal and technical floor.

Where experience is preferred rather than required, it should be priced honestly. What an employer buys with prior experience is reduced ramp-up time, which is a genuine benefit with a finite value. It is paid once. A poor attitude is paid for continuously, for the whole tenure of the employee, and it rarely stays contained to the individual — it changes what the people around them believe is acceptable.

How do you score a behavioral interview fairly?

Score it with the same written questions for every candidate, and have each interviewer record their scores independently before the panel discusses anyone. Consistency is what converts a set of individual impressions into a genuine comparison. Without it, the candidate interviewed most recently holds an advantage over the first for no reason other than recall.

Independent scoring matters more than most panels expect. When the most senior person in the room gives their view first, the other assessments reorganise themselves around it, and an employer ends up with one opinion presented as four. Scoring first and discussing second is also where a drifting hiring standard becomes visible, because the drift shows up as a gap between what the scorecard says and what the room wants to do.

How does a structured interview shorten time-to-fill?

A structured, behavior-first interview shortens time-to-fill because it removes the cause of most hiring delay, which is indecision rather than sourcing. Processes stall at a fourth and fifth round when nobody in the room can articulate what is wrong with a candidate who reads well on paper. That unnamed reservation is almost always a behavioral concern with nowhere to go, because the interview never defined the behaviors it was assessing.

Designing processes this way is a significant part of how CPG Recruitment reduced average time-to-fill from 68 days to 37 for the employers it works with. Disagreement between decision-makers does not disappear. It simply surfaces on a scorecard in the first week, where it can be resolved, instead of after a month of additional interviews. The same principle is what stops a slow search from turning into a desperation hire two months later.

When should an employer bring in outside help?

An employer should bring in outside help when the same role keeps failing, when the hiring panel cannot agree on what good looks like, or when interviews are being designed in the room on the day. Those three symptoms all point at the same missing asset: a defined, written interview built around agreed behaviors, applied the same way every time.

That asset does not have to be built from scratch by a business owner between operational fires. It can be designed once, documented, and handed to whoever runs interviews from then on — which is the practical difference between a hiring process a company owns and a hiring habit it repeats.

CPG Recruitment designs interview processes for employers across Canada and the US — defining the behaviors worth measuring, writing the questions that surface them, and building the scorecard that keeps a panel honest. You can speak to our team about your hiring process, or look at done-for-you recruitment if you would rather hand the whole search over. For the founder’s perspective on the same question, Christian Saab has written about whether you should hire for attitude or experience on his personal site.

Frequently Asked Questions

How many people should interview each candidate?

Two or three is the practical range for a first interview: whoever holds final approval, and at least one person who will work with the hire day to day. The arrangement to avoid is a decision-maker who never meets the candidate but retains a veto at offer stage, which is one of the most common reasons a search restarts after weeks of work.

Should every candidate be asked the same questions?

Yes for the core behavioral set, which is what makes candidates comparable and what protects an employer if a hiring decision is ever challenged. Follow-up questions should differ, because they chase whatever the candidate actually said. The fixed questions produce the comparison; the follow-ups produce the depth.

Can a behavior-first interview work for high-volume hiring?

It can, provided the behavioral set is shortened rather than abandoned. For high-volume roles, three or four behavioral questions in a twenty-minute structured screen will separate candidates more reliably than a longer unstructured conversation, because the scoring stays consistent across interviewers and across days.

How do you document an interview without slowing the process down?

Use a one-page scorecard with the agreed behaviors listed, a numeric rating for each, and two lines of evidence per rating. It takes an interviewer about five minutes immediately after the candidate leaves. Documentation slows a process down only when it is written from memory days later, which is also when it stops being accurate.
