A new hire fails in the first 90 days because of attitude, culture fit and chemistry — not because they lacked experience. CPG Recruitment has built teams across 25+ industries in Canada and the US since March 2020, and the pattern holds almost everywhere: the reasons people are let go inside their first quarter are rarely the reasons they were assessed on before they were hired. That gap between what an interview measures and what the job actually punishes is where early turnover comes from.

Is a 90-day failure a hiring problem or an onboarding problem?

It is usually a hiring problem that onboarding was asked to fix. Onboarding can lose a good hire — no plan, no owner, no feedback will do it — but it cannot convert someone who was assessed on the wrong criteria into the right person for the role. When employers audit their own early departures, the failure almost always traces back to a decision made in the interview, not to the first week. The practical test is whether the same reason keeps appearing. A single early exit is noise; three in a year is a process.

What does an experience-weighted interview fail to measure?

It fails to measure everything that actually ends employment early. A standard interview allocates most of its time to previous roles, tools, tenure and a walk back through the resume — all of which are verifiable before anyone sits down. What goes unmeasured is coachability, accountability, conflict behaviour and fit with the existing team. Those four are the common causes of a 90-day washout, and they are the four that get squeezed into the last few minutes of an hour, if they are reached at all.

How should an interview be weighted instead?

Around 80% behaviour, culture and chemistry, and around 20% experience. That weighting is the standard CPG Recruitment applies to its own placements, and it is the main driver behind an 87% two-year retention rate across the roles the firm fills. The logic is about sequencing as much as emphasis: experience is cheap to verify asynchronously, so it should be cleared before the interview rather than consuming it. The interview is the only stage that can observe how a person actually behaves, so it should be spent almost entirely on that.

Which traits should a behavioural interview test for?

The traits that cannot be trained after the hire: accountability, coachability, conflict behaviour and genuine motivation. Each is tested the same way — with questions about situations the candidate has already been through, not hypotheticals, which invite a rehearsed answer. Interviewers should probe for specifics: who else was involved, what the candidate did next, what the outcome cost. Answers that stay general under follow-up are themselves a finding. Panels should also agree in advance what a strong answer looks like, so each interviewer scores against a shared standard rather than a private impression.

What should an employer verify before the interview stage?

Licences, technical floors, hard requirements and references — all of it before the interview, none of it during. Candidate-supplied references deserve particular care, since the list is curated by the person being checked; a reference check that actually tells you something goes a layer past the names provided. Front-loading verification does two things: it protects the interview hour, and it removes the temptation to talk a candidate into a role because the resume was impressive. A structured intake and profile agreed before the search begins is what makes this possible — see how to build an ideal candidate profile.

How should the first 90 days be structured on the employer’s side?

With a named owner, written expectations at 30, 60 and 90 days, and scheduled feedback that happens whether or not there is a problem. A correctly hired person can still be lost in the first quarter by an organisation that has not decided who is responsible for them. Structure also generates early warning: if the 30-day checkpoint is written down, an employer learns at day 30 rather than day 85. For the detail, see what an employee onboarding plan should cover in the first 30 days.

What does a 90-day failure actually cost an employer?

More than the salary paid out, because the salary is the smallest line in it. The real cost is the training hours invested, the productivity the role did not deliver while it was occupied, the disruption to the team that absorbed the work, and the full search repeated from the beginning — including the weeks it takes to get back to a shortlist. Employers running a disciplined, front-loaded process fill roles faster on the second attempt as well as the first: CPG Recruitment cut average time-to-fill from 68 days to 37 across the industries it serves, largely by removing the rework that guesswork creates.

Frequently Asked Questions

Is early turnover always the employer’s fault?

No, but it is almost always the employer’s signal. Candidates leave for reasons outside any process — relocation, a counter-offer, a change at home. What matters is whether the reasons repeat. Repeating reasons point at a process, and a process can be fixed.

Should a 90-day review be formal or informal?

Formal, and written. An informal conversation feels kinder but leaves both sides with different recollections of what was agreed. A short written review at each checkpoint gives the employee something specific to act on and gives the employer a record if the role does not work out.

Can a small business run a structured interview process without an HR department?

Yes. Structure is a set of decisions, not a department: agree the profile before posting, verify hard requirements before the interview, use the same behavioural questions for every candidate, and score against a written standard. Most of the discipline costs nothing but the decision to do it in that order.

Does this apply to hourly and frontline roles as well as salaried ones?

It applies most sharply there, because turnover in hourly and frontline roles is where early departures compound fastest. The weighting does not change — attitude and fit still decide who stays — though the verification step is usually shorter and the interview correspondingly more important.

Early turnover is an interview problem before it is a management problem. CPG Recruitment designs and runs behaviour-weighted hiring processes for employers across 25+ industries in Canada and the US, from the candidate profile through to the 90-day checkpoints.
