Early turnover is a screening signal, not a people problem

When someone leaves in the first three months, one of a few things almost always happened. The job was not what the posting described. The candidate could not actually do the core work at the level claimed. Or the working conditions, schedule, or management style were a surprise. Each of those is something a disciplined screen can surface before the offer, and each is something a keyword-matching resume filter will sail right past.

The three mismatches behind most 90-day quits

The role was oversold

A posting written to attract as many applicants as possible tends to describe the job you wish you were offering, not the one that exists. The candidate accepts based on the posting, arrives to the real thing, and leaves. The fix is not a prettier posting. It is writing the requisition from the work backward: the three problems this person will own in year one, the actual tools, and the real constraints.

The skill was claimed but not current

A resume can be structurally true and still misleading. Someone who used a skill five years ago and lists it flat next to skills they use daily is not lying, but they are not ready either. Automated screens reward the keyword and cannot tell recency from history. A short work-sample or scenario question tied to the actual job catches this in minutes.

The conditions were a surprise

Shift patterns, on-call expectations, travel, or how decisions get made are rarely in the posting and almost never in the resume screen. When they surface on day 5, the new hire recalculates. Naming the two or three least popular realities of the role during the interview, on purpose, trades a few more declines up front for far fewer 90-day quits later.

Why the resume screen cannot catch any of these

An applicant tracking system (ATS) matches words. It cannot judge whether a skill is current, whether the posting matched the job, or whether the candidate understood the conditions. Those are human judgments, and they belong at the front of the funnel, not after a bad hire has already cost you a quarter.

Reading your own early-turnover data

Your 90-day quits are a report card on your screening. Pull the last year of them and look for the pattern. If they cluster in one role or one hiring manager, the posting or the interview is oversold. If they span roles but share a could-not-do-the-work theme, your screen is rewarding keywords over recency. If exit notes mention surprise about hours or expectations, you are not naming the hard parts early enough.

Three checks that prevent most of them

1. Write the requisition from the work backward, and describe the role honestly, including the least popular parts.

2. Add one short skills-recency check tied to the real job, not a trivia quiz.

3. Verify the two or three claims the role actually depends on, rather than the whole resume.

None of this slows hiring in any way that matters. It moves the cost. A few more honest declines before the offer is a trade every employer should take against a seat that empties out at day 89.
