The most expensive sentence in hiring is "I can coach that."
By the time most teams run an assessment, they've already spent weeks getting to know the candidate. So the assessment stops being a filter and becomes a verdict on a decision you've half made. If the candidate looks good, it's validation. If a red flag surfaces, it isn't a stop sign. It's the start of a coaching plan. That isn't a process. It's credit you give yourself for work you've already done.
We see this most in sales hires. A good salesperson is, by definition, good at making an impression. That impression gives the manager a reason to rationalize the hire. Two months later the candidate drops off for the exact issues the assessment flagged on day one.
Part of the problem is how assessments are sold. One-off pricing makes it cost-prohibitive to assess everyone, so managers pick their favorites on paper and assess only the final two or three. The assessment confirms a shortlist instead of building it.
We moved to PeopleBest because they sell by subscription. You can assess every candidate, which means you can build a real process around a predictable cost. Here's what that looks like. A candidate comes in. You have their resume. You send the assessment link, and you or the hiring manager builds a scorecard from three inputs: the resume, the assessment, and the manager's own profile. The scorecard surfaces the gaps:
- Where the resume and the assessment disagree.
- Where the assessment reinforces what the resume claims.
- Where the assessment pushes back on it.
- Where the candidate and the manager share blindsides
That gives you something to track through 30/60/90 onboarding. Progressive data, gathered week over week, keeps the good fits and catches the bad ones early. It offsets the cost of the gap.
The other thing it offsets is the self-blame.
Most managers run 30/60/90 as a loose guideline, not a go/no-go. So when someone struggles, the kind manager doesn't ask whether the fit was wrong. They ask what they failed to do. That question has a mechanism behind it, and the mechanism is worth naming.
Will and skill, and the wrong hat
Most of the time you keep someone too long, you didn't misjudge their ability. You misread a will problem as a skill problem. And you can't train your way out of a will problem.
When a good employee stalls, the reflex is to teach them again. That works if the gap is skill. They want the outcome and need the how, so you show them, watch them try, and reinforce what lands. Call that the trainer.
Will is a different gap, and it wears a disguise. Someone who can do the work and isn't doing it doesn't need another lesson. They need structure and a direct conversation. Call that the supervisor. Teach a will problem again and you only add noise, and the noise reads to you like progress.
Two more cases round it out. Someone who can do the work and wants to needs neither a lesson nor a push. They need room. You give them agency and step back. Call that the coach. And someone who can't do the work and doesn't want to is the hardest case of all. Before anything else, they need a relationship and an honest conversation about whether this is the right seat. Call that the mentor.
Four situations, four different jobs. You are familiar with these four leadership hats, you wear them. The trouble is that a distortion picks the wrong one for you. "They should know this by now" sends you in as a supervisor when they needed a trainer. "She's sharp, she'll figure it out" sends you in as a coach when they needed to be shown. Managers catch themselves doing this constantly. You wear the wrong hat, get no result, and instead of questioning the diagnosis, you decide you didn't teach hard enough.
A leader I was talking with recently put it better than I can. Looking back on someone they'd just let go, they said what that person had actually needed was a mentor. They didn't have the skill, and they didn't want the work. The manager had spent months trying to train someone who was never in the training quadrant.
The fix isn't a better lesson. It's a better question. Stop asking "why aren't you doing this?" That assumes skill and lands as an accusation. Ask "are you willing to do this?" The answer tells you which hat to wear, and whether there's a hat that works at all.
This is the same misread that made you rationalize the hire in the first place. "I can coach that" is just "this is a skill gap I can train." Sometimes it is. Sometimes it's a will gap, and no amount of coaching closes it. A consistent process tells you which one you're looking at before you've spent six months finding out.
And the team already knows. They're carrying the work while you decide. So when someone finally gets let go, the response usually isn't "why did that happen?" It's "what took us so long?"
If any of this sounds like your week, it might be worth a conversation. Or maybe the status quo is working, and it's best left alone.
