Assess: how to tell whether a candidate can actually do the job
Assess is the third letter of the STACK Method. Assess is the work of figuring out whether a candidate can do the job you are hiring them to do. SMB owners tend to over-weight gut feel and under-weight evidence, and they pay for it on the back end when a hire who interviewed well cannot perform the work.
The good news is that structured assessment is not an enterprise apparatus. It is a one-page scorecard, a consistent set of questions, and a look at real work. Building it is less an expertise problem than a time and discipline problem, which is exactly the kind of problem a recruiting partner exists to absorb.
The gut-feel problem
Bad hiring decisions are most often made on the basis of two factors: how comfortable the owner felt in the interview and how confidently the candidate spoke. Both are weak predictors of job performance. Interview comfort measures interview comfort. Confident speech measures confidence in speech. Neither measures whether the candidate can run a punch list, close a deal, manage a P&L, or supervise twelve people through a busy season.
The fix is not to ignore gut feel. The fix is to put it in its proper place: as one input, weighted appropriately, alongside structured evidence.
What structured assessment looks like
Four practices cover most of what a small business needs.
1. The scorecard
Before interviewing, write down what success in the role looks like in twelve months. Three to six outcomes, each measurable. The scorecard becomes the rubric. Every interview question maps to one of the outcomes. Every interview debrief grades against them. The technique is influenced by Topgrading and similar methods, but it does not require the full apparatus. A one-page scorecard solves ninety percent of the problem.
2. The structured interview
Same questions, same order, across every candidate for the same role. Interviewers compare candidates against each other on the same dimensions, not against a moving target. This sounds bureaucratic. It is not. It is the single highest-leverage interview practice that exists, and most SMBs do not use it.
3. The "show me the work" principle
Wherever possible, the candidate does the work in some form during the interview process. A sales hire builds a mock account plan. An estimator estimates a real-but-anonymized project. A plant manager walks the floor and tells you three things they would change. Watching someone do something close to the actual work for twenty minutes tells you more than ninety minutes of behavioral interviewing. When gut feel and what you see in the work disagree, that is information to slow down, not a tiebreaker for going with your gut.
4. Reference checks that actually work
Most reference checks are useless because they ask useless questions. "What was it like to work with Pat?" produces nothing. The questions that produce signal are specific: "On a scale of one to ten, how would you rate Pat's performance?" If the answer is below an eight, ask why. "Who at your company would have rated Pat lower?" gets you the truth most checks miss. References are willing to tell you what is real if you ask in a way that gives them permission.
What personality tests are good for
Personality tests are mostly noise as hiring decision tools. They are useful as conversation starters for onboarding and team dynamics. Predicting job performance from a personality inventory is, in most validated studies, a coin flip with extra steps. Use them after the hire to help the new hire and their manager understand each other faster. Do not use them to decide who gets hired.
A scenario
A fifty-person B2B distributor in Hilliard had two candidates for an inside sales lead. Candidate A interviewed beautifully, told great stories, and the owner loved her. Candidate B was awkward in the interview and spent half the conversation asking sharp questions about the territory, the comp plan, and how the company won deals against bigger competitors. Hire B. The references rated him a nine and explained exactly why. The scorecard outcomes mapped to his actual track record. Eighteen months later he is the top producer.
Common questions about Assess
Why do I keep making bad hires even when interviews go well?
Because the interview measured the interview. Comfort in conversation and confidence in speech are real signals, but they are signals about conversation and speech, not about doing the job. When good interviews keep producing hires who cannot do the work, the fix is to add evidence the interview cannot give you: a scorecard written before the first call, the same questions across every candidate, and a work sample. Gut feel stays in the room as one input. It stops being the whole decision.
What's the difference between a structured interview and a regular one?
A regular interview is a conversation that goes wherever it goes, which makes every candidate's interview different and none of them comparable. A structured interview asks every candidate for the same role the same questions in the same order, and grades the answers against the scorecard. Candidates get compared to each other on the same dimensions instead of to whoever was most charming. It takes the same hour. It produces evidence you can actually debrief on.
Should I be using a scorecard for hiring?
Yes, and it can be one page. Before you interview anyone, write down the three to six outcomes that will define success in the role at the twelve-month mark, each one measurable. Interview questions map to the outcomes, and every debrief grades against them. The scorecard is the difference between "I liked her" and "she has done the two things this role exists to do."
How do I assess for skills I don't have myself?
Borrow the judgment instead of faking it. Have the candidate produce a work sample, then put it in front of someone who has the skill: a peer in your network, an advisor, or your sharpest person in the adjacent seat. Pair that with reference questions specific enough to force a real answer, like how the candidate's work compared to others in the same role. You do not need to be able to do the work to verify the work. You need twenty minutes from someone who can.
How do I tell if a candidate can actually do the job?
Four questions sit underneath every hire: Can they do the work, will they do the work, are they a fit, and do they own their outcomes? "Can they" is a capability question, answered by work samples and structured interviews. "Will they" is a motivation question. "Fit" is about the environment. "Locus of control" is about ownership. Get evidence on all four before offering. Skipping one of them is where most bad hires come from.
Are personality tests worth using for SMB hiring?
They can be, but as one signal among several, not as the decision. A personality test that flags concerns is a prompt to ask better follow-up questions, not a reason to pass on a candidate. Big Corporate, Inc. tends to over-rely on tests because they need defensibility. Small businesses can use the test as a starting point for a real conversation, which is the more useful version.
What is a work sample and how do I create one?
A work sample is a short version of the actual job, done by the candidate as part of the interview process. The format varies by role and there is no universal recipe. A sales role can be tested with a quick roleplay or short presentation during the interview itself. A welder gets a sample weld at the shop. An accountant cannot do a real budget on the spot, so the work sample becomes a structured technical conversation with specific scenarios.
How many interviews should a small business run per candidate?
As few as possible. How you get there is up to you, but when it stretches to two, three, four separate visits or calls, candidates start dropping. Strong candidates have other options and they will not burn six hours of PTO on a process that drags. The better move is to design one substantial visit that gathers everything you need. If two managers will weigh in on the decision, have them interview the candidate together or back to back in the same visit. Optimize the process to respect the candidate's time away from work. Doing this well also signals how you will treat them once they are hired.
What is the single biggest predictor of whether a hire works out?
Locus of control, whether the candidate believes their outcomes are mostly the result of their own actions or mostly the result of things happening to them. Internal-locus candidates outperform external-locus candidates in nearly every SMB role studied. Probe for it in interviews. Ask about a time something went wrong and listen for whether they own a piece of it or hand the whole thing to circumstance.
How we run Assess inside a partnership
In a Fractional Recruiting partnership, the scorecard, the structured interview, and the reference protocol are built per role and run consistently across every candidate. The owner still makes the call. The owner just makes it on better evidence. The next step after assessment is the offer: see Close.
