Are skills assessments better than interviews?

For well-defined task work, a representative work sample is among the strongest predictors available and generally outperforms an interview. For roles where the predictive competencies are interpersonal or judgement-based, a structured interview has more to work with. The question is which describes your role.

Do skills tests hurt completion rates?

They can, and the effect scales with task length. In professional pipelines the trade is usually acceptable. In frontline volume pipelines a long task depresses completion sharply, and hardest among candidates with the least time.

Can you use both a skills test and an AI interview?

Yes, and for mixed roles it is often right. Put the harder floor first and apply the second instrument to the shortlist rather than running both on every applicant, and score both against one weighted rubric.

Both avoid the CV sift, which is the largest single fairness improvement either offers. Work samples reward current capability over credentials; structured interviews reward evidence over impression. Whichever you use, monitor adverse impact per requisition — format alone does not settle fairness.

Vervoe compared: when a work sample beats an interview, and when it doesn’t

Work samples are among the best-evidenced selection methods available. If your role is well-defined task work, a task is a better predictor than a conversation about the task — and you should probably not be reading an interview vendor’s comparison page to decide that.

Key takeaways

Vervoe is assessment-first: candidates complete role-specific tasks or challenges and AI grades the output.
Work samples predict well where the job is definable as a task and the task can be simulated honestly.
They predict less well where the competencies are interpersonal, contextual or unfold over time.
Task assessments ask more of the candidate up front, which affects completion in high-volume frontline pipelines.
Combining them — task for capability, interview for the interpersonal competencies — is often the right answer for mixed roles.

What Vervoe does, and what it is good at

Vervoe leads with skills assessment rather than interviewing. Candidates complete role-specific tasks, coding challenges or written exercises, and Vervoe’s AI grades the results, with anti-cheating tooling and AI-graded scoring.

The underlying method has strong support. Asking someone to do a representative sample of the work is one of the better-evidenced approaches in selection research, and it has an obvious face-validity advantage: candidates generally accept that being asked to do the job is a fair way to be assessed for it.

Excellent for technical and craft roles where output is the point and can be graded objectively.
Strong for roles where a portfolio or CV overstates or understates capability — the task settles it.
Useful for career changers, who can demonstrate current capability rather than relevant history.
Good candidate acceptance where the task genuinely resembles the work.

Where task-based assessment strains

Interpersonal competencies

A written exercise cannot show you how someone speaks to a frightened patient, de-escalates an angry guest, or stays warm at the end of a ten-hour duty. Those are the predictive competencies for a large share of the roles Australia hires at volume — care, hospitality, retail, cabin crew, contact centre — and a task-based assessment has little to work with there.

Completion at frontline volume

A meaningful task asks for meaningful effort. For a professional or technical candidate, that is a reasonable trade. For a frontline pipeline where the applicant is applying to six venues on a phone during a break, a substantial task depresses completion sharply — and depresses it hardest among the people with the least time, which is not the selection effect you want.

Simulation honesty

A task only predicts to the extent it resembles the work. Where a role is mostly judgement, prioritisation under interruption, or knowing when to escalate, the simulation gets thin fast — and a thin simulation graded confidently is worse than an interview, because the number looks objective.

Side by side

	Work-sample assessment	Structured AI interview
Measures	Demonstrated capability on a representative task	Behavioural evidence across competencies, probed
Strongest for	Technical, craft and definable task work	Interpersonal, judgement and composure competencies
Candidate effort	Higher — a real task takes real time	Moderate — a conversation on their own schedule
Frontline volume completion	Lower, as task length rises	Higher, and modality is the candidate’s choice
Evidence artefact	The graded output	Verbatim, timestamped citations per competency, or an abstention
Career changers	Strong — current capability over history	Strong if situational questions are used rather than behavioural only
Combining	Task first, interview the shortlist	Interview first, task the shortlist

The combination most mixed roles want

For roles that are part task and part people — a senior barista who also runs a shift, a nurse who also coordinates a ward, a developer who also handles customer escalations — the honest answer is that neither instrument alone covers it.

01Decide which competency is the harder floor to clear. If a candidate who cannot do the task is unhireable regardless, put the task first and interview the survivors.
02If the task is learnable in weeks but the interpersonal competencies are not, interview everyone first and task the shortlist.
03Do not run both on every applicant at volume. The combined candidate effort will cost you more strong candidates than the extra signal is worth.
04Score both against one weighted rubric so the outputs are comparable rather than two separate opinions.
