Most "best assessment tools" lists rank every vendor on one scale. Buyers don't work that way: a five-person company hiring its first support agent and a bank hiring two thousand graduates need different products. This guide sorts the main vendors into five categories, gives a pick for each situation, and is upfront about where our own product fits.
Disclosure: Cohesyve publishes this guide and sells a job simulation product. Every vendor is described from its own public positioning as of October 2026. We don't quote competitors' prices because they change; follow the links.
What are the best pre-employment assessment tools in 2026?
| If you are... | Start with | Why |
|---|---|---|
| A small business hiring a few people a year | TestGorilla, Testlify, Cohesyve | Free plan, free trial or free candidates, and self-serve setup |
| Hiring software engineers | HackerRank, Codility, CodeSignal | Coding environments built for technical screens and live interviews |
| An enterprise hiring across many roles and countries | SHL, HireVue, iMocha | Large catalogues, validation research, enterprise integrations |
| Hiring hourly staff at high volume | Harver, HireVue | Automation and scheduling around the assessment |
| Hiring sales or customer-facing staff | Cohesyve, Canditech | Voice role-plays with an AI buyer or customer (Cohesyve), sales and service simulations (Canditech) |
| Short of interview time for good applicants | Cohesyve, Vervoe | Job simulations of the real work; Cohesyve also returns a ranked shortlist |
What types of assessment tools are there?
There are five: skills tests (a library of ready-made tests), technical assessments (coding environments), psychometric tests (reasoning and personality), video interviews (recorded answers to set questions) and job simulations (a slice of the actual job). Most teams need one well-chosen tool plus a structured interview. For definitions and the research behind each type, see what a pre-employment assessment is.
Cohesyve
Putting together a list of tools to try?
Cohesyve takes a job description, finds candidates, reaches out to them and runs an AI job simulation of the real work, then returns a ranked shortlist. Ten candidates free, no card.
Which skills testing platforms are best?
Skills test libraries are the fastest way to start. You combine ready-made tests into one assessment per role.
| Tool | Positioning | Best for | Pricing |
|---|---|---|---|
| TestGorilla | Skills test library plus AI interviews | Small and mid-sized teams that want a free plan | Free plan plus paid plans; check their site |
| Criteria | Aptitude (CCAT), personality, skills and video interviewing | Teams that want validated aptitude tests; free trial | Check their site |
| Testlify | Builds role-specific tests from a job description | Teams hiring across many roles | 7-day free trial; check their site |
| eSkill | Large modular library, custom questions | Operational and frontline roles | Check their site |
| iMocha | Skills and work intelligence for enterprises | Enterprises that also want skills data for internal mobility | Check their site |
Verdict. TestGorilla or Testlify for a quick start, Criteria if aptitude matters (what candidates see on the CCAT), eSkill for frontline roles. The catch with any library is that the same tests go to many employers, so they rarely match your exact role.
Which technical assessment tools are best for developers?
HackerRank, Codility and CodeSignal overlap heavily. All three offer a take-home screen and a live interview environment, and all now pitch around how engineers work with AI tools.
| Tool | Products | Best for |
|---|---|---|
| HackerRank | AI-led screen, pair-programming interviews, screening tests | Engineering teams of any size |
| Codility | Screen, Interview (in VS Code), Skills Intelligence | Teams that also want to map their current engineers' skills |
| CodeSignal | Technical, business and behavioural assessments, AI Interviewer | Teams hiring engineers plus some business roles |
Verdict. Pick on the environment your engineers trust and your ATS. More options: CoderPad, TestDome, Karat, HackerEarth and Coderbyte.
Which psychometric tests do employers use?
| Tool | Measures | Best for |
|---|---|---|
| SHL | Cognitive (Verify), personality (OPQ), situational judgement, simulations | Large organisations, graduate and volume hiring |
| Wonderlic | Cognitive ability, personality, motivation | A simple, well-known screen |
| The Predictive Index | Behavioural and cognitive assessments | Mid-sized companies that also use results for managing people |
| Hogan | Personality for selection and development | Leadership hiring |
| Mercer Mettl | Psychometric, aptitude and coding tests | Enterprise and campus hiring |
Verdict. SHL for global programmes, The Predictive Index for mid-sized teams, Hogan for leadership. Psychometrics tell you who is likely to learn quickly; pair them with a test of the work to see who can do the job on day one.
Which video interview tools are best?
| Tool | Positioning | Best for |
|---|---|---|
| HireVue | AI Interviewer, video, game-based and skills assessments | Enterprise and high-volume hourly hiring |
| Spark Hire | One-way video plus a simple ATS | Small and mid-sized teams |
| VidCruiter | Structured live and recorded interviews, scheduling | High-volume and public-sector hiring |
Verdict. A recorded answer shows how someone communicates, not whether they can do the work. Pair it with a skills test or simulation. See also one-way video interviewing.
Which platforms offer job simulations?
Job simulations give the candidate a realistic piece of the job and assess what they produce. They predict on-the-job performance better than a generic quiz because they test the job itself (why work samples work).
| Tool | What the simulation looks like | Best for |
|---|---|---|
| Cohesyve (our product) | Built from your job description: code to fix, a spreadsheet to analyse, writing, a chat or a spoken call with an AI customer or buyer. Can also source candidates and reach out to them, then returns a ranked shortlist | Teams that want interview time spent only on the strongest candidates, technical or not |
| Vervoe | Spreadsheet, presentation, code, video and text tasks; AI grading trained on your team's grading | Enterprise and high-volume professional hiring |
| Canditech | Simulations for sales, service, technical and operational roles | Sales and customer service hiring |
| Harver | Live chat support simulation plus personality, cognitive and game-based tests | Contact centre, BPO and retail volume |
Verdict. Harver for contact-centre volume, Canditech for sales and service, Cohesyve if you want the assessment built from your own job description and a shortlist at the end. More in our guide to job simulations for hiring.
Why do teams choose Cohesyve?
Most tools on this page start once you already have applicants. Cohesyve covers the whole front of the funnel: you give it a job description, it sources candidates, reaches out to them, puts every applicant through a job simulation of the real work and returns a ranked shortlist. What that looks like in practice:
- Built from your role, not a library. Each simulation is generated from your job description, so a support hire handles a customer and a financial analyst works through a spreadsheet. Formats include coding, spreadsheets, writing, chat simulations and voice role-plays.
- Fewer interviews per hire. Indago Research, a financial research firm, went from 10 to 15 interviews per role to 3 to 4 (case study).
- Fast to start. Blue Ashva Capital had assessments live the day after signing up and cut time to hire by 50% (case study).
- Fits your stack. Connects to 30+ applicant tracking systems, including Greenhouse, Lever, Workday, Ashby and SmartRecruiters, with candidates and results syncing both ways.
- Works for global hiring. Candidates can take it in any of 18 languages, and your report is in English.
- Simple pricing. A subscription from $199 a month on annual billing, sized to your hiring volume, and 10 free candidates to try it on a live role with no credit card (pricing).
Where it is not the right fit: if you only need a single generic aptitude score for thousands of applicants, a psychometric vendor such as SHL or Criteria is the simpler buy. If your engineers want a dedicated live-coding interview environment, HackerRank, Codility or CodeSignal are built for that.
Which tool fits your company size?
| Company size | What matters | Good fits |
|---|---|---|
| Under 50 employees | A free plan or free candidates, self-serve setup | TestGorilla, Testlify, Cohesyve |
| 50 to 500 employees | ATS integration, room for the whole hiring team, skills plus behaviour | Cohesyve, Criteria, The Predictive Index, CodeSignal, Vervoe |
| 500+ employees, many roles | Validation evidence, bias audits, languages, enterprise ATS | SHL, HireVue, iMocha, Mercer Mettl, Hogan |
| Any size, hourly volume | Mobile completion, automation, scheduling | Harver, HireVue, VidCruiter |

How much do pre-employment assessment tools cost?
Vendors price in four ways: credits per candidate, invite allowances plus user seats, a subscription sized to hiring volume, or an annual subscription priced by headcount. Enterprise vendors usually quote. TestGorilla, for example, has a free plan and uses credits per candidate; The Predictive Index sells an annual subscription by headcount. Cohesyve is a subscription sized to annual hiring volume, from $199 a month on annual billing. The pricing guide compares the models and the hidden costs.
How do you choose a pre-employment assessment tool?
Work backwards from the job:
- Decide what predicts success. For most roles that is doing the work, not knowing about it. Building a campaign from a brief says more about a marketer than defining terms.
- Protect the candidate experience. Candidates finish tasks that look like the job and drop out of ones that look arbitrary. Try every assessment yourself before candidates see it.
- Check the practicalities. ATS integration, single sign-on, the pricing model at your volume, and how the vendor checks for adverse impact.
- Pilot on a live role. Run two tools for two weeks on one role with enough applicants, and compare interviews per hire.
The full checklist with RFP questions is in how to choose a pre-employment assessment platform.
Are pre-employment assessments legal?
Yes, when they are job-related and don't screen out protected groups at a disproportionate rate without justification. US guidelines treat a group's selection rate below four-fifths of the highest group's as evidence of adverse impact. New York City's Local Law 144 requires a bias audit before using an automated employment decision tool, and the EU AI Act treats AI used in recruitment as high-risk. Ask every vendor for its adverse-impact evidence, and check your obligations with counsel. This is a summary, not legal advice.
Common questions
What is the most popular pre-employment assessment? No vendor publishes comparable usage figures, so any popularity ranking is a guess.
Can one tool cover every role? SHL, Criteria, Testlify and Cohesyve cover technical and non-technical roles. Engineering teams often still prefer a specialist coding platform.
Do assessments replace interviews? No. They decide who gets interviewed, so interview time goes to the strongest candidates.
How do we know it is working? Track interviews per hire before and after, then compare results with later performance and retention.
