3. Types of Pre-Employment Tests | And Which Ones Resist AI SUMMARY Key Takeaways Six points that cover what most employers need to know about test types in the AI era. TAKEAWAY TAKEAWAY 1. Three families cover most needs Ability tests show how people think. Skills tests show what they can do. Behavior tests show how they tend to act. 2. Design matters more than type The same test type can be easy or hard to game. Timers, random pools and visual items make the difference. TAKEAWAY TAKEAWAY 3. Most resistant Typing, timed attention-to-detail and interactive tasks are the hardest for AI to help with. 4. Least resistant Untimed take-home tasks and personality questionnaires are the easiest for AI to help with. TAKEAWAY TAKEAWAY 5. Mix three to five tests Combine types so each one covers what the others miss. Keep the total under 45 minutes. 6. Finish with a conversation A structured interview confirms that test results belong to the candidate. QUICK ANSWER What are the main types of pre-employment tests? The main types of pre-employment tests are cognitive ability tests, job knowledge and skills tests, language proficiency tests, situational judgment tests, personality and emotional intelligence questionnaires, practical tests such as typing, and work samples. Tests that are timed, randomized and visual or interactive resist AI cheating best. hirevalid.com AI-era hiring needs AI-proof tests. 3
4. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 1 The Main Types at a Glance Most pre-employment tests fall into three families. Knowing the family tells you what a test can and cannot tell you. Ability Skills Behavior How well people think What people can do today How people tend to act Cognitive ability Job knowledge Situational judgment Numerical reasoning Language proficiency Personality Verbal reasoning Typing and accuracy Emotional intelligence Abstract reasoning Work samples Recorded video answers Figure 1. The three families of pre-employment tests. Typical length AI resistance (well designed) Test type Measures Cognitive ability Reasoning and learning speed 10-15 min Medium Job knowledge and skills Specific job skills 10-15 min Medium Language proficiency Reading, grammar, vocabulary 10-15 min Medium Situational judgment Judgment in work scenarios 10-15 min Medium Personality and EQ Typical behavior and preferences 10 min Low Typing and attention to detail Speed and accuracy 5-10 min High Work samples A slice of the real job 15-30 min Medium Recorded video answers Communication and reasoning 10-20 min Medium AI resistance ratings are HireValid's general guidance, not research findings. hirevalid.com AI-era hiring needs AI-proof tests. 4
5. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 2 How to Judge AI Resistance AI resistance is not a fixed property of a test type. It depends on how the test is built and delivered. Three factors decide how easily a candidate can get help from an AI tool during a test. When all three are handled well, even text-based tests become hard to game. Factor Question to ask Strong answer Time Is there enough time to ask a chatbot and copy back the answer? Per-question timers that allow reading time only Format Can the question be copied or photographed and answered by AI? Visual, interactive or audio items Exposure Do all candidates see the same questions, which can then be shared? Large random pools that rotate over time The rating scale used in this guide Rating What it means High Hard to answer with AI help in the time allowed, and outside help tends to leave clear signals Medium AI help is possible but slow or risky when timers, random pools and integrity checks are in place Low AI can help a great deal even with good design. Use with care and confirm in the interview KEY POINT Every rating in this guide assumes the test is well designed and protected. An untimed test with the same questions for everyone is easy to game, whatever its type. A fourth layer: integrity checks Design reduces AI assistance. Integrity checks show when it may still have happened. Tab switches, pasted text and answers faster than reading time are recorded and summarized in an Integrity Score that a person reviews. hirevalid.com AI-era hiring needs AI-proof tests. 5
6. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 3 Cognitive Ability Tests Cognitive ability tests measure how well someone reasons, solves problems and learns. They predict how quickly a new hire gets up to speed. Measures Numerical, verbal and abstract reasoning, often combined into one score Best for Almost any role, especially roles that need fast learning Typical length 10 to 15 minutes Research note Validity of .31 in a 2022 review of hiring research (Sackett and colleagues) AI resistance Medium when well designed How AI can help a candidate Text-based reasoning puzzles and number problems are easy to paste into a chatbot or photograph with a phone. Without timers, a candidate can get correct answers to most of them. How to protect it • Tight per-question timers that allow reading and thinking, but not a chatbot round trip. • Visual and abstract items, such as shape patterns, which are slower to describe to AI. • Large randomized pools, so every candidate sees a different set. EXAMPLE QUESTION (ILLUSTRATIVE) Numerical reasoning 180 boxes are split equally across 4 vans. Each van drops 7 boxes at its first stop. How many boxes are left in each van? Answer: 38. 180 divided by 4 is 45, and 45 minus 7 is 38. TIP Visual, timed cognitive tests resist AI far better than long text puzzles. Ask any vendor what share of items are visual. hirevalid.com AI-era hiring needs AI-proof tests. 6
7. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 4 Job Knowledge and Skills Tests Skills tests check whether a candidate can already do a specific part of the job, such as using Excel, writing SQL or running a digital campaign. Measures Specific, job-ready knowledge and skills Best for Roles that need a known skill from day one Typical length 10 to 15 minutes per skill Examples Excel, Google Workspace, SQL, JavaScript, Python, digital marketing, bookkeeping Research note Job knowledge tests showed validity of .40 in the 2022 review AI resistance Medium when well designed How AI can help a candidate Knowledge questions are often short and factual, which AI tools answer well. A question such as "Which formula totals a column?" takes seconds to look up. How to protect it • Interactive tasks, such as entering a formula in a spreadsheet cell or ordering steps. • Scenario-based questions that use details shown on screen, not general facts. • Timers and random pools, plus screenshot-based questions where a live task is not possible. EXAMPLE QUESTION (ILLUSTRATIVE) Excel basics Cells A1 to A5 hold weekly sales. Which formula returns the highest value? A) =SUM(A1:A5) B) =MAX(A1:A5) C) =TOP(A1:A5) D) =HIGH(A1:A5) Answer: B. An interactive version asks the candidate to type the formula into a live cell. DO THIS Choose skills tests that make candidates do the task, not just recall facts about it. Doing is much harder to outsource than knowing. hirevalid.com AI-era hiring needs AI-proof tests. 7
8. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 5 Language Proficiency Tests Language tests measure how well a candidate reads, understands and uses a language at work, usually English. Measures Reading, grammar, vocabulary and, in some tests, listening Best for Customer-facing, remote and international roles Typical length 10 to 15 minutes Results Often a CEFR-aligned level estimate (A1 to C2). This is an estimate, not an official certificate AI resistance Medium when well designed How AI can help a candidate Grammar and vocabulary questions are easy for AI. Reading passages can be pasted into a chatbot, and written answers can be drafted by AI. How to protect it • Listening items with audio, which cannot be copied as text. • Timed reading questions with passages shown for a limited time. • Short, timed written answers with typing records, rather than long untimed essays. EXAMPLE QUESTION (ILLUSTRATIVE) Grammar in context Choose the correct word: "The report must be submitted ___ Friday." A) until B) by C) since D) for Answer: B. "By" marks a deadline. WATCH OUT Never describe a hiring language test result as an official CEFR certificate or qualification. It is a CEFR-aligned estimate. hirevalid.com AI-era hiring needs AI-proof tests. 8
9. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 6 Situational Judgment Tests Situational judgment tests (SJTs) show candidates realistic work scenarios and ask what they would do. They measure practical judgment. Measures Judgment and priorities in realistic scenarios Best for Customer service, sales, team leads and client-facing roles Typical length 10 to 15 minutes Formats Pick the best response, rank responses, or rate each response AI resistance Medium when well designed How AI can help a candidate A chatbot can usually suggest the most "textbook" answer to a workplace scenario. Single-choice SJT questions are the easiest to answer this way. How to protect it • Ranking and rating formats, which need several judgments per scenario. • Scenarios tied to company context shown on screen, not generic situations. • Timers per scenario and random selection from a large scenario bank. EXAMPLE QUESTION (ILLUSTRATIVE) Customer service scenario A customer says their order arrived damaged. Policy requires a photo before a replacement. Which response is best? A) Ask for a photo, then apologize. B) Apologize, promise to resolve it, and ask for a photo to speed up the replacement. C) Send a replacement without checking. Best answer: B. It shows empathy, follows policy and moves the case forward. TIP Write SJT scenarios around real situations in your business. The more specific the context, the less a generic AI answer helps. hirevalid.com AI-era hiring needs AI-proof tests. 9
10. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 7 Personality and Emotional Intelligence Questionnaires These questionnaires ask candidates about their typical behavior, preferences and how they manage emotions at work. Measures Traits such as conscientiousness, plus workplace emotional awareness Best for Starting interview conversations, team-fit discussions Typical length About 10 minutes Research note Conscientiousness showed validity of .19 in the 2022 review, lower than ability and skills tests AI resistance Low, even when well designed How AI can help a candidate There is no right answer to check, so a chatbot can simply suggest the profile an employer seems to want. Candidates could already present an ideal picture of themselves before AI. AI makes it easier. How to protect it • Use as a conversation starter, not a pass or fail filter. • Prefer scenario-based EQ items over simple self-ratings. • Follow up in the interview with questions about real past situations. EXAMPLE QUESTION (ILLUSTRATIVE) Self-rating item "I like to plan my work in detail before I start." Strongly disagree, Disagree, Neutral, Agree, Strongly agree. There is no correct answer, which is why AI can easily suggest an "ideal" one. WATCH OUT Three different things Do not confuse personality questionnaires with "integrity tests", which ask about honesty at work, or with an Integrity Score, which describes how a test attempt was taken. hirevalid.com AI-era hiring needs AI-proof tests. 10
11. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 8 Typing and Attention-to-Detail Tests Practical tests measure speed and accuracy on tasks such as typing, data entry and spotting errors. Measures Typing speed and accuracy, error spotting, data handling Best for Admin, data entry, customer support, finance and compliance roles Typical length 5 to 10 minutes Device Desktop or laptop for typing tests. Many detail tests also work on mobile AI resistance High when well designed How AI can help a candidate AI offers little help when the task is typing a passage in real time or spotting differences under a tight timer. The main risk is pasting text into a typing test, which can be blocked and detected. How to protect it • Block paste in typing tests and record keystrokes. • Use tight timers on attention-to-detail items. • Randomize passages and records so practice copies do not help. EXAMPLE QUESTION (ILLUSTRATIVE) Attention to detail Are these two records the same or different? Order 70413-B, $1,284.50, Leeds | Order 70413-B, $1,248.50, Leeds Answer: Different. Two digits in the amount are swapped. KEY POINT Practical tests are among the most AI-resistant types available. They are a strong, quick addition to admin and support assessments. hirevalid.com AI-era hiring needs AI-proof tests. 11
12. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 9 Work Samples and Take-Home Tasks Work samples ask candidates to do a small piece of the real job, such as writing a reply, analyzing data or fixing code. Measures Real job performance on a representative task Best for Writing, analysis, marketing and technical roles Typical length 15 to 30 minutes when timed. Take-home tasks often run for hours AI resistance Medium when well designed How AI can help a candidate Untimed take-home tasks are the most exposed format of all. AI can draft code, copy, analysis and slides in minutes. The result shows what AI can do, not the candidate. How to protect it • Run short, timed work samples under test conditions instead of take-home tasks. • Record typing and paste events for written answers. • Discuss the work in the interview. Ask the candidate to explain choices and change something live. EXAMPLE QUESTION (ILLUSTRATIVE) Timed work sample "A customer writes that their delivery is a week late and they want a refund. Reply in under 120 words. You have 8 minutes." Typing and paste records show whether the reply was written in the test. DO THIS If you use a take-home task, treat it as a talking point for the final interview, not as a filter. Or state openly that AI tools are allowed and judge how well they are used. hirevalid.com AI-era hiring needs AI-proof tests. 12
13. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 10 Recorded Video Answers In a one-way video interview, candidates record answers to set questions on their own time. Employers watch the recordings later. Measures Spoken communication, reasoning and presentation Best for Customer-facing and sales roles, high-volume screening Typical length 10 to 20 minutes for 3 to 6 questions AI resistance Medium when well designed How AI can help a candidate Candidates can read AI-written answers from another screen or an on-screen overlay tool. Delivery can look fluent even when the content is not the candidate's own. How to protect it • Show each question only when recording starts, with short thinking time. • Ask follow-ups about specific past experiences, which generic AI answers handle badly. • Confirm in a live conversation before making an offer. EXAMPLE QUESTION (ILLUSTRATIVE) Video question "Tell us about a time you lost a customer and what you changed afterwards." 30 seconds to prepare, 2 minutes to answer. A specific, personal story is hard to fake on the spot. TIP Watch for answers that sound polished but stay generic. Specific names, numbers and details from real experience are hard to fake on the spot. hirevalid.com AI-era hiring needs AI-proof tests. 13
14. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 11 AI Resistance Compared Good design moves almost every test type up the scale. This chart shows how far. Very low Low Medium High Very high Typing speed and accuracy Attention to detail (timed) Interactive tasks (spreadsheet, ordering) Cognitive ability (mixed items) Language proficiency Situational judgment Job knowledge questions Work samples and take-home tasks Recorded video answers Personality and EQ questionnaires Untimed, fixed questions, unprotected Well designed and protected Figure 2. AI resistance by test type, unprotected vs well designed. HireValid's general guidance, not research findings. What the chart shows • Every type improves with timers, random pools, visual items and integrity checks. • Practical and interactive tests start strong and become very hard to game. • Personality questionnaires stay low, because there is no correct answer to protect. KEY POINT The biggest gains come from fixing untimed, fixed-question tests. If you change one thing, add per-question timers and random question pools. hirevalid.com AI-era hiring needs AI-proof tests. 14
15. Types of Pre-Employment Tests | And Which Ones Resist AI CHAPTER 12 Building an AI-Resistant Assessment The strongest assessments mix test types so each one covers the others' gaps. Role Suggested mix Total time Customer Support Agent Customer service SJT, English proficiency, attention to detail, typing 40 min Sales Development Rep Sales aptitude SJT, verbal reasoning, EQ, English proficiency 40 min Office Administrator General cognitive ability, attention to detail, Excel basics, time management 38 min Junior Data Analyst Numerical reasoning, SQL fundamentals, Excel task 35 min Junior Developer General cognitive ability, JavaScript or Python, problem solving 40 min Virtual Assistant General cognitive ability, English proficiency, Google Workspace 35 min Times are illustrative and assume 8 to 15 minutes per test. Five rules for the mix 1. Start with the job. Pick one test for each skill that separates great hires from average ones. 2. Include at least one high-resistance test. Typing, timed detail or an interactive task. 3. Limit low-resistance types. Use personality questionnaires for conversation, not filtering. 4. Stay under 45 minutes. Three to five short tests give most of the insight. 5. End with a structured interview. Ask candidates to explain one or two test answers. DO THIS Review each candidate's Integrity Score next to their results. A high score with a Review suggested band is the result to check first. hirevalid.com AI-era hiring needs AI-proof tests. 15
16. Types of Pre-Employment Tests | And Which Ones Resist AI FAQ Frequently Asked Questions What are the most common types of pre-employment tests?
