Kenexa Prove It vs TestGorilla: Skills-Plus-Cognitive, Two Libraries
Kenexa Prove It and TestGorilla are not single cognitive tests. They are assessment platforms that let employers build a custom test battery from a library of modules. A candidate might face Excel plus logical reasoning plus typing. Another might face Python fundamentals plus numerical reasoning. Because both platforms pick from large libraries, no two candidates see identical test batteries. This makes prep strategy different from prepping a fixed-format cognitive test: you have to identify which modules your specific employer selected before you can prep effectively.

Format: two module libraries, two audiences
Kenexa Prove It was built pre-2012 as a skills testing platform for enterprise clients. IBM acquired it and integrated it into Kenexa Talent Suite. Its library covers roughly 1,000 modules: cognitive ability tests (numerical, verbal, logical), office skills (Excel proficiency with versions ranging from basic to advanced, Word, PowerPoint), typing tests (accuracy and speed), language proficiency, customer service scenarios, and industry-specific skills. Employers typically combine 2 to 4 modules into a 60-minute battery.
TestGorilla is a modern replacement. Its library is smaller (~300 modules) but designed for 2020s hiring needs: software and coding modules with live execution, work-sample simulations, situational judgment tests, behavioral and personality modules, and cognitive ability tests. TestGorilla offers stronger technical assessment modules (Python, JavaScript, SQL, DevOps) than Kenexa, and weaker legacy office-skills modules (Excel depth is less than Kenexa).
The practical implication: if you are interviewing at an enterprise with legacy hiring infrastructure (large bank, Fortune 500 operations function), Kenexa Prove It is likely your platform. If you are interviewing at a modern tech-adjacent company or a mid-market firm that modernized its hiring stack post-2018, TestGorilla is more likely.
Timing varies by module combination
Kenexa sessions typically run 60 minutes, but composition varies. A common finance employer battery might be 30 minutes of Excel proficiency (Advanced level), 15 minutes of numerical reasoning, and 15 minutes of logical reasoning. A retail operations employer battery might be 20 minutes of typing, 20 minutes of customer service scenarios, and 20 minutes of cognitive ability. Each module has its own time budget.
TestGorilla sessions range from 30 to 60 minutes depending on module count. A typical TestGorilla battery for a software role might be 20 minutes cognitive ability, 30 minutes coding exercise, and 10 minutes personality assessment. A TestGorilla battery for a sales role might be 15 minutes cognitive, 15 minutes situational judgment, 15 minutes DISC personality.
The shared pattern: both platforms bundle cognitive testing with role-specific skill testing. This means prep has to be dual-track. You have to prep the cognitive component (which transfers across employers) and the specific skill component (which does not).
Module comparison by category
Similar categories, different depth and quality.
Cognitive ability modules
Kenexa: numerical, verbal, logical reasoning modules that look similar to SHL. Logical reasoning has a reputation for being harder than the verbal and numerical modules. TestGorilla: problem-solving, critical thinking, numerical reasoning modules. TestGorilla's cognitive modules are modern and well-calibrated but slightly less demanding than Kenexa's logical reasoning.
Office and productivity modules
Kenexa: deep Excel modules ranging from basic (VLOOKUP, simple formulas) to expert (VBA, array formulas, complex pivots). This is Kenexa's strongest category. TestGorilla: Excel modules exist but lack Kenexa's depth at the advanced tier. TestGorilla covers Excel basics well but does not probe expert-level Excel as thoroughly.
Coding and technical modules
TestGorilla has stronger technical assessment: Python, JavaScript, SQL, Java, React, Node.js, DevOps, cloud basics. Live code execution with test cases makes TestGorilla technical modules closer to HackerRank in feel. Kenexa technical modules exist but are older and more multiple-choice-heavy.
Behavioral and personality modules
TestGorilla: DISC personality, Enneagram, Big Five, culture-add assessments. Modern and well-integrated. Kenexa: older personality assessments often bundled with customer service scenarios. Kenexa personality modules have not been refreshed as aggressively as TestGorilla's.
Which is harder
Difficulty depends heavily on which modules the employer selected. Kenexa's advanced Excel modules are notoriously difficult and can consume significant prep time if you are not already comfortable with expert-level Excel operations. TestGorilla's technical coding modules are harder than Kenexa's technical modules at the upper end because the live code execution format reveals real ability (you cannot brute-force multiple choice).
For pure cognitive comparison, Kenexa logical reasoning is harder than TestGorilla's equivalent. Kenexa logical involves more formal deductive and inductive items with less time budget. TestGorilla cognitive is calibrated slightly easier at the same percentile cutoff, which can compensate: hitting the 80th percentile on Kenexa logical is typically harder than hitting the 80th percentile on TestGorilla problem-solving.
The interaction effect: Kenexa Prove It batteries that combine advanced Excel plus logical reasoning feel harder than any TestGorilla battery because the Excel module alone drains time and attention. TestGorilla batteries that combine live coding plus cognitive feel harder at the top end because elite-level coding cannot be faked.
How scores are reported
Kenexa Prove It reports per-module percentiles against the Kenexa norm group. Employers set cutoffs per module. A typical finance role at a bank might require 80th percentile on numerical, 70th on verbal, and 'proficient' level (~60th percentile) on Advanced Excel. Candidates failing any single cutoff are often removed from the pipeline regardless of other module performance.
TestGorilla reports per-module percentiles plus a composite percentile across all modules. The composite scoring is TestGorilla's key differentiator: employers can set an overall cutoff (for example, 'top 25 percent') rather than per-module cutoffs, which sometimes allows compensation across modules. In practice, most TestGorilla employers still set per-module floor thresholds.
Both platforms report sub-skill breakdowns within modules. Kenexa Excel shows detailed scores on formulas, formatting, and pivot tables separately. TestGorilla coding modules show code efficiency, test case pass rate, and coding style separately. Employers read these sub-scores for role-specific fit.
Who uses each and why
Kenexa Prove It runs inside IBM's Kenexa Talent Suite, which means it ships with large-enterprise HR systems. IBM uses it internally. Walmart, Citigroup, P&G, Bank of America, American Express, and many Fortune 500 legacy operations use Kenexa. Kenexa is strongest when the employer needs deep skills testing for office and operations roles (Excel-heavy analyst roles, customer service operations, retail management).
TestGorilla targets modern mid-market and growth-stage companies. PepsiCo (some divisions), H&M, Bain (for some entry-level hiring), Revolut, Sony, and hundreds of Series A through Series D tech companies use it. TestGorilla is strongest when the employer needs technical assessment quality (live coding, SQL, design portfolios) alongside cognitive screening.
How prep actually differs
For Kenexa Prove It, the first step is always identifying which modules your employer has chosen. Email the recruiter or read the invitation carefully. Typical Kenexa batteries include 'cognitive ability (numerical, verbal, logical)' plus one or two skill modules. Once you know the composition, prep the skill module first because it has the steepest learning curve. Advanced Excel preparation from scratch can take 2 to 3 weeks. Logical reasoning preparation takes 5 to 7 days. Numerical reasoning preparation takes 5 to 7 days.
For TestGorilla, the same module-identification step applies. Typical TestGorilla batteries for tech roles include cognitive ability plus a technical module (Python, JavaScript, SQL). Typical TestGorilla batteries for non-tech roles include cognitive ability plus DISC personality plus situational judgment. For technical modules, practice on the relevant platform (LeetCode for coding, SQLZoo for SQL) because TestGorilla's question style mirrors industry-standard coding challenges.
Shared prep: cognitive ability prep. Both platforms use similar cognitive ability testing, and drilling numerical reasoning (percentages, ratios, chart reading), verbal reasoning (short passages with inference questions), and logical reasoning (syllogisms, deduction) helps on both platforms. Spend at least 50 percent of your prep time on the cognitive component because it is the most transferable and most commonly used module.
Order of prep if uncertain which platform: prep Kenexa first. Its logical reasoning module is harder and its Advanced Excel is deeper. Skills built for Kenexa transfer smoothly to TestGorilla. The reverse is less true because TestGorilla Excel prep does not reach Kenexa Advanced Excel depth.
Which one you should actually prep for
Check the invitation platform. Kenexa invites come from proveit.com or IBM Kenexa domains. TestGorilla invites come from testgorilla.com. This is the fastest tell.
If the employer is a large legacy enterprise (Fortune 500 bank, operations-heavy retailer, American Express-tier card issuer), Kenexa is most likely. If the employer is a mid-market or growth-stage tech-adjacent company, TestGorilla is most likely.
Most important prep step: figure out which modules your specific employer chose before investing prep time. Kenexa and TestGorilla both offer so many modules that generic 'prep for the platform' prep is inefficient. Invest 2 hours in clarifying module composition with the recruiter, and save 10 hours of wasted prep.
