What Is the Plum Assessment? The Discovery Survey Explained
The Plum assessment (Discovery Survey) is an untimed 25-minute hiring screen of personality, problem solving, and social intelligence. What to expect.

The Plum assessment, formally the Plum Discovery Survey, is an untimed online hiring screen that takes about 25 minutes and measures three things: personality, problem-solving ability, and social intelligence. It reports them as ten "Talents," recurring patterns of thought and behavior that employers match against job profiles. Built by the Canadian company Plum and acquired by the HR-tech firm Phenom in 2026, it is one of the most common screens candidates meet in early hiring. This article explains the five sections, how scoring works, and how a Talent profile differs from an intelligence test.
The five sections of the Discovery Survey
Plum's own candidate documentation describes five sections in a fixed pattern:
• Sections 1 and 3, personality: Forced-choice items: you pick the statements or adjectives that are "most like you" and "least like you." These map onto the Five-Factor Model, the "Big Five" framework that dominates modern personality science.
• Sections 2 and 4, problem solving: Short puzzle series in which you select the missing piece in a visual sequence, the classic matrix-reasoning format used in nonverbal cognitive tests.
• Section 5, social intelligence: Workplace scenarios where you choose the most effective and least effective responses, a situational judgment test.
The survey is untimed, can be paused and resumed across sessions, and lets you review answers before submitting. Plum does not record how long you take, and speed has no effect on results. On completion you immediately receive a Plum Profile describing your Talents and the work that energizes or drains you.
What Plum scores actually represent
Under the hood, Plum combines twelve trait measures: ten personality traits from the Big Five plus two cognitive facets, problem solving and social intelligence, into competency scores computed by an algorithm its industrial-organizational psychologists built on established research traditions (forced-choice personality measurement, matrix reasoning, and situational judgment testing). The output is a match profile, not a ranking on a cognitive scale. Press coverage reports Scotiabank, Whirlpool, Hyundai Capital, and Bloomberg among its enterprise users, and Phenom, which acquired Plum in spring 2026, says candidate profiles are mapped against more than 40,000 real-world jobs.
Is the Plum assessment an IQ test?
No. Only two of its five sections measure cognitive ability at all, and the result is a set of Talents, not a score you can place on a norm table. That design is deliberate: Plum sits in the personality-plus-fit tradition of hiring screens, closer to a structured personality test than a skills test, while tools like the Predictive Index Cognitive Assessment sit on the ability side. Whether such screens belong in hiring at all is a live debate; our guide to IQ tests in hiring covers the evidence. If what you actually want is a measured cognitive profile, the Reasoning and Intelligence Online Test from RIOT IQ measures six abilities with real norms, and you can take a free IQ test to see your own numbers.
Frequently asked questions
How long does the Plum assessment take?
About 25 minutes. It is untimed, pausable, and your answers save between sessions.
Is the Plum Discovery Survey timed?
No. Plum keeps no record of how long you take, and time has no impact on your results.
Are there right and wrong answers on the Plum assessment?
The puzzle sections have correct answers. The personality and social-intelligence sections are forced-choice preference items, where consistency matters more than any single "right" pick.
Who owns Plum now?
Phenom, which acquired the company in spring 2026. Plum was founded in 2012 in Canada's Kitchener-Waterloo region by CEO Caitlin MacGregor.
Can you fail the Plum assessment?
There is no published pass mark. Employers compare your Talent profile to a role profile, and cutoffs are theirs, not Plum's.
