The Plum Discovery Survey is an untimed, five-section assessment that Plum says takes about 25 minutes: forced-choice personality rankings, two short puzzle sections and a set of workplace scenarios. You get your own Plum Profile at the end, and you do not need to retake it for each new application. This page covers what the Plum assessment is, its format and timings, how it is scored, the rules to know before you start, how to prepare and a practice plan.
What the Plum assessment is
Plum is a Canadian assessment company based in Kitchener, Ontario. The Discovery Survey measures 12 traits, ten based on the Big Five personality model plus two cognitive ones, problem solving and social intelligence, and combines them into ten Plum Talents such as the ability to adapt, innovate or communicate. Employers define what a role needs through a short Match Criteria Survey completed by people who know the job, and your profile is matched against the role's top five Talents.
Phenom, an HR software company, announced its acquisition of Plum on April 28, 2026, alongside an earlier deal for the cognitive-test provider Be Applied. Plum's site carries the acquisition notice, but the Discovery Survey itself was unchanged when checked in November 2026.
Format and timings
| Part | What it involves | Time and questions |
|---|---|---|
| Section 1: personality | Choose the statements most and least like you | Untimed |
| Section 2: problem solving | Select the missing piece in a sequence of puzzles | Untimed |
| Section 3: personality | Choose the adjectives most and least like you | Untimed |
| Section 4: problem solving | A second series of puzzles of all difficulty levels | Untimed |
| Section 5: social intelligence | Workplace situations: choose the most and least effective responses | Untimed |
Total: about 25 minutes, according to Plum; the survey is untimed and you can pause and finish over several sessions.
How it is scored
- Your answers are compared with Plum's database, so scores reflect your performance relative to a wider population.
- The puzzles deliberately include very hard items to spread scores out; finding some difficult is expected.
- Fit is role-specific: Plum notes that a person who is not a strong match for one role can be a strong match for another with the same results.
- Plum says time taken is not recorded and has no effect on results.
Rules to know before you start
- You can exit at any time and continue later; answers are saved, though employers may set a deadline.
- At the end you can review your answers, but reviewing takes you back to the start and through every question.
- Use the survey's own back button, not the browser's.
- No calculator, speaker or microphone is needed. The survey works on phones, but Plum recommends a larger screen such as a laptop, with Chrome as the preferred browser.
- You can retake the survey one year after your last attempt.
How to prepare
- Set your preferred language before you begin.
- On the forced-choice sections, pick what you would genuinely prioritize when time or energy is limited, which is what Plum says it is measuring.
- Take your time on the puzzles; speed earns nothing here.
- In section 5, judge each response by how effective it would be for the people involved, not by how it sounds.
- Only use the review option if you need it, since it restarts you at the first question.
A practice plan
- Day 1: read the invitation for which questionnaires and tests are included and how long each takes.
- Day 2: read the publisher's own candidate guide and sample items so the response formats are familiar.
- Day 3: write down three recent situations at work or study and what you actually did, so your answers come from one consistent picture of yourself.
- Day 4: if a reasoning part is included, do a short set of pattern, number-series or shape puzzles.
- Day 5: take it in one quiet sitting, early in the deadline window, and make sure you submit.

On the day, and the mistakes to avoid
- Block the full time the invitation states, plus fifteen minutes, in a quiet room.
- Use a laptop or desktop with a current browser, even if the platform also works on a phone.
- Answer as you are at work now, not as you hope to be or as you guess the employer wants.
- Read each statement once and go with your first honest reading; overthinking produces inconsistent patterns.
- Expect to answer every item on a page before you can move on.
- Stay until the final submit or confirmation screen before you close the window.
Mistakes that cost candidates:
- Answering as an imagined ideal candidate, which forced-choice formats and consistency checks are built to expose.
- Spreading the questionnaire over several days and moods, which makes answers less consistent.
- Rushing the reasoning puzzles because 'it is only a personality test', when they are the items with right answers.
- Reading a poor fit for one role as failure; the same profile can match a different role well.
- Forgetting that the interview may probe the extremes in your report.
What happens after the Plum assessment
The employer usually reads your report alongside your résumé and interviews, and many use it to pick interview questions about the areas where your profile and the role differ. Prepare one short example for your strongest work-style tendency and one for the habit you manage most carefully. For the next stage, see our guide to personality tests and AI help.
Where CoPilot Interview fits
Online assessments are tests you take on your own: outside help is not allowed, and proctoring settings can flag other apps, tab switches or a second voice. Practice beforehand instead. CoPilot Interview is an AI interview assistant; its free AI mock interview prepares you for the interviews that follow the assessment, with questions built from your résumé and the job description and each spoken answer scored out of ten. The free plan gives 15 minutes a day of live help in sessions of up to 15 minutes, with AI mock interviews included. Read the invitation carefully and follow your employer's rules.

Frequently asked questions
How long does the Plum assessment take?
About 25 minutes, according to Plum. It is untimed, so some people take longer.
Is the Plum Discovery Survey timed?
No. Plum says it does not record how long you take and that time has no effect on your results.
Can I retake the Plum assessment?
You can retake it one year after your last attempt. You do not need to redo it for each new application.
Is Plum still running after the Phenom deal?
Yes. Phenom announced it had acquired Plum on April 28, 2026, and Plum's help centre and Discovery Survey were still running in November 2026.
Can I use AI tools during the Plum assessment?
No, unless the instructions explicitly allow it. Assessments are meant to be taken on your own, and proctoring settings can flag other apps, tab switches or pasted code. Use AI tools to practice beforehand, and follow your employer's rules.
