The Caliper assessment: what it measures, how long it takes, and how to prepare
The Caliper assessment is a personality questionnaire with a reasoning section attached. Most questions ask which statement is most and least like you; one section has number patterns and shape analogies with right answers. It is untimed and takes about 60 to 75 minutes. In Singapore, candidates met it at Millennium and OCBC. The reasoning section is the part worth practising, using the same question types as a logical reasoning test.
- Two parts: most / least like me statements, then a reasoning section.
- About 60-75 minutes, untimed; a 25-minute version drops the reasoning.
- Reasoning items are number series and shape analogies with right answers.
- Reported at Millennium (2021-2023) and OCBC (2021).
- No pass mark: results are compared with the profile the role needs.
What is in the Caliper assessment
Personality statements
Most items show a set of statements about how you behave. You choose the one most like you and the one least like you. Some items use a rating scale instead. Caliper reports these as a set of personality traits that the employer compares with the job.
The reasoning section
A shorter block of items has right answers: number patterns (what comes next in a series) and shape analogies (A is to B as C is to which shape). Candidates at Millennium described it as pattern and number questions "like a Mensa book", and one said it was harder than the TFIP aptitude test.
What candidates in Singapore reported
| Employer | Year | What candidates reported |
|---|---|---|
| Millennium | 2021-2023 | Sent before interviews for software, data and AI roles. Part one most / least like me, part two pattern and number reasoning. About 40 to 75 minutes, no strict time limit |
| OCBC | 2021 | Data analytics role. A Caliper assessment before or alongside the interview, described as more cognitive than behavioural |
| IBF (TFIP) | 2021 | Some applicants got a Caliper invitation from IBF that did not name an employer |
How to prepare for the Caliper assessment
- Practise number series: find the rule (add, multiply, alternate) before you look at the options.
- Practise shape analogies: name the change from the first shape to the second, then apply it.
- For the statements, pick what you actually do at work or in projects, and stay consistent.
- Block 75 minutes in one sitting; the test can be long.

Frequently asked questions
What is the Caliper assessment?
The Caliper Profile is a workplace personality and reasoning assessment, now published by Talogy. Most items ask you to pick the statement most like you and the one least like you; a smaller set uses rating scales; and a reasoning section uses number patterns and shape analogies that have right answers.
How long does the Caliper assessment take?
Caliper says about 60 minutes and that it is not timed; Talogy says most people finish in 60 to 75 minutes. Candidates in Singapore reported between about 40 and 75 minutes.
Can you fail the Caliper test?
There is no pass or fail. Results are compared with the profile the employer wants for the role. The reasoning section does have right and wrong answers, so it is the part worth practising.
Which employers in Singapore use Caliper?
Candidates reported the Caliper assessment at Millennium between 2021 and 2023 for software, data and AI roles, and at OCBC for a data analytics role in 2021.
Is there a shorter version of Caliper?
Yes. Caliper's FAQ describes an abbreviated form of about 25 minutes without the reasoning section, recommended for entry-level roles. Your invitation or the time estimate on the first screen tells you which one you have.
Note on accuracy: the test providers named in this guide reflect candidate reports and publicly available information as of 2026, and are provided for preparation guidance only. Employers do not usually publish which assessment provider they use, and these relationships change over time — Millennium or OCBC may switch providers, run different tests for different roles, regions or intakes, or use a provider not listed here. Nothing on this page is confirmed or endorsed by Millennium or OCBC or any test publisher, and it should not be relied on as a definitive statement of Millennium or OCBC’s current process. Always confirm the exact test and provider from your official invitation email before you prepare.
