Understand the written interview, Thomas assessments and role-specific conversations before you apply.

GIA is a set of brief aptitude tasks. Thomas’s technical description identifies the five areas below. The practice link offers independent preparation for the category; it does not provide Canonical’s live questions or scoring.
Category practice
The reasoning task uses supplied information to reach conclusions; word meaning tests understanding of vocabulary. Practice identifying the exact relationship or meaning before increasing your pace.

This area involves spotting similarities, differences and inaccuracies quickly. For preparation, use deliberate comparisons and review why you missed a detail.

Explore GIA: perceptual speedCategory practice
Thomas describes basic numerical reasoning and manipulation. Refresh simple calculations and comparisons, then practice maintaining accuracy under a time limit.

This task involves mentally manipulating and comparing shapes. Practice tracking orientation systematically rather than relying on an immediate visual impression.

The employer’s FAQ names Thomas International as its assessment partner. A Thomas case study also documents GIA and PPA use, although its growth figures describe the pandemic period and should not be treated as current hiring statistics.
Canonical’s June 2025 hiring-lead guidance distinguishes graduate or associate roles from vacancies open at multiple seniority levels. It says junior and senior achievements are evaluated in context. Choose the appropriate level and explain your contribution, rather than applying indiscriminately.
The documentation team describes peer discussions, a documentation exercise, a documentation-lead conversation and hiring-manager matching. Its exercise examines user needs, information structure and reasoning; the team explicitly distinguishes it from a basic writing test.
Thomas’s Canonical case study identifies Aptitude/GIA and Behaviour/PPA and describes their use alongside written evaluation and interviews. This is direct vendor evidence, not an inference from an application portal.

Canonical gives 30–45 minutes for GIA and 10 minutes for PPA. It describes GIA as required for applicants, while technical assessment depends on the role. These are assessment durations, not invitation expiry periods.

The FAQ requests an anonymous PDF uploaded through the supplied link. It sets no length requirement. Omit identifying links from this document, while following the original application’s separate instructions.

GIA and PPA reports are available through the dashboard. The FAQ limits resending assessments to platform faults, distinguishing those from device or connection problems.

The reviewed sources do not establish a universal passing percentile. The vendor’s historical observation about interview performance is not a published selection threshold.
Canonical prohibits AI assistance in the actual hiring process. Submit your own written work and give independent responses during assessments and interviews.

Canonical groups its process into assessment, interviews, and offer/onboarding. The personalized candidate dashboard sets out the applicable plan.

The documentation team’s account adds detail about the work being assessed. Treat it as guidance for that discipline, not a guaranteed schedule for software engineering or sales.
Allow for a substantial process, while keeping each submission deadline separate from the overall hiring timeline.
| Cycle | Application dates | Likely assessment window | Evidence |
|---|---|---|---|
| Written assessment invitation | Normally within 14 days | Use the unique link in the invitation | Official source The FAQ specifies a two-week submission period and directs candidates needing extra time to their Hiring Lead. Source: Canonical careers FAQ |
| Application to offer | Vacancy-specific application closing date | Approximately three months on average | Official source Canonical publishes this average across graduate-to-VP hiring; an individual application can take a different amount of time. Source: Canonical hiring process |
Build a compact evidence bank before your invitation arrives. Useful practice means being able to explain your own decisions clearly, not memorizing a model applicant’s story.
Select examples with a clear problem, your contribution, a result and a lesson. For engineering, explain design tradeoffs and failure modes; for commercial work, connect actions to customer or business outcomes.
Practice answering a broad prompt directly, then supporting it with a specific example. Give academic achievements enough context for a reader from a different education system. Remove repetition rather than targeting an arbitrary page count.
Understand each task before trying short timed sets. Record whether mistakes come from misunderstanding, calculation or rushed comparisons; address that cause before repeating a full session.
Choose a past project you can explain from first principles. Revisit alternatives you rejected, how you measured success and what you would change. For documentation work, prepare a rationale for the intended reader and information structure.
Review the requested document format, upload link and deadline before starting. Reserve time to check that every question is addressed and that identifying information has been removed where requested.
Yes. Canonical names Thomas International in its FAQ, and Thomas’s case study identifies GIA and PPA. These are different assessments.
No. Expect written evaluation and interviews as well; technical work depends on the role. Prepare evidence of actual work alongside aptitude practice.
Canonical sets no required length. Answer every question with enough detail to support your point, using the invitation’s submission instructions.
No universal cutoff is established by the reviewed public sources. A practice result cannot guarantee progression in Canonical’s process.
Follow the specific invitation. The documentation team describes an exercise about documentation problems and user needs; it should not be replaced with a generic coding-test preparation plan.
