Test Rond Carré is a playful online personality-test brand created by Mathilde Le Garzic. Its central offering is a free questionnaire that sorts participants into “round” or “square” profiles, using humorous stereotypes about habits, organization, punctuality, and everyday quirks. The site presents the test as a lighthearted way to reflect on personal tendencies and discuss them with friends, not as a scientific or psychological diagnosis.

No account is required, and most people can complete the questionnaire in a few minutes. Participants are encouraged to answer spontaneously and are reminded that neither profile is better or worse than the other. The brand also offers a Black Cat or Golden Retriever test, inviting visitors to pair their shape-based result with an animal personality type.

Users can share their results with others, and the site provides frequently asked questions, privacy and legal information, and contact options through Instagram. Commercial, advertising, or professional use of the test, its name, or its content requires permission from its creator
