Group dynamics and selection tests: how to prepare

Group dynamics and selection tests are used to observe how you communicate, work in a team, and solve problems. To do well, understand the purpose of the activity, take part without dominating the conversation, and prepare in advance for Portuguese, logical reasoning, technical knowledge, and behavioral profile tests. The law also protects you from discriminatory questions and requirements at this stage.

How group dynamics work

In general, the recruiter brings the candidates together, proposes a topic or a problem, and observes each person's behavior. There is usually no right answer.

• Debate on a topic or business case.
• Solving a problem as a team, within a limited time.
• Simulation of a day-to-day situation of the job.
• Individual presentation followed by questions.

How to behave

• Listen carefully and refer back to what others said before giving your opinion.
• Speak objectively, without interrupting and without monopolizing the time.
• Help the group reach a conclusion, even if your idea does not win.
• Mind your posture: look at people, keep a calm tone of voice, and avoid personal criticism.
• If the group loses its way, propose a division of tasks or a summary.

Do not try to stand out at all costs. Observers usually value collaboration, clarity, and respect.

Tests you may encounter

1. Portuguese and writing: review agreement and punctuation, and write short, clear texts.
2. Logical reasoning and basic math: practice percentages, rule of three, and reading charts.
3. Technical knowledge for the role, such as Excel, customer service, or administrative routines.
4. Profile tests: there is no right answer, so answer honestly and consistently.
5. Case study or practical task: read the entire prompt and organize your reasoning before answering.

To practice, use past tests when the company publishes them, free practice tests, and the open courses mentioned in Mudança de carreira: como começar do zero.

Your rights during the selection process

The Consolidação das Leis do Trabalho (CLT, Brazilian Labor Code) prohibits, among other practices, advertising a job with reference to sex, age, color, or family status, except when the nature of the activity requires it (art. 373-A). It is also prohibited to require a pregnancy or sterility certificate or test at hiring or for continued employment. Lei 9.029/1995 (Law 9,029/1995) prohibits discriminatory practices with regard to access to an employment relationship.

• Questions about pregnancy, plans to have children, or marital status unrelated to the role may be discriminatory.
• Keep the ads, messages, and emails from the selection process, which serve as evidence.
• In case of discrimination, contact the Ministério Público do Trabalho (Labor Prosecution Office) or the Justiça do Trabalho (Labor Court). See Dispensa discriminatória: quando a demissão é ilegal.
