Describe the size of teams you have worked with and their composition.

In my team experience, team sizes ranged from small (3-5 people) to medium (10-12 people). Usually, team members had varying levels of experience (junior, middle, senior), including developers, testers, a team lead, and sometimes a product manager. In small teams, roles often overlapped, e.g., a developer might also participate in testing. Larger teams had more specialized roles, which improved code quality.
