Have you ever had to perform tasks intended for other teams or specialists?

Yes, it is common in practice to perform tasks that formally belong to other teams or specialists. This can happen due to limited resources, the need for quick problem resolution, or to better understand related fields.

For example, a developer might help with infrastructure setup or write tests if the QA team is busy. It is important to maintain communication and not to go beyond one's competencies without approval to avoid conflicts and to maintain work quality.
