Have you participated in working on an already launched and functioning project?

Yes, participating in an already launched and functioning project is a common practice. Such experience includes:

• Understanding existing code and architecture.
• Making changes and fixing bugs without disrupting current functionality.
• Working with documentation and communicating with the team.
• Optimizing and adding new features within the framework of the existing project.

This helps develop skills in supporting and scaling applications, as well as learning to work with real business requirements.
