Have you participated in projects with integration points to existing code or systems during development?

Yes, in projects, there is often a situation where it is necessary to connect to existing code or systems during development. This can be:

• Integration with an already functioning API or service.
• Extending or modifying existing functionality.
• Working with inherited code, where it is necessary to understand the logic and add new features.

For example, in a Python project, you can connect to an existing module and use its functions:

# Existing module utils.py

def calculate_sum(a, b):
    return a + b

# In new code
from utils import calculate_sum

result = calculate_sum(5, 7)
print(result)  # Will output 12

This approach requires understanding the system architecture, component interactions, and carefulness to avoid disrupting the existing logic.
