Welcome to your interview.
The question is on your right: Complex Business Rule Example. Take a moment with it first.
Talk your thinking through with me if you like - when you're confident, submit your answer and I'll grade it like a real screen (7/10 or better passes). Discussion and graded submissions share your five interviewer interactions, so spend them well.
Describe the most complex business rule or process you developed. What was the challenge? What was your role? What was the outcome?
