Welcome to your interview.
The question is on your right: Overfitting With Limited Market Data. 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.
Explain the concept of overfitting and how you mitigate it when working with limited historical market data at Allianz.
