Welcome to your interview.
The question is on your right: Improving Homework Retention. 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.
If you were tasked with improving the retention rate of Chegg's homework help service, where would you start your generative research?
