Welcome to your interview.
The question is on your right: User Research With Limited Resources. 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.
You need to conduct user research for a product redesign, but you have limited time, budget, and access to users. You still need enough insight to make sound design decisions and keep stakeholders confident in the direction.
What is your approach to conducting user research with limited resources?
