Welcome to your interview.
The question is on your right: Choosing Between Fast and Stable Libraries. 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 had to choose between a library that is fast but less maintained, and one that is slower but stable, what is your decision-making process?
