Welcome to your interview.
The question is on your right: Prioritizing One Process Change. 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.
How would you prioritize operational improvements when you can only ship one process change this quarter at Unity Technologies?
