Welcome to your interview.
The question is on your right: Experiment With Novelty Effects. 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 design an experiment to test a new search ranking algorithm at Glean (CA), and how do you account for novelty effects?
