Welcome to your interview.
The question is on your right: Sample Size for Low-Frequency Events. 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 estimate the sample size needed for an experiment on a low-frequency workforce event at UKG?
