Welcome to your interview.
The question is on your right: A/B Test Significance With Small Samples. 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.
What statistical methods do you use to ensure an A/B test has reached statistical significance, especially when sample sizes are small in newer corridors at Remitly?
