Welcome to your interview for the Data Scientist role at LendingClub.

The question is on your right: Design an A/B Test for Recommendations. 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. You have three graded attempts to score 7/10 or better.

Only Submit answer is graded - discussion is free practice.

Problem

How would you design an experiment to test whether a new LendingClub loan recommendation feature increases application completion rate?
