Welcome to your interview.
The question is on your right: Email Campaign KPI Selection. 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 key performance indicators (KPIs) would you track to measure the success of an email marketing campaign targeting existing customers for a pre-approved credit card at Santander?
