Welcome to your interview.
The question is on your right: Learning a Technical Product Fast. 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.
Tell me about a time you had to quickly learn a highly technical product or service in order to move a deal forward. How did you get credible fast, and how did that learning help you close the sale?
