Welcome to your interview.
The question is on your right: Symmetric vs Asymmetric Encryption. 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.
Explain the difference between symmetric and asymmetric encryption and provide an example of when to use each.
