Welcome to your interview.
The question is on your right: Postman Environment Variables and Tokens. 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.
How do you manage environment variables, global variables, and authorization tokens dynamically across collections in Postman?
