Welcome to your interview.
The question is on your right: Parse and Validate Student XML. 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.
Can you explain how you would parse and validate an XML code fragment containing student assessment data?
