FROM READING TO INTERVIEW PRACTICE
Read the PDF independently.
Use your own AI chat to discuss your answer
and practise explaining your reasoning.
Short theory, a visual example and a concrete product problem. The context stays with the question.
Work independently with hints and worked answers. Or attach the PDF and practice file to your own AI chat.
Learn with explanations or check yourself. Discuss one point to improve, then try again. Save a progress card to continue later.
“I’d look at cancellations.”
Lauren’s feedback:
You’ve named what you’d check. Now explain how the result would help answer the case.
