Walmart Global Tech Procurement Analyst interview questions

Got a call from HR for the role, it matched my current role so i applied. first round was manegerial round and the interviewer was impressed, second was senior manager lever level, i answere most of the question but got stuck in ac ase based question, were the interviewer asked for how did you prepared supplier scorecard and a savings based question. third round was with another manager who was interviewing for a different role there, i answered the question but the interviewer was looking someone with contract management experience
