• 14. What would you do if a team member was consistently exceeding their budget for a project?
  Answer: I would first bring it to their attention and review their cost tracking methods to identify any discrepancies. If the issue persists, I would discuss it with their manager and try to determine the root cause of the budget overruns. Together, we can come up with a plan to ensure the project stays on budget.
• 15. How would you handle a situation where a supplier increases their prices during a long-term contract?
