Situational Questions

• 16. How do you handle a requested feature that conflicts with the project's timeline and budget?
  Answer: In such a situation, I would first assess the feasibility of the requested feature and determine if it aligns with the project's goals. If it does, I would discuss with the stakeholders and develop a plan to incorporate it into the project without significantly impacting the timeline and budget. If it is not feasible, I would explain the reasons to the stakeholders and offer alternative solutions.
