Here, the interview panel wants to know how you respond to critical challenges and deal with conflicting situations in a project. It would be best if you did not refer to examples where you had to manage tough team members or lack of support from management. As a project manager, you should be smart enough to handle such occurrences. Instead, focus on external factors like a situation where the project was unexpectedly called off, or funding was reduced in the middle of an extensive project. Also, you should explain how you tackled the challenges and managed the team during tough situations.
