One effective answer could be:
Yes, I have dealt with challenging situations in my previous roles. For example, I was working on a project where a team member had fallen behind schedule and it was putting the entire project at risk. I took initiative and worked with that team member to understand their challenges and came up with a plan to get them back on track. I also updated the project manager with regular progress reports, and as a result, the project was completed on time and received positive feedback. This experience taught me the importance of effective communication and teamwork in handling difficult situations.
