A number of factors can fall outside a leader’s control such as the available skill pool in the organization, time constraints, the economic climate. If employees are lethargic and negatively orientated it can create a situation ripe for failure. In answering leadership interview questions that explore how you deal with difficult challenges focus on how you were able to analyze the setback and seek honest feedback to learn from failure. How you used the difficult situation to encourage constructive questioning of policies and practices. Show your ability to be resilient in the face of failure and to constantly work towards improvement.
