An interim employee is engaged for a fixed period of time and takes accountability and responsibility, not just providing recommendations. As an interim, you are expected to challenge existing ways of thinking, have an objective agenda to add business value, and help the company achieve its goals and raise performance. To be successful, you must choose the right role for your skills and experience, understand what success will look like, find quick wins, listen to others, ask questions, add value everywhere possible, and know when your work is complete.
