Capability Interview means a big change is ahead in the way that interviews are conducted. Instead of being asked and probed on single examples in a straightford way you way find the probing a lot deeper. Prepare for this by reviewing your experience to date in a holistic way – taking into consideration areas where you have shown potential or special interest but have not been given the opportunity to develop. A coaching relationship will allow you to see yourself in a realistic and professional light and perform at your best in Capability Interviews.
