Interviews are a rather polarising experience. A lot of us raise our game and discover a level of confidence we were previously unaware of, while some succumb to feelings of dread and anxiety; able only to project a fraction of their full capability.
Building a team that gels together is a tricky task which eludes many business leaders and managers. It's relatively easy to recruit and throw together a bunch of high-performing individuals without regard to their different personality types, but this can often lead to internal discord and division later down the line.
Interviews are just as much about asking the right questions as they are about answering them. Not only do they have the obvious benefits of making you look well-prepared and keen but they can also help you take control of the process, thus overcoming nerves.
