"It’s one thing to say that you work well on a team, but another entirely to share an anecdote about how you held a team together during ...a crisis.
Interviewers will ask for anecdotes that demonstrate qualities essential for the job you’re interviewing for."
You can do this by practicing a confident, strong speaking voice and friendly, open body language. While these might come naturally to you..., you might also want to spend time performing them with trusted friends or family or in front of a mirror. Pay special attention to your smile, handshake and stride.
