They use the STAR process. They ask about a scenario, a task, the action you took and the obtained result. I would suggest to put it in a story like mode where you tell the interviewer little chapters of your professional experience in a succinct fashion

The hiring process was a pretty smooth transition, I had an email sent to me by a recruiter, I replied to the email and the recruiter called me by phone around 11a and set up a phone interview later that day by 4p with the recruiting specialist, she loved our call and passed me on to the next step. Which was an in person panel interview for the next day with the sales manager, the regional sales manager, and the recruiter I had my initial phone interview with, it was the typical STAR interview questions, but I did well, because I was prepared and I know my experience well! They of course loved me, because I had everyone laughing in the interview! The total interview lasted 40 minutes! Was called that same day by 6:30p and was extended an offer! I accepted!
