A time when you used science to make a decision - typical competency based stuff. They really want concrete DETAILED examples of the STAR type questions but also how it impacted you and the business. They are all about how you made an IMPACT and challenged and motivated colleagues. I didn't get an offer but I was very impressed with the fact that they provided very detailed feedback and critique which I found very useful. Most companies don't even bother and this says a lot about AZ. This company has pulled through some very tough times recently and I really wish them all the best.
