Interview with HR Managers on a panel. Questions had many layers to them, it was difficult to cover every point they orginally asked per question. If you missed a part of that they would ask that specific portion again. I recommend to take the opportunity to share your biggest accomplishments in the introduction or when you close, don't count on that being one of the questions they ask and if you don't get it in there on your own you might not be asked. Definately ask questions at the end, at least 2 or 3.
