I was declined at interview #5, after passing the previous four. Not sure how much that question played a role. It was also the weakest of my technical interviews. I was surprised to get hit with more programming questions after having passed so many other technical interviews with them.
After 5 interviews which dragged out for almost two months that was super disappointing though. It was probably the last interview I needed to pass. It's like being knocked out of the race with a blue shell in the last 20 seconds in Mario Kart.
