When I was an engineer at Amazon, we all just made up our own questions, or passed fun ones around the office. I assume the Bar Raisers probably had an actual rubric, but the rest of us didn't (and we all had interviewing quotas to meet)
I left a while back, but folks still there tell me not much has changed (except they do a lot less hiring these days, so quotas aren't as big a part of the promo package)
