Interesting, though perhaps they misinterpreted the question. Some companies seem to have a culture where you never admit failure and perhaps they assumed that was the answer you were looking for?
All of the failed responses weren't just not admitting failure, but directly blaming others. One example was a team lead in charge of a project where they said the developers missed their deadlines and would "whine" about not having enough details to do their job. Someone who didn't have an example of failing to deliver, but had examples of near misses they were able to save would even be good examples. Playing the blame game, though, just doesn't fit.
