The overall poor wording - odd number(s), bad words and grandeur - support the impression that it's a rage post, rather than a (at least attempted) faithful, balanced, report of the fact.
I have not yet had a chance to read the letter and all commentary, but I hear echos of Max Howell’s “google didn’t hire me because I cannot invert a binary tree”.
It was obviously a rage post; it was obviously his impression of the interview (even though “inverting a binary tree”, being an ill-defined operation, is unlikely what they asked him to do).
And following that affair, my impression was that he wasn’t hired for reasons other than his programming abilities - being a team player (and specifically not being a loose cannon) matters at least as much.

It's literally trying to understand the truth from the messages
