Would be funny if the interviewer wrote the exact same blog post; "I had the worst candidate interview today, I asked him a simple ice-breaker question before getting into more technical stuff, and he just went off about his family and relationships for an hour; weirdest interview I ever gave."

The description of the interview seems like it was explicitly non-technical, though.

“He kept talking about dead babies, failed relationships and the time he cheated in an exam in grade five. Fifteen minutes in and I wondered not whether I would hire him, but if he would kill me and wear my skin if I didn’t. Or did. Little difference.”

you think that's what it was? The people with 100% of the power in this situation did everything 100% correct and you're not victim-blaming at all?
