Flunking my Anthropic interview again

The reasons why companies hire or don't hire someone usually have very little with the candidate themselves. From my experience, whenever this machine needs another cog, almost any will do - usually the first one within reach. And when it doesn't, not even the shiniest one will be of interest. So it's probably nothing personal OP

Or maybe it has everything to do with the candidate. They author recognizes they have spent much of their life being an unlikable jerk. Past actions can come back to bite you.

I tend to agree, which makes it all the more amusing that companies brag about being so selective. It seems like largely artificial and random selectivity.

Nah. Every company has its lore about what makes a good candidate and they try to test for that. The lore is often rubbish (as in: there's often little correlation between interview performance and on-job performance), but there is still a process and that process rejects most applicants.
