I have been flamed for saying this in public, and I do not know how it will be received by an HN crowd, but someone who enjoys being a meta employee is a red flag.

Either they are actively a narcissist, actively immoral, not intelligent enough to understand the vibe there, or they're actually unhappy and not being honest enough to tell you they hate it there. I have a hard time envisioning any other possibility. The place actively filters out morally coherent and intelligent people.

Yes I was there.
