I was one of the applicants for his job offer. To be honest, I had some suspicions and doubts about him ( not scam but how serious he was ) even before hearing about what happened to the OP. Going back to my conversation with him, I think he was likely looking for someone with an important Discord account. I can't say for sure, but it seems that @saruc was behind the bot trap that was used to hack OP’s account. He left the server immediately after the incident which is suspicious AF.

The screenshot kinda seal the deal for me, their insistence on people who currently moderating discord shows that OP's suspicion is true. Leaving negative tag as well so any discord admin who see their ann thread and intended to apply could proceed with caution.
