I’m a fairly big and strong dude. I hate my current job and want to change careers. I think I would be a good goon, like a character Batman beats up before a boss fight in an Arkham game or that Noir detective outsmarts. How does one acquire such a job? I don’t see any posting on Indeed.
Go to the local speak-easy.
Insult the guy who asks for the passphrase until they send out their goon to rough you up.
Prove your mettle in melee combat, then ask for a job.
