>I haven't seen much of a bias towards seeking out a predisposition to loyalty in employees except among authoritarian small business owner types who invariably underpay.

It's easy. Some red flags:

"This is not a 9 to 5 job, you should know that. But that's normal in this industry"

"We're looking for people who are passionate about their work"

"I won't sugarcoat it, there are good and bad weeks" in terms of workload and hours

"We see a gap in your resume here a decade ago - may I ask why you took time off during this time"

etc

Those are signals.

There's a normalization of sociopathy in the hiring process. That's how we filter. Or maybe it's just financial services?
