The question that raises from a process improvement perspective then is "were the first 3 rounds really effective tests?" Perhaps a better solution is not more interviews, but more focused interviews conducted by the people that actually have the knowledge and power to make the decision. (And if the knowledge and the power are divided among multiple people, another great improvement would be empowering the people with the knowledge.)
Yeah, it saves you money...by costing the prospective employee. There's only so much we as employees can or should be willing to give up for free, and it's 3 interviews.
I also question if more than that is really improving the quality of your hires. Far more often (100% of the time, in my experience), multiple interviews are more a symptom of bureaucracy; multiple managers insisting that they get to stick their fingers in the pie, rather than actually learning anything more meaningful about the candidate.
Never do more than 3 interviews. And that's assuming they're relatively short, maybe 1 hour apiece. Any more than that, and they don't want you bad enough.
I like to use the weird spells that players rarely take due to being less than optimal. That way they still get to use them situationally, without having to "waste" a slot.
The exception is when there's a particular story reason for a certain type of item to crop up; for instance, a group of assassins hunting a powerful mage might have a lot of dispel and antimagic type things.
There are probably legitimate uses out there for gen AI, but all the money people have such a hard-on for the unethical uses that now it's impossible for me to hear about AI without an automatic "ugggghhhhh" reaction.
And America wasn't actually empty frontier, either. It was full of the native people that had been living there since time imemorial, and the ex-europeans slaughtered and plagued their way through.
"You go to ask your Grandpa about it. He tries to explain but is so fucking racist you can't even tell if he's still speaking common. In between gibberish that's probably old-timey slurs, you pick out something like 'follow the quest hook' and 'the dm already told you where to go'"
What's his deal?
