Power move: Make up your own acronyms to use back at them. "At my old company we had a really robust GUPO, and our FUM was in a class of it's own." Do not explain what they mean. If asked simply laugh, and say "You wouldn't get it. Super niche."

"You'll notice we use a lot of acronyms here."

Yeah, so did my last 3 jobs bucko.

I mean to be fair this is just any profession. Modern highly abstract processes often have long names for things so they get acronyms. But if you’re a new apprentice at the car factory, and your foreman points to the rack that’s got all the different types of hammers on it and asks you to fetch a planishing hammer you’ll be just as lost as the new office admin being asked to fill in a GARF.

the worst is when they do this in interviews. apparently during the agile dev craze some middle managers mixed the idea of 'KPIs' into the granular work-tracking that is involved in 'agile software development'. apparently 'key performance indicators' which were previously. only known to the business analyst class of office priests has been foisted upon engineering departments too

Slightly aloof David cross??

Whenever I start a new job, I make a little text file called "acronym soup" that I fill in with everything. Then I can ask someone later what it stands for. It's always funny how many people use regularly without knowing what they stand for.
