As a practicing EE / RF comms engineer, I will say that it is very obvious when you're working with someone who thinks that their EE coursework wasn't useful for the real world.

As a practicing EE (power systems), I agree. It often becomes clear when someone is unable to distinguish a practical limit (this equipment is not rated for X, our operating procedures prohibit doing X) from a physical one (X is not possible because of underlying physical principles).
This. There are so many real world, practical, and pragmatic uses for EE. This example, which is basically knowing that the hardware specifications cannot meet the claims that are being made about a product, in an accurate or reliable fashion, is one I use on an everyday basis.

You don’t fall for marketing gimmicks.

Another thing is you know the relative price (ballpark figure) of the technology, as in how much it costs to make something, often just by eyeballing the actual product or by looking at its specifications. Sometimes this translates to more abstract and somewhat unrelated fields such as medications (if you read the patents and study them).

Yeah I have run into plenty of EE's who don't understand how to model a simple filter, for instance.
The first interview question is always an RC filter.

It's an easy leading indicator of who has their shit together.

RC filter is like fizzbuzz for EE.
One of those is a basic building block used in pretty much everything, the other is software bullshit.
Looping through a list of items, and doing different operations based on their value is an extremely common occurrence, and you’d hard pressed to find a codebase that doesn’t use that pattern somewhere.
Welp, this is why interview fizzbuzz exists, because some people think of it as "software bullshit" instead of the simplest possible program you can imagine that should come out as fast as you can type it.
I feel attacked. I'm a DSP engineer and I haven't implemented an analog filter since I graduated. If we got into detail on RC filter gain and phase shift I'd fail. Do I have to give my EE degree back?
No, but you at least realize an analog filter is a thing that exists. You don't remember the specifics, but you could study them if you needed to.
As an EE you should know what goes in front of ADC to avoid aliasing.
Don't the software methods have very similar problems?
fizzbuzz is literally a filter, albeit digital, and it involces a circuit, well a loop in most realizations, too.

It's probably at the same level of complexity, give or take.

And, like fizzbuzz, lots of people fail it.
yep exactly, even with training and degrees and claims of competence
