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.
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).
It's an easy leading indicator of who has their shit together.
It's probably at the same level of complexity, give or take.
