yep i found this one out the hard way when applying for a job in the uk at currys (similar to best buy like in the op)
didn't get the job of course, that's fine, whatever, move on and go to next application
what i learnt afterwards though was that, they don't hire for currys/best buy based on your actual understanding of tech. they hire on your ability to sell the items, and help customers engage in excess consumerism.
the main point being, i obviously wouldn't sell anyone a $99 gold plated hdmi cable. because firstly, that's unethical profiteering, and secondly, i know that a $5 would do the same job. i would point a customer to the $5 cable, it's the correct choice. but this is why i am unhireable for this job.
currys, best buy, euronics, mediamarkt etc need to hire people that can sell the $99 cable. to do that, they counterintuitively have to hire people who don't know enough about tech. reason being, if you don't actually know about tech yourself, you will think that the gold cable is better, and you can then do a more convincing job of selling it. plausible deniability. apply this to every item in the store. you want someone who can push 8k tvs, beats headphones and smart fridges. not someone who will guide the consumer to what they actually need for their use case.
it's the reason why you go into these stores and the staff don't have a fucking clue about actual tech questions. they were hired precisely because they don't have a clue.
