Pilots and doctors are exhaustively certified for a very narrow set of work. A cop gets a title, to perform a job that's identical in every part of the country.

Software development is neither exhaustively certified, nor narrow, nor perfectly transposable.

Developers want a 15 minutes interview, but also scream "Would you ask a builder if he has experience with blue hammers specifically?" when they get denied an interview because they do not have experience with the exact tech stack of a company.

Because that's how pilots and doctors work. They not only need to have experience with a blue hammer specifically, but it needs to be exact same make and model.

Imagine if a GP claimed to be neurosurgeon because they cured a headache. Developers get to call themselves fullstack the day they modify an API route.
