Of course you’ll never hear anything else; no interviewer is going to say “we’ll attack you like starved hyenas,” but in real life that’s the response you’ll get pretty much every time.
The question is the visibility of the struggle as the interviewer tries to conceal his own irritability at the temerity of a New Guy who would question our beloved catfight-on-the-keyboard coding practices.
Because you can see his monitor in the reflection of his glasses and see that his code is flush left, which means he’s doing mid-function returns, which means he’s a moron. Indentation is just so awful!
So you know that if you get a chance to learn their code you’re going to see the standard-issue industry-standard garbage; unplanned, unstructured, illegible as fuck, and, no, nobody is going to be receptive to cultivating better practices. They cover the shitness of their work by writing unit tests, not by ever seeking to be better.
