It wasn't a matter of, oh I would have done this differently, it was more like this company is full of people who have no idea what they're doing and I'd rather not be here .
I will say you should absolutely never talk about code issues at a current employer when interviewing. Who's ever interviewing you is going to interpret this as you being some weirdo who argues over tabs and spaces. There's not enough nuance communicated.
Maybe I'm trying to say you shouldn't take it personally when a company isn't a good fit.
