In every single job interview I've had, I've asked some variation of this: "what's it like to work here" or "what's the culture like". Every time I've received honest, thoughtful responses. Every time I took the job or knew someone who did, the answer was verified.

Maybe it's not the most fail-safe way to get a good answer, but the article make it sound like the recruiters/interviewers are adverserial and have rehearsed talking points about shilling culture. If you can't get an honest answer from a recruiter to genuine questions, that's a red flag.
