If you need to settle for technical correctness that's fine.

Fortunately we have the resources to hire for technical correctness and a bit more than the minimum when it comes to being well rounded with your ability to understand problems, communicate, etc.

We don't want people who jump to conclusions like "the interviewer is asking me to recall things I don't remember" under the guise of "precision" instead of just asking

It takes commensurate pay/interesting work/an attractive workplace/etc. which are out of a single interviewer's control, so I never hold it against those who don't filter to any of that.
