It should have been HR that interviewed you, and your direct boss should not have been given specific information that would make them hold a grudge about anything you said. Sounds like that company has some issues.
If so where can i go read the rule book for the correct answers on all of managing people for all human endeavors?
It reminds me of people who are convinced that there is one true way to do "agile" and that every one who disagrees is somehow subjectively wrong because some blog post from some guy who went to some meeting 40 years ago kind of agrees with them.
Ok. Good luck with that.
If you’re looking for the book of these basic rules, maybe take an HR class?
I think your meaning isn't far off, the company stands to benefit from an informative interview.
