If you’re applying for a management role then asking about how dealing with employees who are problematic in a conversation about a team that’s had some painful experiences might be OK, but if you were asking that as an IC then it would come across very strangely because the obvious implication is “I am going to be a problem”
It is undeniably an awkward question to ask, but valuable. How to weasel this question into the interview is another matter…
I'd want to ask: What are they, if any? Could I instead pocket the money you would have put to health benefits and then make my decisions post-tax? Do you offer Direct Primary Care? What does parental leave look like?
