This isn't screening for 'culture fit' though and I'd sincerely recommend avoiding referring to it as that. You're screening for strong communication skills and that's absolutely fine (and highly recommended).

Interviewing for culture fit (as you've seen in the responses to your comment) has an extremely negative stigma attached to it for good reason.

I strongly agree with this. “Culture fit” is one of those concepts that often disadvantages “others”. This is something we may not be able to avoid without putting in place safeguards (concert musicians were predominantly male until blind auditions were used - and it turned out that female musicians play just as well or better).

As I mention above this is often not a result of bad intentions, but of implicit biases that have an effect on our judgements even if we are fully aware of them and explicitly try to avoid them.
