The short simple answer is “yes” balance to daylight color temp on everything.
The more nuanced answer is; “maybe”.
Indoors, there is no hard rule you must favor tungsten or daylight for the white balance: it’s all about the look you are trying to achieve, and which balance makes that look easier to achieve.
There is no one “normal” “natural” interview lighting setup. Once you do your white balance, that is a base level for the color reproduction, which you would then probably start to enhance in one way or another to get to a final look for the colors, on the set, or in post. A shot white balanced to daylight and one balanced to tungsten are, all other things equal, going to look pretty similar in color rendition with, one a little “warmer” (the tungsten balance) than the daylight. The difference can be subtle, or blatant, if you mix sources in the shot with varying temps. What kind of instruments are in your studio? Are they fixed to a particular white balance?
Also, when you light for “daylight”, I gotta ask; what time of day is the daylight? Sunrise/sunset is going to be much warmer than high noon. Your “daylight” at sunset could look closer to a tungsten white balance at that time of day.
If you are going for a classical three-point-lit, two-chairs and a potted plant kind of interview set, I’d suggest an indoor white balance.
