This sounds crazy to me. My last company would freak out if the dev team got together and discussed the person's politics and if we thought they should be hired or not based on that. I hope they do stop this.
The more i think about this the crazier it sounds. Imagine a Houston oil consultancy firm discussing a candidate who applied and asking "when we talked about lowering taxes, did the inflection in his voice sound real or feigned?". This is what an "old boys club" looks like.
