That makes sense to me. Discussing non work related politics with coworkers seems like a bad idea. No idea why that was downvoted.

I had a weird interview last year. After about 30 minutes talk, the guy started shifting to politics and expressing his ideas about Europe, the UK, refugees, etc. I didn't want the job anyway so I told him that I don't agree with his (barely contained) right wing opinions. He immediately told me that things are not going to work, and I agreed.

Having early 20 somethings doing interviews alone is asking for trouble. Talking about politics during an interview strikes me as a recipe for disaster by creating a highly homogeneous environment. I like variety
