What’s the quickest way to assess company culture?

You go to their toilet. No, seriously, you ask for an excuse and you go check the bathroom if it's clean, if there's some paper, then you get a feeling. Also, you look at the employees, you look what they look like. You go to Glassdoor. I've just refused a company even to go to the first stage because I've checked their reviews on the Glassdoor. I once didn't buy a sofa because on the Glassdoor, people were saying that there's sexual harassment in the production line, people are discriminating females, so I said, no, I'm not buying a sofa from you guys. So you do your background check before you go to the office because if it's really bad, you'll find it even before going to the office. If they treat somebody unjust, then it's not the place to be.
