I've only read headlines and heard from friends working in larger cities for larger companies experiencing this, so obviously it's not something which is happening all the time everywhere, and based on my quick research it seems like a lot of news came out around 2012 about this issue: https://www.aclu.org/blog/privacy-technology/your-facebook-p...
I would act the in the same manner you would as well, it's not worth working for a company if they don't have some very basic principles and it's a huge red flag. If they don't respect your privacy in the interview, they probably wont respect it in day to day business. But just like you explained we have to be careful because there's a lot of people who don't really have a choice, especially in today's job market here in Australia; a lot of people would have to decide between privacy and their ability to pay the power, rent, food, etc.
