I would add to your list, what if the company with that job offer you applied to asks for your consent to do a background check on you (they do) and then they pay other company that specializes in tracking all your information (these companies exist)?.

omg people, dont do personal stuff on your work machine or connected to your work network. A vpn wont save you from all the software they install in your machine to track you. Use your phone with your mobile data.
