If you want to hide yourself from certain schools, Selected gives you that option. Once you've started to create your profile, you should see a tab called "Your new job" (as pictured below).
Scroll all the way down, and under the "Privacy" section, you can search and add/edit schools and networks you'd like to be hidden from.
Type in the name of the school you'd like to be hidden from and then click the "Add a school" button. Once they are added, they will not be able to see your profile on our platform or that you are actively searching for new positions. You can add more than one school, and always come back and edit this list.
