The "Alumni" section on a company's profile includes all the talents who have worked or currently work at that company and have listed their experience with it in their CV.
For example, if you add a position you held at a specific company to your CV, your name will automatically appear in the "Alumni" section on that company’s profile.
If you do not want to appear in the "Alumni" section of the companies you’ve worked for, you can set your profile to Confidential.
