Internet-based social media platforms and online databases do not operate in a private sphere. They store everything public, everywhere, and it is available to everyone – even employers. Complete internet anonymity does not exist. Many things about you and your personality beyond your resume might be accessible. These include your support of causes, interests, or ideas.
Anyone can type a name in a browser and find references to public information with just a few keystrokes. When personal details become accessible to employers through web and app activity, it is only natural for them to form opinions about the person they have searched and whether that individual aligns with the company culture and job based on the content returned.
