⚠️ Protecting Job Seekers from Identity Scams
At System One, your privacy and security are important to us. As job-related scams continue to target job seekers, we want to help you recognize and avoid common recruitment fraud. Identity theft scams often involve individuals, also known as "scammers," posing as recruiters or employers to obtain sensitive personal information, such as Social Security numbers, bank account details, or copies of driver’s licenses, with the goal of stealing identities, accessing financial accounts, or creating fraudulent accounts in a victim’s name.
