You may see advertisements for jobs that are scams on this page, just because you see an ad here, that doesn't make it a legitimate company. Carefully investigate companies that you are interested in.
Scammers know that finding a job can be tough. To trick people looking for honest work, scammers advertise where real employers and job placement firms do. They also make upbeat promises about your chances of employment, and virtually all of them ask you to pay them for their services before you get a job. But the promise of a job isn't the same thing as a job. If you have to pay for the promise, it's likely a scam.
