Fraudulent individuals post job advertisements on websites, or social media offering employment positions and possibilities to the public if they submit their curriculum vitae/resume, call the advertised contact numbers and part with certain amount of money as admin fee.
Most reputable companies who have position to fill use formal procedure with all career opportunities clearly listed on their own website. And do not require candidates to make certain payment for job opportunities.
How to protect yourself:
Absolutely DISREGARD any message with semblance of the aforementioned
Do NOT supply any personal details to anyone
DONT make any payment(s) to any individual or into any bank account via the job websites, SMS or email
Immediately REPORT to law enforcement agencies.
