It's not uncommon to receive job offers that seem too good to be true. Unfortunately, out of every 10 job offers, only about 4 are legitimate vacancies and the rest are fake postings from fake recruiters. If you're contacted by a recruiter, the first thing you should do is check their LinkedIn profile. If their profile has few connections or incomplete information, this could be a warning sign that they're not legitimate.
There are many employment agencies around the world that advertise jobs with high pay and lots of benefits. A labor scam is when a fraudulent group poses as a recruiter and posts a job offer with an attractive salary. On their LinkedIn profile, they may type “jobs” as “jobs” or use an image with the text “jobs” to bypass the LinkedIn filter. Whether you're actively searching for a job, have your resume on LinkedIn or other career websites, or just occasionally talk to recruiters on the phone, it's not always easy to protect your personal information.
I usually get one or two direct job offers through LinkedIn each month, and many recruiters contact me for interviews. When looking for a job, it's not uncommon to receive multiple offers from different recruiters. I've received interviews that have resulted in job offers through unsolicited LinkedIn messages, so they're not all bad.
