If a job listing or offer requires some form of payment from the job seeker, this is likely a sign of a scam. This also includes if a company asks for your bank or credit card information. Additionally, if you receive a paycheck from a company and are asked to deposit it and then send some back, this is also a scam. By the time your financial institution realizes it's a bad check, the money you sent back will be long gone.
If you’re contacted with a job offer without applying or after an unusual interview process, such as an instant messaging system, you should approach with caution. Usually a quick Google or Better Business Bureau search will reveal what you need to know before moving forward with a company or if it's even legitimate.
Scammers will use certain phrases that will pique the interest of a potential victim such as ‘unlimited earning potential’ or ‘earn money fast’ or an usually high salary. Do some research on similar positions and see what they’re making for comparison. You should also show caution if you receive an offer for a position for which you did not apply.
If you receive emails offering a job that is full of spelling, grammar, and punctual errors, this may be a sign of a scam. If the tone of an email feels weird, such as being unprofessional or asking for too much personal information right off the bat, this may also be a red flag.
