How do you know if a job offer is a scam?

Research the Job and the Company:  Visit the company's web site and if they don't have one or it doesn't fit with how they describe the company, consider that a red flag. How professional is it? Is there contact information? Are jobs and career information posted on the site?

Use Google: Use Google to research the company. Search by the company name (if the company won't give you a name, don't bother applying) to see what information you can find. Take it one step further and search by "company name scam" to see if you can find information about reported scams.

The Job Details: If it isn't listed in the job posting, try to find out if there's a salary or if you're paid on commission. Ask how much you're paid, how often are you paid, and how you are paid. If the company doesn't pay an hourly rate or a salary, carefully investigate the details.

Check with organizations like the Better Business Bureau and the Federal Trade Commission to see if the company has been reported as a scammer.

Do Not Pay: Do not pay money - for anything. Legitimate employers don't charge to hire you. Don't send money for work at home directories, advice on getting hired, company information or for anything else related to a job.

Check the Company's References: References work both ways. You are as entitled to check a company's references as they are to check you out. Ask for references if you're not sure if the company is legitimate. Request a list of other employees or contractors. Then, contact the references to ask how this is working out. If the company isn't willing to provide references (names, email addresses, and phone numbers) do not consider the opportunity.

Forget Getting Rich Quick: Avoid listings that guarantee you wealth, financial success, or that will help you get rich fast. Stay clear of listings that offer you high income for part-time hours. They will do none of the above.

Be Careful: If it sounds too good to be true, you can be sure it is. Also, read any "offers" you get very carefully. One candidate for employment got a very detailed job offer from an employer. The only problem was that she hadn't applied for the job and buried deep within the lines was a request for her bank account information, so the employer could pay her. It was a scam, of course, but with some of the well-written ones it can be hard to tell.

I usually do that when the subject employer contacts me and list the prerequesits to win the job. For mail offers, the computer will tell you when your receive a scam messages and that is almost always correct.

I recive a call from india hyderabad UP and they after some talk request me for the fee euro.

i give him a good lesson actually.if some body need you how can you give money from your side.he hangup then.

 simple formula =If they asking for money that's a scam ....we were going to earn money with job not to give.

I think that the best way to protect yourself is to conduct a research. I have not been scammed before because whenever I see the company or the services I am not familiar with (or their offer is too good to be true) I go online to look for the information about them. But I have to say that scammers go above and beyond to pretend that they are a real deal. They post fake reviews; they create profiles on social media and buy followers. It is getting really hard to recognize what is real and what is not. You have to go through all the steps you see here, also I recommend reading something similar by Resume Writing Lab here http://resumewritinglab.com/blog/avoid-job-search-websites-scam/ . It is always better to double-check the information to be on a safe side.
