there is this organisation called 'oil carrers .com' how genuine is it?

Answer 1

That is not the name of an organization, it's just a domain name for a website.

You can try to find out the domain holder's name by doing a "whois" search on internic or other whois service.

See if you can verify that the business has been properly established and exists in the area where the domain is registered or you can use the contact information to request such information.

Make sure you spell the domain name correctly when you search. I think you may have meant oilcareers not oil carrers ...
