No, it is not an offer, only an indication of a willingness to consider any offers and counter-offers.
If this is not something that you have initiated or if you are not in that field of business then I would say that it is fraud. However it may be worth your while to contact the real company and ask them. Do not contact the people that have contacted you with the offer. There are many frauds out there and they want your personal information so that they may work on stealing your identity for credit. It is amazing what they can do with just your name and birth date. Give personal information to no-one unless you are 100% sure that they can be trusted.
