Hi Yamanna,
We are in the same boat. Hubby just got a job offer from Davors Offshore. Their website seems to be legit, but upon closer inspection, it doesn't have any "media relations" listed, or press releases, or even a place for investors to click on. I've never seen an oil company that operates rigs offshore to not include these three essential information pieces.
Additionally, when you search the domain through the who is registry (I normally go through www.whois.sc), you get that this domain is registered and hosted in Moscow, Russia. There is no way a UK company would ever register anything legitimate in Russia.
Coupled with the news clipping from the Irish news previously posted, I feel that yes, this company and any offers of employment should indeed be considered a scam.
Furthermore, hubby was also approached by Tupras (under the email info@tuprasonline.com), again with a job offer. We've since discovered this is also a scam and the real Tupras has that email (tuprasonline.com) listed on their career site as being scandalous.
Since Tupras' actual website is http://tupras.com.tr/ it was kind of off that the emails were coming from tuprasonline.com. That's another flag.
Wishing your husband the best in finding true employment.
