The "Dunghill Road" looks a bit bogus, but one never quite knows for sure. On Mount Shasta there is a place called "Bumpass Hell," whatever that might mean.

I don't know if MapQuest covers Great Britain, or if GoogleEarth does street addresses, but you might search those. Don't buy any plane tickets until you get good answers, though.

Or it might be located on a reclaimed brownfield and actually be legit. Ask carefully.

An employer usually they call the candidates and interviewed maybe trhrough phones. I had a friend similar email only different company but looks similar coming from oil and gas company. If it is legit they should have called you, oil and gas companies are rich and selects cadidates carefully will certain processes. Beware of scams!

Google Maps gives the address for the postcode SA31 2AF as West Wales Hospital at Dolgwili Road, Camarthen.

The similarity between the two telephone numbers is open to question.

Simply send a mail to them and find. BTW how did they ever get your name? did you apply? are you considered a specialist in the field?

So there is your answer, yes it is a scam. Hope you did not give them any personal info.
