That's not a valid BT address, is it? They have a convention for all their addresses, and this just doesn't look like one.
With .ch where .com or .uk should be, it looks like a Switzerland address.
Just more phishing... and probably just made to look like Switzerland as well.
Could be a scam to get peoples details, by thinking they were applying for a job.
UPDATE
Just checked, and it IS a rebranding website where you can register one address and use another.
