Apols if this has already been covered, but is the whole thing in the can, edited and packaged before it goes on TV, or by the end has it caught up and is in "real time" (maybe a few days delay) Are they still living in the big house in Kensington/Chelsea or is it all over now?

I thought that like Masterchef, it was all over before it was shown. It looks to me like most of this was filmed last summer/autumn. That might just be my assumption though.

Filmed in the autumn, over 7 weeks. They film 2 "Your Hired" endings and the final candidates work for AMSTRAD for a trial period. He decides which ending is aired during the week running up to the final being aired on TV.

Wow thanks for that! I didn't know about the two endings thing. I just thought that the candidates were contracted to keep schtum.

No problem!

Double endings are confirmed here and here again
