DH (celiac and casein free) is up for a job opportunity.
So far, the application has been handled online and there have been emails and phone calls with the recruiter.
If that goes well, he gets an invite to a week long "orientation." Job offers are handed out (or not) on day 5.
They put you up at a company owned hotel and breakfast and lunch are catered.
I know he can handle feeding himself. There are fridges, a microwave in a communal kitchen area, a grill and he will have transportation. He's great with a camp stove and can be as paranoid/careful as required in this communal area.
At what point does he mention celiac, if at all? It IS on his application by way of a required medical checkup.
