During the interview they said that the roster would look like this:
MON STN-EWR
TUE. EWR-CDG
WED R/D
THU CDG-EWR
FRI. EWR-STN
Arriving back in STN on SAT at 10am.
Than you have Sunday off and Monday afternoon you start again. This repeats itself over your three weeks on and at the end you have 7 days off. They were planning on doing 4 Atlantic crossings a week and 12 in your 3 week on block.
Personally I have declined their offer as 3 days at home in three weeks is just not enough. Especially after a week of night duties.
