Havent time to write a full report on it now I'm afraid.
If you have done day one, you'll have the list of qualities they are looking for. Fairly obvious really, someone who can get on with someone they don't know in a cockpit to produce a safe outcome of an unusual situation, manual handling is just one of many things.
All in, including the briefing it lasts around 3 1/2 hrs, so prob 2 hrs (1 each) in the box.
