Hey mapsyd,
I did the AD and then got told I had progressed three days later to the online assessment, if i get through that, which I'm hoping I do, we get an interview eith the cabin crew manager at the airport and reference checks.
Your assessment day sounds interesting, I was one of a group of about fifty people from what I could tell, and we were all afforded a one on one interview with a recruiter. Like at your AD there was no role playing or problem solving activities, a bit different all the same. The online verbal reasoning test is a comprehension-based test, quite straight forward but with a time limit which makes it more difficult... I'm sure you will have to do this test at some point if you get through. I did it nearly two weeks ago and I'm still waiting to hear back, so hopefully I will this week!
