Hi irishcabincrew,
Not aware of a maximum height limit being in place. There were at least 2 very tall girls who got through when I was assessed so whether that sets a precedent I don't know, but in general you expect guys to be taller than girls anyway.
The assessment day is group activities.
Speaking a second language is definitely an advantage due the diversity of emirates pax. Don't think that they check your fluency.
No dental examination at the assessment stage.
Previous experience has surely got to be a desirable asset however, I think its how you come across aswell. If you look around this forum there are lots of people who had never been cabin crew before joining emirates.
When I was assessed it was a 50/50 split ex crew or current against non crew selected for final interview; 2 of which were guys.
I think any good interviewer will try to make you feel at ease (and they do) to get the best out of you, after all their job is to get as many suitable people into the role as possible.
Hope this helps and good luck
