hi, i am quite interested as well in doing an assesment day with gulf air, they´re coming to spain soon.
i attended several assesment days in others airlines, and i imagine the sequence will be the following approximately:
- height reach and weight.
- correct documentation (passport, studio pictures, cv, academic and working certificates.......)
- english test
- one to one interview, group discussion (in etihad you have to choose an object.... newspaper, pen, water, mobile,........
- final interview
regarding grooming, yah of course make sure you wear a fresh make-up, neatly tied back hair, business attire (knee lenght skirt, high heel shoes, stockings, not revealing clothes......)
good luck
