Obviously will depend on how many people will be there on the day,if you have 8 guys in the 9 am session for example,you divide it in 2 or 3 groups,while one group does the tests others are interviewed,and other watch a presentation,if you have some good 10 people assesing you is not impossible to be done in 2 half hours!I'm at recruitment in my company and we asses pilots and crew,sometimes 25 pilots per session a day.
Ah,roll over,what do you mean as the expats will be treated differently?whats the background on your assumption?
