HMSHost Food and Beverage Associate interview questions

They phoned me for an interview two weeks in advance ( in my opinion they didnt need people). when at point of interview, dublin airport beside escalators, they scheduled 3 people at the same time! 1st boy was maximum 5 minutes, then it was me and i think i was longer but i dont think that much longer. There were 2 girls, but making questions just one of them.
