Thanks Chupachup and Montreal76 for your great replies!
I guess I'll skip a week of school and focus on the EK interview then.
I have some other questions now.
1. I'm in my last year of university and I'm worried if being in school would cut me off. I have about 3 years of experience working at restaurants, and this is the only customer service oriented work I had. Would this be sufficient enough?
2. I'm wearing braces right now but taking them off by the end of this month. Would this count as another no-no?
