Part time uniqlo

Hi, I just applied for uniqlo part time at the non city areas through FastJobs on last Friday and I am just so afraid they won't see my email as latest emails are always at the top of the list and sat and suns are non hq working days.

How long does it usually take for uniqlo to reply the fastjobs application?

My friend got a reply in a day and I am so scared that my email wasn't seen at all, would really appreciate some replies telling me how long I should expect to wait
