H&M interview questions

I applied for a Visual Merchandiser position at H&M. They called me and had my first phone interview a few hours after I sent my cv.Then called me the day after for a follow-up interview.I was interviewed by the head of visual and an HR manager.The interview lasted 1 hour and they seemed pretty excited. Two days later I had a callback and asked me to go directly to a store for some skills tests.There I met with the visual of the store and went through a few tests.Before I was even home,an hour later she called me for another interview the day after.For my fourth interview,there was a manager and another head of visual if I remember correctly.They told me that this was the last interview and they will either call me for an offer If I got the job or email me If I did not within two weeks. It's been almost 3 weeks and haven't heard back yet. Saying I'm sick to my stomach would be an understatement as I thought I had the job and now I pass my days starring at my phone,wondering what happened.
