Just found out that mcdonalds rejected my application, what do i do now

Ah, yeah there you go. Most managers at Mc'ds are really looking to hire 'bubbly', fun social people. It's nothing personal, but they want to keep the work force homogeneous and fun, because if everyone is miserable it spreads to the customers, they also have to keep the work fun or no one will want to do it.

Keep trying all the same user.

Trades
Factories
Always hiring and all you gotta do is show up/be safe
