y'a t-il des fautes dans mes phrases en anglais ? merci à ceux qui voudront bien m'aider ;)

I'm studying in foreign languages in order to have a good level in English and Spanish given that languages are more and more appreciated in the labor world but I don't really have a clear idea of the job I could do. All I know is that working as a a mere employee wouln't be a job that suits me, I would prefer to be given more responsabilities so to have a more worthwile status in the company
