in the past i starter a job in (le métier) so i have some experience in the field compare to other people who have never worked.
voilà merci :).

I have never worked in (métier), but I am very responsible and committed with what I do. I am mature and I'm ready to take risks. I may never have done this job, but I am willing (ready peut aussi se dire, mais ça t'évites des répétitions) to learn about it. Also, taking care of others is my priority!

Ici cela dépend de ce que tu veux dire, taking of others signifie prendre soin des autres

caring about others voudrait plus dire se préoccuper des autres. Il y a une petite subtilité :)

That's why I think I would be good at (métier)

La c'est juste la grammaire

In the past I have started a job in (métier), so I have some experience in the field compared to other people who have never worked.

Quelques fautes de grammaire, mais c'est bien :)

si tu as d'autres questions n'hésites pas

Bonne soirée !
