bon travail
You can say that the boss hired you for the wrong job. Emphasize that the new job for which you are applying matches your skills better.
I think that would mean any specific skills that are related to the job your appling for should be put in. So if you were applying for a let's say, pre-school worker you would say you have a skill or exprience with children.
