Job skills are translated "des compétences" ; you can also say '"du savoir-faire" when speaking of craftsmanship or in technical settings.
You would say 'compétences transférables' in French.

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.
