For the most part, CV-building is standard - as long as you know the basics, you can apply for a job anywhere. That being said, certain things about the job-hunting process - such as how you search for a job, what your CV looks like, what you include in a cover letter, etc. - are country-specific. So, if you want to get hired in France, knowing the details of what a French CV should contain can make a huge difference and substantially improve your employability.
