A lot of people tend to mention a second language on their resume. This is of benefit, UNLESS, they are not fluent in that language and wouldn’t feel comfortable using it in a business setting. If the language was spoken at home and you are fluent in the spoken word but not comfortable writing, indicate this on the resume. If I ask someone if they are bilingual in French and they say “I took a little bit in high school”, I have to wonder why they have put French on the resume. If you can’t use it…lose it.
