For many employers that can be an advantage, since a business wants to develop markets. It is really an asset when we provide a candidate who meets the profile for the position and can develop new markets. I am thinking, for instance, of a business here that operates in English only but wants to receive the representatives of a Quebec business in French. Having a francophone employee is an asset, and people know it. Some jump on the opportunity and encourage that. It can be an advantage, depending on the region.
They always look favourably on the fact that the candidate knows the first language they use well and knows another language. It is always an added value. It can certainly be a sales argument.
