You're entering the Schengen zone and the immigration official will only be interested in ensuring that you have the right documentation to enter the Schengen zone. He may ask you a couple of questions about how long you're going to stay, financial resources and so on, but arriving in GVA and going to France is something the immigration officials see hundreds of times every day. GVA is the local airport for the whole of that area of France after all.
It makes no difference whether your long-haul flight was to CDG, FRA, AMS or GVA. Each of these are Schengen entry points and they would each carry out similar checks.
