Why? How can you know this if you haven’t yet made any films? I am not talking full length films, I am talking about the type of short films that HS students might typically make.
I also expect there are film companies in your home country? Start contacting people in that industry and network with them. If you live close to any, perhaps you could get a part-time job or volunteer role. My last advice would be to start making films, does your HS have a filmmaking class?
