1. Does a mobile game developer differ from a developer of other kinds of apps?

In general, game development is similar to the development of any application. The programming languages are the same: Swift, C++ for iOS, Java, or C# for Android. Usually, small companies use the Unity engine in combination with C# and JavaScript.
If the app is intended for both iOS and Android, there must be at least two developers on the team. Don't forget that you need not only developers, but also at least a UX/UI designer to create a mobile app.
In the first place, decide on the platform. If you want to develop both iOS and Android versions at the same time, you should hire two developers. Write a job description with specific tasks and requirements. Post your job on the specialized Telegram channels for IT professionals and on job boards. In this way, you can find a developer of the junior or, at best, middle level. It's more efficient to search for competent middle and senior developers via LinkedIn. And it's even better to contact a recruitment agency that can find the best specialist for your project.
The best option is to hire a developer whose released apps are available on the App Store or Google Play. You can download an app, try it out, and make conclusions on the developer's skills. Of course, it's also important to conduct the interview correctly, and check the hard and soft skills of the candidate.
