It is a role that combines unreal engine development with UI design.
The portfolio I submitted demonstrated knowledge in game interface design and game development with Unreal Engine and Unity. It is important to demonstrate and highlight the UI design process with a document.
The interview, however, focused on the handling of the widget system in Unreal Engine. About the use of the unreal library called UIMaterialLab, which seems to be an industry standard when it comes to saving resources doing UI. Using materials, reducing the weight and demand when loading textures.
A plus is to know C++.
