these are the general instructions
Toptal’s Design Team is currently focused on digital product design, and we look for designers with extensive experience in User Experience Design (UX), User Interface Design (UI), Visual Design and Interaction Design.
The portfolio should contain your 5 best projects, complemented with a short description of each. Please explain the scope of each project, your direct contributions to it, and the rationale for choosing specific design solutions. Feel free to show us multiple pages and screens. Having a clear overview of your design process is also essential.
