The job of UI Interaction Designer (UID) is to design the part of product that interacts with users, that is, after the product manager (PM) finishes digging and combing the requirements and functions of the product, the subsequent process, structure and layout should be handed over to the Interaction Manager (UE) and UID, and then the UID is basically completed, and then the visual designer (GUI) beautifies it. UE and UID should understand and determine the requirements of product handover, and internally design and communicate the interactive part with GUI.

Becoming a real UI designer is more difficult than expected, but a well-paid designer must have interface design, GUI interaction design, "cross-border ability" to master various cutting-edge plug-ins, and a customer-oriented person.
