Generally there UI and UX designers works are slightly different where UI designers focus on how the product has to visible to the user they work on color, font etc while UX designers work how to provide smooth experience to user while using their products. All designers won't have the same type of work based on their experience for example junior designer only work on basic elements, experienced designer work according to user needs whereas professional designer works on how to improve their company's growth through their products. So if you are from a nontechnical background and thinking to learn this technology then I recommend you go for UI UX design course from Intellipaat where their courses are designed in such a way anyone can learn from ground level to advanced level.
