The process is only one round, it involves interview and test parts. Questions relate to basic knowledge about UIUX design skills, such as the design process and principles. With the test part, the interviewers gave me a current design and then asked me how it was good and bad. You also have to make some improvements to them. They want you to design a mockup to deliver your ideas. You clearly present your ideas to prove you understand their problem well and your solutions could work.
