If you want to learn, you must learn all aspects. It depends on which aspect you want to do. It is impossible to learn an all-round player all at once. At that time, e-commerce majors generally did not involve design majors, so I won’t talk about design software. Let’s talk about the fact that e-commerce needs UI designers. At present, the demand for motion designers is getting higher and higher. For product design, you have to be able to sort out the needs, sort out ideas, and draw prototypes: Xmind, Mindmanager, Axure, Modao, etc. In large companies, there will be dedicated interaction designers to implement interactive demos and high-fidelity prototypes. ps: Product design is not the kind of design that draws pictures. Although you have contact with designers, you don’t discuss them. There are only so many softwares. I won’t talk about what they are used for. Non-professionals do a lot of things in operations. Basically, office software is enough, and there are usually various backend systems to use, not the kind that is external. Everything depends on data, so data statistical analysis is essential. I originally studied SPSS in school, which was necessary for questionnaire data analysis. Later, there were R and Python, but Python is more useful and can be learned first. OFIICE's own Excel (data analysis), Visio (process, mind mapping), and PPT are essential for writing reports. They are essential for getting started, but they are very simple to learn. Even if you don't learn the above, you can be fully competent for basic work with these. If product design is planning products, operations are selling products or selling goods through product tools, then development is the person who realizes software products, so it is not a development major. E-commerce majors still learn some relatively simple front-end interfaces, and may also involve the back-end and database, but after all, this is a system thing. I don't know how the courses are set up now.
