How should interior design go to the high end step by step?

Tell me about my experience. After half a year, the renderer jumped directly to a small company to be a home improvement designer. After two years of training, they made some small projects themselves, and then transferred to a first-class tooling company to be an ordinary designer. A year later, they became design directors, and now they are sent abroad as project leaders. I plan to go it alone at present. Making renderings is my skill to cut into this industry from graphic design. I didn't like drawing construction drawings at first (it was boring). I also have a little art foundation, so I choose to teach myself renderings. It is right to think about it now, and interest is the best motivation. Of course, it is far from enough to be a designer only by social renderings, so I found a small company at that time. (The conference renderings are in great demand, and the construction drawings are passable. ) When you get this opportunity, hurry up and talk about bills, construction technology and materials. In short, we should often go to the construction site to see more and communicate with workers more. At this time, you can solve most of the less demanding design projects. Then when I left, I felt that the bottleneck had arrived, and I couldn't improve much if I stayed. So did the projects of smaller companies. At this time, some work experience in tooling projects is urgently needed. If you want to continue to improve, all skills must be upgraded. Then I found my present company. At that time, I talked frankly about my own experience and career planning, that is, I lacked experience in tooling but was relatively independent (the nature of my previous work determined that the designer was responsible for negotiation, design, construction and payment). The person in charge may be moved by my frankness, and may think that I am a person with goals and plans, and make an exception and let me join the job. After I entered the first-class company, I supplemented my own construction drawing as quickly as possible (the previous construction drawing was not standardized) and put forward my views on the work to the leader. A year later, the company put me in charge of the design team of six people (I am not the best in terms of professional ability, but the leaders took a fancy to my better coordination ability)
