The company is a research and development and production company, and the company is not too big. But still human. As for the development space you mentioned, it depends on your work and your subsequent career planning. The salary is also negotiated by yourself. If it is a fresh graduate, there will generally be a fixed salary standard. To struggle for a period of time depends entirely on personal ability. Any company is the same. If there is an opportunity, it depends on whether you can seize it. People who work hard will always have a chance. Come on!
