Generally speaking, people over the age of 40 rarely need to submit resumes, because most of them either stay in the system, have stable jobs, are well paid, and will not easily change jobs. But in either case, it is the embodiment of strength.

For people over 40, energy and memory are greatly declining. It is undoubtedly difficult to learn new knowledge or skills involved in a new project in a short time. On the one hand, they have to deal with heavy work, on the other hand, they have to take care of their families, so they really have too little time to study. But if you are an excellent person and a leader in the industry, you don't need to worry about this problem.
