Judging from the technology you have mastered, it's not bad. At present, ARM is widely used in high-end embedded systems. If you can master it skillfully, in my opinion, embedded development companies are preferred. Because you can't specialize in high-end system development in most factories, you may be asked to do many things unrelated to your major. In addition, as far as I know, most of the automatic control in the factory can solve problems with PLC or ordinary single chip microcomputer, and ARM is rarely used, which is a pity for the ARM technology you have mastered. After all, a lot of efforts have been made. But in some big companies, there are special development departments that need talents in this field, which is of course suitable for you.
Give some advice, for reference only.
