What is the employment prospect of petrochemical industry?

It would be nice to go to the petrochemical petroleum department. Petrochemical and oil companies are generally responsible for separation, some for technology, and some for instrumentation. Generally speaking, it is easier to be a supervisor or a director. It's hard to say that it depends on your own ability, but in my opinion, you think too far and it's unnecessary. Few people in today's society work in the same unit all their lives.
