Which is the future, e-commerce operation assistant or engineering information officer?

E-commerce operation assistant is more promising, because there will be more room for this position to rise. E-commerce operation assistant can be promoted to the position of e-commerce operation manager or director in the later stage. These positions have considerable income and high commission if they operate well. As for the engineering information clerk, this position will be easier to get started, but the work content is relatively fixed, so the promotion space is very limited.
