First of all, I think enterprises are more important than industries, because many enterprises are undergoing rapid transformation and there are many phenomena of cross-bank operation. As long as the internal culture and strength of an enterprise exist, even if the main industry declines, the enterprise can quickly transform, and many multinational enterprises have had the experience of transformation. From this point of view, choosing a good enterprise is more important than a good industry.
Of course, if you like a certain industry very much and especially want to take root in it, then the enterprise is not so important, because you can jump ship, and it is easier to jump ship in the same industry.
secondly, the sales assistant doesn't want to do sales, which is more difficult. From the development of sales assistant's career, it is inevitable to experience the sales stage personally. If you don't engage in sales, you may consider the administrative direction for future development, but you can't discuss it further without knowing the reality of your company. It doesn't matter if you don't know about the medical equipment industry. As long as you are willing to know about it, it's easy to get a basic understanding. The main way is to learn from the industry website, digest a lot of consultation, and ask more experienced colleagues.
finally, regarding your confusion, we really can't give you an accurate choice. The above suggestions are for reference only.
