If you are very demanding on your resume and don't know what to do, you can actually find someone to do it online. I know a very professional online studio called You Yi Zuo, where I worked before.
Supermarket promotion only sells things to manufacturers.
General salesmen are rarely promoted by promoters, because the company's work level is not a promoter. Unless you have a strong personal ability. As for the performance mentioned by the friend above, even if the performance is good. Everything in your company is attributed to the salesman, which has nothing to do with you.
The quality of performance, to put it bluntly, does not mean that you will sell.
If the salesman has the ability, he can ask the supermarket supervisor to adjust his post and increase the number of rows.
Be a promoter. Apart from contact with salesmen, there is almost no contact with people in the company.
Promoters are equal to waiters. There is no more skill to operate. It's simple, you can't learn anything except recommending products to customers. It is completely different from the concept of salesman, who runs stores, applies for positions, talks about factory activities and forms communication with supermarket supervisors. These have nothing to do with the nature of the sponsor's work.
