I also took part in this kind of work when I graduated. I didn't think too much at first, because I thought I just graduated. I haven't done it for a long time, because I feel uncomfortable calling to invite customers, no matter what. The market is a bull market, always losing less and earning more. If it is a bear market, it's hard to say, isn't it? In short, personally, I don't think this can be a lifelong career.
My advice to you is to go to a securities company and set up a small backstage or bank-securities link first. After a long time, you will naturally get better.
Finally, I tell you (I hope you don't get angry) that the "small securities company" you mentioned is not a securities company at all, but should be positioned as an intermediary or consulting wealth management company.
Hehe, I hope you can adopt it.
