If you are an employee of the securities business department, a general bachelor's degree is enough, and it is best to have a securities qualification certificate. But now the securities industry is depressed, and foreign recruitment is rare. Most of the employees in the sales department are old employees who have worked for many years, and the flow is not too big.
Securities brokers are generally supernumerary intermediaries hanging under the sales department, responsible for introducing customers, managing their own customers and getting a commission from them. The quality is uneven.
The recruitment conditions of customer service personnel are set by hr itself. If you really want to do this job, you should try to increase your experience in this field. For example, it is best to have practical experience in stock operation and then show it in your resume in order to get an interview opportunity.
