2. These two certificates can be taken by college students. If you don't work after taking the securities qualification examination for two years, you must participate in the training organized by the securities industry association. These two certificates are valid for life and will not be cancelled. You can get a first-class certificate through two courses of securities qualification certificate, and a second-class certificate through all five courses.
3. Undergraduate graduates can only enter the securities industry from the account manager, and the first-class certificate is enough. If you don't want to enter the bank, I suggest you take the securities qualification certificate, whether you have never entered this industry or not, it will be helpful for your future investment. Of course, if you want to take the exam, just report directly after graduation. There are five courses in this course, which is very difficult to learn. If you pass the exam, you can engage in the securities industry and banking.
4. Both industries are verified after employment. For banks, it doesn't matter if there is no certificate. The certificate can slowly pass the basic exam and then+1, either door can be used, without having to pass all four doors. I usually take two exams in one breath, and it is not difficult to review them carefully. After passing, I will send you a certificate. It seems that this certificate has a validity period of about two years. You have to apply for it yourself.
5. Because of the industry norms, securities need to be verified, whether it is the basis of+1 or +N, or the subject of+1 according to your job requirements. After passing the examination, you have a qualification certificate, but you can also take the post first and then take the exam. It seems that you are not very interested in certificates.
