To enter the financial industry, at present, it is ideal to enter the banking and Internet modes. I am not optimistic about the prospects of securities companies, wealth management companies and futures companies. I think it's safer for you not to leave your present job for the time being, and at the same time, take the time to do it and look for future opportunities. The only regret is that you have no relevant work experience. After all, you are engaged in the machinery industry, and the industry span is large. The only chance lies in the marketing job you are doing now. Banks also need talents in marketing. You should make up your financial knowledge and seize the opportunity to get ahead in the future. There is still a chance. In addition, I think your college degree is also lacking. With all due respect, I think you can also take a self-taught undergraduate diploma (major in finance) with a degree certificate. It will be more beneficial for you to transfer to the financial industry in the future.

Finally, I wish you a successful career change.
