As an internship on the department of investment bank at Pacific Securities Limited Liability Company, I was primarily accountable for organizing information and writing files, especially the chapters concerning legal regulation in the prospectus and bond prospectus. In the process of writing the prospectus, good communication skills have enabled me to effectively understand the information and details of the listed company. As the representative of the intern group, I led six members to solve the problem that the company encountered during the process of listing. At the end of my internship, as a representative, I made a presentation within the company, and I was well received by my confident attitude. Through the internship, I can adapt flexibility myself to the competitive, high-intensity working environment.
