As a marketing communications assistant, your responsibilities are to support a company's marketing department with the optimization of advertising campaigns, brand awareness efforts, finding new clients, and tracking marketing metrics. Your duties may include assisting with corporate and internal communications, providing media relations, generating monthly reports for managers, and performing other tasks assigned by a supervisor. Some employers may ask you to interact with customers, verify the accuracy of information provided to you, work independently on small marketing projects, and coordinate training for other marketing staff. On rare occasions, you may need to work overtime or unusual hours to meet the marketing department’s needs.
