An executive assistant (EA) supports a high-level manager, CEO, or entrepreneur by managing their calendar, correspondence, and other administrative tasks. EAs are often responsible for the business side of a company, and they typically have more experience and tactical thinking than administrative assistants. 

Here are some responsibilities of an executive assistant:

• Calendar management
• Manage the executive's calendar, including scheduling meetings, appointments, and events. EAs must be able to prioritize tasks based on urgency and importance, and anticipate potential conflicts. 
• Communication
• Handle incoming calls, emails, and other communications. EAs may also write and edit correspondence, memos, and presentations. 
• Travel arrangements
• Manage travel logistics and activities, including accommodations, transportation, and meals. 
• Meetings
• Arrange and coordinate meetings and events, including booking meeting rooms and ordering lunches. EAs may also take notes at meetings and prepare the initial draft of minutes. 
• Research
• Conduct research, assemble and analyze data, and prepare reports and documents. 
• Administrative tasks
• Perform general administration duties such as filing, scanning documents, faxing, and tidying offices. 
• Confidentiality
• Maintain professionalism and strict confidentiality with all materials.
