What would be the skills qualities and interest that the virtual assistant must have?

It depends on what you are looking to do as a virtual assistant, or if you are looking to hire a virtual assistant. Everybody has a different level of skills, and not everybody can do everything. That being said, there are virtual assistant companies, such as BizEBee Virtual Assistants who have a team of virtual assistants who have a variety of qualifications. This way there is always somebody who knows how to do the task. If you are looking to be a virtual assistant you should focus on your current skill set and build on it. For example, if you are great with administrative work, there are people looking for somebody to do that for them. I hope this helps!
