Yes Virginia, there really are legitimate work at home opportunities! Not only that some of them actually have company benefits. Companies like Buffer, GitHub, Zapier, and even Apple offer full and part time positions in specialties like computer technology, customer service, coding, graphics design and account management.
These are real jobs so you have to send in a real online application and go through a real hiring process. You must demonstrate knowledge of the skills required. You must have a good work history and have job experience in many of these postions. Jumping through the required hoops is worth it however, as these look good on your resume and can lead to even better telecommuting opportunities.
