The level of experience required for online jobs varies based on the type of job. Most sales reps do not require a college degree, but some companies that sell specialized equipment ask that applicants have a degree in a specific field. Many online writers and editors have a high school diploma or its equivalent, but some companies require that writers have a degree in journalism, communications or a similar field.
The online application process for these jobs—or perhaps “gigs” is the better word, since they're all for independent contractors—is pretty simple and straightforward with very little required of candidates. Some of these opportunities—like the micro-jobs—you could very well apply and start the same day. And these jobs require very little commitment and can typically be done on your own schedule.
