You can get content writing jobs a few different ways. It’s best to reach out to companies directly or to apply for freelance content writing positions that are advertised on websites like Indeed.com. Applying to posted calls for freelance writers can be a good way to know which companies are looking for new writers. However, companies that post these ads end up with hundreds, if not thousands, of applicants, which can make it difficult for new content writers to obtain their first clients.
It can help, but other degrees also have content writing value. For instance, the ability to synthesize and relate complex information is key to content writing, but can also be acquired from studies in education or philosophy. Companies that offer content writing positions tend to find it easier to train someone in a complex topic than to train someone to write, however. For example, as a healthcare professional with mediocre writing skills, you're less likely to be hired as a healthcare content writer than a strong writer with no healthcare background (but who can be trained in healthcare topics).
