If you go on a platform like Upwork, you may find already reviewed contractors. You may look at their work history, real life work experience and other profile details to make your decisions. I work on Upwork as a wikipedia page creator and have found that many of my newer clients usually search for the tag line and basic profile summary rather than work history - so it may make sense that you would like to hire those without a great work history on the platform itself as they may also be mentioning, *real life* experience and off platform experience which may lead you to hiring them on the same platform.
