Pros
Fully remote.
People are pretty kind.
Good hourly pay.
Cons
Micro1 feels like working for the SEO content mills of the 2010s. If you get hired onto a project, you crank out tedious task after tedious task. Your work is edited and sometimes graded, which is belittling. Some projects have so many people hired on and inconsistently available tasks that people constantly have to refresh for hours or days hoping for work. And then act grateful or excited on Slack, when they should be angry that this is how they're treated. An hourly rate that's incredible when there's a few hours a week available is a joke.
You are also a contractor for each project, so once the project ends, you are done and have to scramble to interview and hopefully get hired on to another project. They clearly have no interest in the actual people working, they just need to meet their clients goals, and you will be a worker bee among thousands doing that for them. If you just want some extra cash, great.
If you want dependable income, don't go looking at Micro1.
