Give it a try - Avaliação de funcionários no cargo de Data Analyst na empresa DataAnnotation

Great to work for, lots of work once you get past initial assessment as a specialist for coding. Receiving payments is seamless.

Work can be tedious and require long blocks of time.

Easy to get set up and work through the "entrance tests", and fairly easy to earn through your first project. The pay per project is OK (in THEORY), but in practice it can be difficult to make real money (see cons).

My experienced was, unless you have expertise in a very in-demand area like STEM, multilingual, or teaching, the available projects quickly dry up. They then encourage you to "take more qualification tests to see more projects." However, after the tests are taken, no indication is given as to the results and at times nothing more shows up in projects. In the end it can be a random, and disorienting process.
