Ongoing collaboration
Sinthiaâs work was okay, but it needed substantial revisions and repeated back-and-forth that often felt like going in circles. I also found her very pushy about renewing with increasingly larger contracts. The constant pressure to spend more made the collaboration uncomfortable, especially while the work still needed improvement.
