"They asked me to hire a PM to help communicate. So I did follow their suggestion. The PM's english skill was better than the developer but still inadequate because we still have communication problems with each other. During the contract, I did verbal and written communication for the initial scope, roadmap and test task. Even with the PM's help, the developer still didn't understand. PM misunderstood when I said "their suggested solution was incomplete because it didn't consider other impacts and relationships." He thought I changed the scope. After two weeks of the trial period, they couldn't deliver. So I ended the contract to not waste each other's time and resources."
