I am a working professional designer and thought I could earn some extra money from Upwork. The clients are generally terrible at communication. Countless people have accepted my proposals, wasted my time with back-and-forth emails, etc. Only to disappear and never be heard from again. In addition to the low quality clientele, the site is over saturated with mediocre, untrained awful freelancers. Upwork is garbage and I will never waste my time with them again.
