I just started today with freelancer.com and found out that they are charging for all sorts of ridiculous fees: tests for Basic grammar test (US), Basic grammar test (UK), basic arithmetic, advanced arithmetic treating us like little kids. Worse part is you have to pay them $10 per month to be eligible to bid on some of these projects. Customer service is nonexistent as they don't give phone numbers and is relayed via a robot.
Hi, Thai. Lara here from Freelancer.com. Yes, there are paid exams on the site which help freelancers maximize their potentials. In addition, some employers require freelancers to pass a certain exam before they choose them for a project.
As for the $10 USD per month, the only fee that is being charged monthly is the membership fee. If you have any concern regarding the fees, you may refer to this link: https://www.freelancer.com/feesandcharges/; or feel free to send me an email at larao@freelancer.com. I will be more than happy to check your account for you. Looking forward to hearing from you soon.
