Initiated in Upwork proposals refers to the status of a proposal that has been submitted by a freelancer to a client for a job listing. It means that the freelancer has applied for the job and their proposal is now under review by the client. The use of cookies or similar technologies by Upwork and selected third parties is for technical purposes such as enhancing site navigation, analyzing site usage, and assisting in marketing efforts. When submitting a proposal, freelancers need to choose the 'Submit a Proposal' button on the job post page, set their hourly rate or bid on fixed-priced projects, write an introductory cover letter, answer any screening questions, and add attachments such as work samples. It is important to note that the majority of proposals submitted may not receive any response, good or bad, from the client. Therefore, freelancers should not give too much thought to sent proposals and should keep going until someone gets back to them. Winning the first job on Upwork can make the process easier.
