How to Avoid Bad Rating in VWorker?

 In Freelancing sites like VWorker (formerly RentACoder), workers are judged and evaluated based on a feedback/rating model where employers rate the employees for each project they work on. The aggregate of all the ratings given to an employee (freelancer) determines how organized, professional and efficient an employee is. Most of the employers choose those freelancers who possess strong rating and a good feedback on their past projects. 

 Getting good rating on VWorker like sites is a trick and some workers fail to get good ratings and feedback even after doing good work. Here are some very important and useful tips for online workers who work on sites like VWorker:

• Remember that you communication with the employer matters a lot. Always make sure that you understand all the project details before starting work on it. This will make sure that your deliverable meets the requirements and isn't something which may cause some conflict between you and your employer. Projects which end with a conflict and arbitration often lead to a poor rating. 
• Make sure that you take a good care of tmelines. If you fail to deliver in time, chances are that your employer will rate you poorly and also won't be giving you any future projects.
• Always do a very organized and strong effort estimation so that you know very well how much project is going to cost and how much time its going to take. If you start blaming about low income or low budget after winning a project, employer won't entertain you and will rate you poor. 
• Remember, if you complete one project with an employer on VWorker like sites, chances are that he or she will award you more projects. However, it has been observed that if for any reasons you don't accept a new project from the employer, he may rate you poor for the project which you have completed. In such cases, of course you can't do anything except requesting him not to rate you poor for the work which you have done prior. 
• Never opt for tasks which you can't do. Always be in your professional and skill limits. Bid on only those projects which are easily manageable for you.
