Suppose you are good in data entry. Now , what should you do in odesk? Will you start applying for jobs just after sign up? No! don’t be confident so much.
Odesk means you have entered in a new world. So don’t be hurry. Don’t apply for jobs after 5-6 days of sign up. Why you will not apply for job? Will you just wait to see , what is happening? No, you have to search to understand every things from the Odesk. Just visit the others profile , who are also working for Odesk from before. Just try to increase you profile as others. The more you browse odesk, the more you will learn. Then try to give test related to your profile. (e.g. Data entry). If you have any certificate , publish it to your profile. Just try to build you profile as others profile who already working in the same topics. Then you have to browse the several menus from the Odesk website to see what others services available for you. And how to withdraw money etc. Some of people, who have already registered for 6-7 months but still do not know how to withdraw money.
After 6-7 days now you can apply for a job. Just apply to multiple jobs for those topics, to which you are most experience. Otherwise you will get negative points.
