If you find a project interesting, you place a bid on that project right? Then you send a private message [PM] to the employer. You then wait for the buyer’s response.
Now, service providers [especially new ones] get excited if the buyer respond and ask that he is interested in hiring you.
Service providers then [most probably] respond with a thank you note. Buyer accepts the bid and then it is the service provider’s turn to finally accept the offer.
In between the above mentioned process, there may be some kind of communication between the buyer and service provider about the project details. But that conversation is just about the partial project details [most of the time].
If you want to be successful at freelance sites then I suggest you wait for the right project. Don’t accept any project if you do not know each and every detail about it. When you send the first PM to the buyer, I suggest you also ask him or her to send all the details about the work to you.
In the first PM, the buyer [most probably] will not send all the details, but at least you will get an idea about the work. If you think that you can do the project then ask the buyer to give you the complete information about the work. Tell him/her to send all the instructions or requirements so that you can make sure that you will complete the work in time.
Buyers do not mind to send the details: Buyers too want to make sure that service providers will complete the job in time.
