I will share with you my experience with that. After a long period of unanswered proposals I've succesfully landed my first job that required at least 90% succes score when I included an example of the needed product in the proposal along with some other refferences on my previous jobs. I've made sure that I have the relevant portfolio ready fot the jobs I'm after so the clients can easily determine that I can do the specific task. I went a step further with starting the job already and presenting the progress to the client in the proposal. That required speed and accuracy, and those are mainly the qualities most of the clients need. Now I rarely make my proposals like this.
Hope this was was helpful.
Hi Md Harun,
You can still submit proposals to these postings if you have the required skills and time to complete the job. Proposals that don't meet this preference will still be shown to the client.
