How can you do all these?
Start by managing your CV. You can find a drop down menu at the left top corner of Monster's site, once you have logged in. Click on Manage to access the CV managing menu.
If you haven't uploaded your CV you can easily do it or you can create your resume using Monster. Both options are available.
Once your CV is uploaded you can manage its settings. Just scroll down and fill in whatever you think is necessary.
Once your CV is uploaded, some settings are filled in automatically, like the location you are looking for a job. Other working locations can be selected once you have chosen that you are interested in other locations.
You can use the boxes for selecting the country you are willing to work. Remember that you'll be asked whether you are allowed to work in this country. Make sure you have found out about this in advance.
Be aware that you can upload several CVs. This is wise for uploading the same CV in different languages and making them available in different countries. For example, it is most probable that a France employer will ignore a CV written in Greek.
