Hi Nissrin, one thing I would add to the above comments which are all great, is to find some organisations you would like to work with and contact them directly, about gaining work experience.
If you are coming from a background where you ready have a lot of experience, it can be helpful to do something beyond your CV that shows particularly what transferable skills you have developed. An example of this might be a spreadsheet.
When you contact organisations to ask for work experience you may want to share this spreadsheet with them.
