Most of the time, it won’t be relevant to include every piece of experience you’ve ever gained. There will be things you have learned or jobs you have done that aren’t important for the role you are applying for.
If you have a lot of experience, focus on the areas that are most relevant to the role you are applying for.
For example, if you are applying for a role as a veterinary nurse, it probably isn’t worth mentioning the experience you gained during your summer working in a restaurant as a dishwasher.
