I used to work in a HR Consulting firm.. editing CVs was a core part of my job.
So many people listing EVERY job they ever had in detail.
Protip: prioritize jobs with tasks and duties related to the one you are applying for. If there are big gaps between these jobs where you worked in another career area, you can put these in, but they do not have to be detailed descriptions. They can even go in a separate section later in the CV.
Use the room you save to more thoroughly outline the relevant jobs.
Also list your most recent job first… do it in reverse chronology.
