Brushing the cv up. I currently list jobs going back to 2006 on my cv and although they're in the same field they are are mostly junior roles that aren't really relevant or necessary to know about now.
The only thing making me think I should put them on is to firstly avoid any gaps between school and the first more senior role and secondly because they are for multi National big well known corporations so not sure if I'm down selling by not including them.
