We often see CVs where people have put down their reasons for leaving against each of their jobs.
This is generally unnecessary and can be counter-productive.
During an interview one of the main conversation points is going to be the reasons behind your career moves and if it’s all written down then you’ll have nothing to discuss!
If you’ve been made redundant from your last 2/3/4 roles, then writing this down may actually prevent you getting an interview in the first place.
Remember, a CV is designed to get you an interview so you must avoid giving the reader any reason for not seeing you.
