There are no hard and fast rules on what not to put in a CV, it is personal preference. However, you don`t want to make your CV drag on and there is no point in putting any information that is irrelevant to the job. Here are a few tips on what not to put in your CV

Age, height, weight, marital status are not pertinent to the hiring process (unless you're applying to be a model).
Photos - the only people who need to include these are models, actors, actresses and possibly air cabin crew.

Salary details. An employer will always offer the minimum that they can get away with.

Any sort of failure - exams, marriages, businesses, etc.

Fancy binders, several colours, complicated graphics.

Negative descriptions, problems or gaps in work history which would cause the reader to have doubts about you. That is not to say you should lie, however it is far easier to discuss these issues in greater detail at an interview.

Reasons for leaving each job.

Do not use poor quality photocopies of your CV - they make it look as though you are sending off your CV to lots of companies and that you may not be too bothered who you work for.

Don`t list more than 3 referees - no relatives.

Good luck with any future employment
