Be positive! Above all in your job interview and writing your resume, you must maintain a positive attitude.
Leave out any negative or irrelevant points in your CV. If you think that the year of your graduation might subject your to age discrimination, then leave it out. If there are any tasks and duties in your current or past jobs that are not relevant to your present job search, don't include it. Also, leave out any irrelevant personal information such as your height, weight, religion, or race.
