You probably mean “job objective”. (How did you end up writing it incorrectly — where did you get your information from?) It’s usually best to be specific, so that the employer will understand why you want to work at their company. If your objective is too general, they’ll think you’re just desperate to find a job and anywhere will do. Secondly, make sure you state your objective with your prospective employer in mind. That is, when they read your objective, are they going to see how it benefits *them* to hire you? Additional information can always be found by running a standard web search (terms: resume CV objective) on your preferred engine. Feel free to contact me with additional English-learning questions.
