Other misconceptions include the use of an objective on the resume and writing detailed job descriptions. A job objective is usually a statement of what the candidate would like to do or the specific job they are seeking. The reason why this is not needed is that the cover letter should express interest in the position and there is no need to state it again. In addition, many objective statements are so specific that the candidate would be ruled out from other potential positions that may be related to the advertised job. In addition, many jobs I have seen listed on resumes includes wording that either came from job descriptions or have been written like standard wording from these types of descriptions, and that doesn't necessarily explain the skills the candidate has and may contain jargon that is not easily understood by everyone reading it.
But most people wait until a resume is needed and it is at this time that a decision is made to try to refine and update it, or leave it as is and hope that it will be sufficient enough to gain a recruiter or hiring manager's attention. There is a misconception that because resumes are rarely mailed out any longer, they are not that important. Yet many online application forms still request that a resume copy be uploaded for review.
In order to get a good job you must communicate to the employer that you are ready, willing, and able to do the job. So if you are capable of producing a top notch job resume, you definitely increase your chances of getting a better job.
You have to keep in mind the fact that when you send out a resume it is taking your place and represents you as a person, without the guarantee of securing an interview - and that means your resume can make or break your job prospects before you ever get to speak to someone about it.
