A resume is a marketing tool in which the content should be adapted to suit each individual job application or applications aimed at a particular industry. The transmission of resumes directly to employers became increasingly popular as late as 2002. Job seekers were able to circumvent the job application process and reach employers through direct email contact and resume blasting, a term meaning the mass distribution of resumes to increase personal visibility within the job market.
Often, job seekers have a few mistaken opinions about potential employers. They believe that employers are able to easily separate the qualified job applicants from the less qualified applicants. But this is likely not true. Sometimes there are from 30 to 300 resumes for the same job. So the interviewer first does a fast screening of all the resumes to eliminate as many as possible. The "good" resumes usually make it through the screening process. Many times the best job candidate is screened out due to a poor resume.
Job Objective -- lets the employer know that you are interested in a specific type of work. This can be done in 2 or 3 sentences. Example: work in an analytical chemistry laboratory that focuses on environmental samples. Oversee and coordinate the activities of other lab technicians.
In many contexts, a resume is typically limited to one or two pages of size A4 or letter-size, highlighting only those experiences and qualifications that the author considers most relevant to the desired position. Many resumes contain keywords or skills that potential employers are looking for via applicant tracking systems, make heavy use of active verbs, and display content in a flattering manner.
