Professionals are always on the lookout for a better career option, and rightly so. Because once a person gets too comfortable in a job it means that the job has either become too easy or that the person is not willing to push himself to the limits. A professional's resume is a very crucial one because it is written while opting for a transition. The resume should reflect the evolution in a person's career. Usually this will be written a few years into the career beyond the entry-level position. A mid-career professional's resume may go beyond one page. This will be used to elaborate on the recent work and professional achievements. The core list of competencies will be delved upon in this resume and it will make it possible for a prospective employer to know what the candidate is capable of. The resume should essentially tell the story of the candidate's career evolution and the responsibilities that he or she has had to undertake.
