Job search is NOT one-size-fits-all.
What I mean is that a single version of you does not fit every job that you apply for. Whenever you can, present the version of you that best fits the job opportunity.
To do this, first you need to identify what the hiring company is looking for by carefully thinking about the company and the job opportunity. What characteristics are likely to make an applicant particularly attractive to this company? Think about skills, experiences, interests, and accomplishments that may be relevant to the job you’re pursuing and what you know about the company. You may have to dig for some of this information, but it’s worth it.
Once you’ve identified these characteristics, carefully consider what you have to offer that makes you an appropriate, and hopefully the best, applicant. Take these characteristics that you have to offer and describe them in the form of personal accomplishments and achievements. With this information in hand, you can now customize your personal marketing effort for this job, presenting the version of you that best matches what the hiring company is looking for.
Customizing includes revising your resume to highlight your achievements, skills, and other characteristics that are highly relevant to this job; preparing a cover letter that demonstrates your interest in and ability to perform this job; and preparing to demonstrate the same things in a personal interview.
Job search is more competitive than ever before. Most jobs have many applicants and employers have the luxury of choosing the very best. A generic version of you is not likely to be the most attractive applicant. For success, you need to customize your personal marketing efforts to each job that you pursue.
