A salesperson would take a different approach to searching for a job than most people take, especially in the current jobs market. Many people simply submit applications and resumes to as many companies as they can, the “logic” being that odds are, one of them will call back to set up an interview. The problem with this approach is that you may end up with a job you hate. Some people mistakenly reason that a job they hate is better than no job at all, but this is not always true. Besides, times wasted applying for jobs you are either over or under qualified for could have been spent positioning yourself for jobs well suited to you.
Think for a moment about the process a typical salesperson follows, and you will gain some fresh insight into how to approach your job search. First, they approach the prospect and attempt to determine their needs. Then, they figure out how they can meet those needs and present their solutions to their prospects. By following a similar approach in marketing yourself during your job search, you will enjoy a much higher success rate than you would have if you had engaged in the more common (but less targeted) “scattered” approach. To borrow from the vernacular of the sales profession, you will “close the deal” far more often this way.
Sales people track their success in a different way from most other people, too, and you could probably learn something from that as well. For example, they measure the number of calls it takes to get through to a decision maker. For you, this might take the form of the number of resumes emailed. Next, they measure the number of appointments it takes to make a sale. Of course, in your case, once you have made your first sale, your job search has come to an end. At least, it should have. If you have only sent resumes to companies offering jobs well suited to your skill set, it will have.
Sales people also evaluate their approach when it is not working. You should do that, too. It could be that your resume is missing some important keywords that it should have. Perhaps your cover letter does not adequately convey the true depth of your desire to work for the company to which you are applying. Fix these problems promptly, and your successes rates will improve.
