Maybe your resume doesn't need to be analyzed, but most people only update their resumes after they've already lost their jobs. Your last resume helped you get the job you have, but it may not be enough to help you get a new job. Along the way, you have gained some experience and new skills that need to be added to your resume and skill set.
Resume Analysis helps an individual focus on strengthening how their resume represents them. In today's market, job responsibilities increase and change often. An updated resume should be aligned with the current market. Another way of thinking of your resume is that it may be an accessory that no longer works with your current lifestyle or mindset. If we consider how quickly fashions change, and how often we must update our wardrobes, our resumes probably need to be changed just as often.
It's a good idea to have your resume looked at by a professional career coach or resume writer.
