I used to ask myself the same question but I'm finding out that a high percentage of the job opening for senior career job seekers with 20 or more years of industry experience typically go unadvertised. Company's use a very different recruiting process for those positions if they choose to recruit outside of the organization; and that's a big if! These are very limited jobs openings with a large candidacy pool so the competition is high. What's the specific feedback your getting from your job applications?
