I am career coach and love to help people get hired within in 6 weeks to 2 months from the day they start their job search. I used to be a recruiter and a headhunter for about 9 years. I like to give my clients hot tips that will help them get noticed in cyber space.
It used to be that 80-90% of the people that had success quickly in their job searches were heavily networked or really using their networks. Well those statistics have significantly changed over the last 4-5 years. Most HR professionals and Recruiters use the job boards and sites like this one to find great candidates.
So my hot tip that I always give is to make sure that when you post your resume on Craigslist.com, Monster, and Careerbuilder for example, that you make sure you make changes to your resume and profile every three to four days so you can always retain a spot at the top of the candidate pool!
Recruiters and Headhunters live on the boards and we only like to search for the last two days of resumes, candidates, etc.. I hope this helps. It's been guaranteeing my clients 2-4 live telephone interviewes a week.
