When you start applying for jobs, and face competition from other candidates, who do you think gets the interview? Is it the middle 50%? The bottom 20%?
I bet you're thinking the top 5-10 candidates are granted interviews, which in today's world of electronic resumes, could be the top 1% based on some of the numbers I've seen from hiring managers. It's not uncommon for a single position to get 300-500 submissions.
How do you position yourself to be in the top ten percent? I have on easy way that will help you along.
In my research over the last year, and in giving a presentation on the Modern Resume to hundreds of people, it's been fairly consistent in my audiences that about 10% of the people out there that come to these events blog as a part of their career.
And that's the 10% of people that care about their careers and are willing to work on them.
Just by doing a blog you can separate yourself from many other people. You give every potential interviewer or HR person more information, and more reasons to consider you as the top candidate instead of others.
Would you rather interview someone that has a large profile and you have an idea of how they think from forums and blogs, or someone that just sends you a two page resume summary? I've always believed that more information is better, and it helps you make better decisions.
HR people, along with managers, are getting smarter. They don't just hire based on MCSE credentials, or any others. They look beyond that, and the more comfortable they are with you as a candidate, the better image (read "brand") you present, the more likely you'll get the call back.
Now you need to write good blogs. Be simple, tackle things you know well, and have someone proofread your entries. You are showcasing communication skills, as well as knowledge, and keep that in mind.
