Jeffrey Selingo has done a solid job in explaining perhaps the most basic skill necessary for a successful job search: Writing.

Irrespective of the reasons why the skill level cited herein is what it is, as applicants compete with hundreds of others, it's important that you take control of your communication skills and the way you present yourself to potential employers.

From a hiring perspective, whenever I see a letter or resume that contains spelling, grammar, awkward structure or other errors, I move on to the next candidate. Others hiring managers in similar situations have told me they use the same approach.

Conversely, a well-written, concise presentation always receives my full attention and holds my interest.

There are myriad online, adult school and community college courses devoted specifically to improving these writing skills, separate from the employment search process. It is worth your investment in yourself to strongly consider this as it is an investment that pays off for the rest of your career and life.
