The first place that you have to show your communication skills is through your cover letter and resume. This is the place where you basically ''sell'' yourself. This is where you show all of your potential employers out there what you are made of. It is where they will gain their first impression of you. To make sure that their first impression is something that you would like for them to have, it is important to make sure that you are going through your resume and cover letter with a fine toothcomb.
You need to realize that many resumes pass over the desk of the hiring manager. Only a small percentage of the resumes that come through a business on a yearly basis make it through to the interview process. And then even a smaller percentage is given a job offer. If you want to be one of those in that super small percentage that gets a job offer, you must make sure that you are being proactive and doing everything that you possibly can.
You must show in your resume that you are serious about finding employment, not just in general, but specifically with their company. This may mean that you will have to specialize and adjust each resume that you send out, but it is worth it. Instead of a generic resume, you want to make sure that you are showing a particular interest in their company and the specific job title that you are after.
Another area to put a lot of thought and consideration into is that of the interview itself. Once you find yourself scheduled for an interview, it is important to make sure that you begin researching facts about the company, including their general history. The more you know about the company's history, what they do, what their market is; the better shot you have at getting the job. When someone shows that they have a vested interest in the company and that they are able to show that interest through communication in an interview, they have a great chance at getting the employment that they are seeking.
A follow up call, letter or email after the interview is another way to show off your communication skills, your interest in becoming part of the company and your personality. You want to be someone that they have always wanted to join their company. You want to be the solution to the employer turn over problem they have had. You want to be the person that they are chasing after, even though you have been chasing after them for so long.
While it may seem like a lot of work for a career or even just some random job, it is important that you stick with it. You want to make the most out of your career and you can do so by showing off your effective communication skills during your job hunt.
