Everything that you do, every letter or phone call that you make is a representation of you. Because of this it is important to invest some time in developing a tool kit of job search resources that you can use. Also, it is important to go through a variation of a branding process that will assist you in creating an image that will be appealing to employers.
Branding is a way of distinguishing yourself from competitors. The font, paper, language, colours etc. that you use will assist in creating, in the employers mind, a picture of who you are. You want to ensure that this picture is true to you and is tailored to the job/industry that you are hoping to enter. Essentially, your resume, cover letter, and contact cards are your advertising campaign, so you need to take time to think out your strategy, who your target market is, and what your end goal is. Once you have figured this out creating the materials will be easier and there will be consistency in the message/image that you present.
