A cover letter is a single page document that briefly introduces yourself, generally explains your purpose of applying and precisely highlights your outstanding experiences and skills, which will help you enormously with your job application, even future career.

Editing a cover letter may be not the same and that easy as fixing a page of your dairy. Instead, it turns out to be painfully difficult to figure out a distinguished cover letter since there exists an unbeatable fact that first impression counts a lot and your cover letter is the first thing that comes into those hiring managers’ view. A great cover letter may make your resume more eye-catching and is a clear-cut summary of your excellent experiences that may qualify you a high chance for assuming the position.

Ensuring your cover letter in good shape will also render you much help in appealing to managers' attention. Although only one in two letters will get read, there is a still 50% chance you could grasp. And you’d better seize the opportunity of making yourself distinguished.

First, it would be better to choose a comfortable font size and font style for the sake of hiring managers. The former should better go up a 12-point font and the latter should be more professional to present a stronger cover letter.

Second, you'd better leave some room for your one page cover letter and try not to make the contents crammed together, which may make hiring managers get annoyed and your cover letter may get passed directly.

Although it's not just a piece of cake but quite tough to write an effective cover letter, you should go all out to provide hiring managers with what they are looking for.

First of all, you should do much research about the company and the position you are willing to apply for beyond simply reading job description. Knowing more about the company, her culture, advantages and challenges for instance, will help you make up your minds on how to set the right tone in your cover letter.

Second, begin your cover letter with your specific contact information and never waste words in your cover letter. Avoiding starting your cover letter with "It's such a pleasure to apply for the job I have seen..." but beginning your cover letter with the punch line "Why this position is engaging to you and why you could qualify the job" will increase opportunities for hiring managers to have a look at your cover letter. You should better keep from writing common platitudes and say out your opinions directly, such as "Before you read further, let me give you two reasons to explain why you may hire me..." What's more, you should also mention it on the first paragraph of your cover letter if someone you know worked there. And putting yourself in the hiring managers' place will make you know better that the appellation "Dear Sir or Madame" is so much old-fashioned. Therefore, you should acquire those hiring managers' names from people you know who work in the company or from the Internet.

Then, you shouldn't hesitate to present all your personal values. Your excellent experiences and skills will help you a lot on getting the job for they are valid proof of your personal values. Moreover, people who get the ideas of how to solve problems the company has encountered are ones that hiring managers have always been looking for. Based on information of the company you have collected during the research, you'd better make known that you know exactly what problems the company is facing. You may write this in your cover letter "A lot of Internet companies are cutting sown their employees and consolidating with other companies because of the fierce competition." and then tell them how your past experiences have equipped you with the qualification of solving similar problems.

Moreover, you should show enthusiasm you are holding on the position, which signifies your personality a lot. Being mature and professional will give you extra points among other appliers. In addition, simple is the way for you to go for hiring managers are much more likely to read an open and shut cove letter rather than an expatiatory one.

At last, you should make some indications that you are willing to get interviewed, will be in contact with them if you are not informed by them and give your thanks to them for spending time on reading the cover letter.
