Students cover letter and resume only one objective, that is to get an interview. So your cover letter and resume to students is always around to write this purpose.

Cover letter should reflect your style, there are three purposes
1, with the style, easy to recruit staff left a deeper impression
2, highlighting a number of college students resume the things not mentioned, so that more students solid resume.
3, giving recruiters respect, that it took time to prepare the students your resume.

How to reflect your style, there are several steps
1, the analysis you want to apply to companies and jobs, they need what kind of personality?
For example, you apply for planning your cover letter can not be too law-abiding; the other hand, your qualifications for the office staff of state-owned enterprises, they should look aging and prudent; you applying technology, we should highlight in your cover letter in the technical superiority, "that your ※ ※ company in the recruitment of talents, I think the more appropriate to this position because I am in the job requirements and the × × × × 4 years technical experience and successful project "

2, in turn, to consider whether the style matches your personality?
Of course you can "copy" of each kind of style, getting an interview, but you have to consider if your interview, test, and will not be five years after graduation, or something wrong with it? So, my suggestion is to analyze your own personality and tastes of good career planning and then to find the right company. Because there are a very good saying "leopard change its spots", and its hard to go to hide their original style, why not just start to choose their own good at business?

3, more specific, the proposed combination of the specific job to talk to candidates as well.
