first impression
Searching and applying for jobs is not enough to ensure land the job. You must make a good first impression in order to get the job, and in most cases you are going to have two opportunities to make a first impression to a potential employer.
The first, your cover letter.
Your cover letter is essentially your “on paper” first impression. While your resume gives information of your skills, experience, and accomplishments in the work force, a cover letter is more personal. It will still give information on your skills, experience, and accomplishments, but it will be written as a letter, which means it can also give your potential employers a glimpse into your personality. Of course, it must remain professional in order for you to be considered a serious candidate for the position, but feel free to let your personality seep into your cover letter, and finally, be sure to let the employer know the value you can offer the company.
The second, your interview.
If your cover letter and resume have done their job, then you may be asked for an interview. This is your real, in person, first impression. If you want the job, then the impression you make at the is the so  important. You must look professional, smile and be cordial with everyone-from the receptionist who greets you to each individual member of the hiring committee. Your potential employers are not looking to hire a robot. They want to hire a person who they can work with and who they can see working well with the rest of the company. Be personable and be yourself.
Making a good first impression in your cover letter and your interview will help you land the job and start on the path to a successful career.
