After a job interview there are several ways you can keep the potential employer's attention on YOU as the likely person to hire by doing the following:
1. Immediately write a Thank You Letter to the interviewer. Write it right after the interview, and get it in the mail the same evening so it arrives in the next day or two.
2. Send a Follow Up Letter soon after that, if you do not hear from the interviewer within, say, a week.
Below is a guideline of how a thank you letter should be written.
In the first paragraph, thank the interviewer (or express your appreciation) for the chance to meet with them to discuss the job and see the premises (use the term "meeting" rather than "interview" if it seems appropriate). Make some reference to your positive impressions of the company.
In the second paragraph, offer some new information or additional reason for the employer to be interested in you for that job-perhaps a "goodie" that you didn't mention in the interview. (You might even link this new information to a problem or opportunity the company is experiencing.) Repeat the job title you are applying for, and show continued interest in it.
In the last paragraph, let the employer know (graciously) that you expect to hear from them again and "plant" the idea in her mind of a phone call to you. Make it clear you're willing to come in and discuss the job further, if necessary.
