Getting a job can be hard. There are bound to be others who are interviewing for the same position. You need to find a way to stand out and be noticed so that the interviewer will take at least a second look at your resume. One way to do this is by writing a thank you email for your interview.
Time is of the essence
Write your thank you note within 24 hours of your interview. Do it sooner if you hear that your interview mentions that the decision for the position must be made soon. By writing the note so quickly, you help to make it plain that you really want the job. You also demonstrate that you possess good manners. This can be important as well. However, if you do not want the job, the thank you note could be a way for you to gracefully bow out of the interviewing process. You can then focus your energies elsewhere.
What to include
When writing the thank you note or email, make sure that you include any questions that you might have about the position and which were not addressed during the interview. The fact that you may have these questions is fine. The fact that you include them in the thank you email helps to demonstrate your seriousness. Include any information that you might have wished to include during the interview, but did not get to. This could be additional information about previous positions that you may have had. Include any follow-up such as "information the employer may have asked you to provide after the interview." Remind the interviewer of your qualifications and experience and why you think that you would be a perfect fit for the job. If you are not certain how long it might take before you will hear from someone regarding the position, include a request for that information in your email. When you have written your letter, read it over several times to make sure that it is perfect. Silly and careless typological errors can rob your letter of its intention.
If you have not heard from the company a week after you have sent your email, send a follow up email. This will help to further demonstrate how serious you are about the position.
