Writing a thank-you letter after an interview is always a good idea. Some employers think less of interviewees who fail to follow-up promptly. It's easy to follow up after an interview with an email, note, or formal letter. Taking the time to do so will help leave your interviewer with a good impression.
Thank-you letters allow you to sell yourself as a candidate. You can reference specific questions that may have come up in an interview. Use your thank-you letter to highlight the ways your skills and experience are a good match for the position.
