Won’t the employer think that an applicant is desperate if he/she sends a thank-you letter?
Of course not. Rarely is an employer not pleased to receive a thank-you letter. It is considered as a common way of showing politeness, a gesture of courtesy, and a way to keep your name upfront. In fact, because so few applicants think to send a thank-you note, you’ll more than likely outshine the rest of the interviewees.
