The question is how do you write one and what is the right way to go about it?
Some job applicants feel that it could be perceived as a sign of desperation or that they are trying to molly coddle the interviewer. Far from it, most employers are happy to receive a thank-you note. It is common courtesy and good manners to do so.
There is no ideal format for a thank-you note. Just tailor it to the culture of the company and the type of rapport you developed with the person who interviewed you. If the person was reserved and formal, send a formal typed letter, on the other hand if the person was jovial, cordial and exuded warmth and kindness add a personal touch to the letter and send him a handwritten one.
However, just make sure that your letter is not shoddy and full of typos, badly spelt words and grammatical mistakes. Spell check and proof read your letters.
I am posting a sample letter, but be careful that you use just the basic structure and not copy it verbatim. Just keep in mind, that through your letter you are showing your appreciation for the interviewer's time and effort.
