Good business practice suggest that after an interview with potential employer, candidate should send after interview thank you letter. In this letter a candidate is supposed to express his gratitude to the employer for consideration of his application and to conduct the interview. After interview thank you letter could be send either as a thank you email note, or as a formal letter. The structure should follow the usual formal business letter, with a trivial personal note at the end. After interview thank you letter should follow the interview, and preferably is to be send by the end of the day when interview is held, which will help the employer to remember you better, and potentially increase you employability for
