Answer:
The correct answers are letters "A", "D", and "E": Use a business letter format; Send a separate letter to each interviewer; Mention something you liked about the interview.
Explanation:
A job interview does not end after leaving the prospective company where you could work. Most organizations decide to choose one applicant over another if they contact their interviewers after the interview. For that purpose, that last contact must be a formal letter stating what your impressions are of the company and why you are still interested in obtaining the job position. Besides, if there was more than one interviewer, a unique letter should be addressed to each of interviewer.
