A letter rejecting a job applicant should

A) avoid explaining why he or she was not selected.
B) point out the applicant's shortcomings.
C) be as personal as possible.
D) be as long as possible.
E) offer advise on how to improve their interview skills.

It is generally not appropriate or necessary to explain why an applicant was not selected, as this can potentially lead to accusations of discrimination or bias. A simple, polite rejection letter that thanks the applicant for their interest in the position is sufficient.
