I love to write recommendation letters. It’s an everyday application of my fascination with biography. On occasion I read reference letters that don’t do what they could to make an individual stand out from the pack.
Two simple tips:
Emphasize the distinct capabilities that the letter’s subject offers. People hiring for lower-level jobs may want information about the candidate’s punctuality or cheerful attitude. For a senior position, paint the portrait of a person who is more than merely well-behaved. Is she a rapid learner with an encyclopedic memory? Say that rather than calling her “resourceful.”
Give a narrow enough recommendation to be credible. Saying that your former subordinate or coworker “can do anything” is largely a comment about attitude not about skill or talent. Instead, provide a strong endorsement of his ability to recruit top talent or deliver critical training programs effectively.
