The secret to success is sincerity. Once you can fake that, you've got it made. Jean Giradoux
You, as well as the organization I applied to yesterday, state that one of your important qualifications is "a sense of humor." While I happen to think that I have an excellent sense of humor, I am baffled as to how to communicate that on a resume or a cover letter. I know that if I get an interview I may well be able to thrill you with my genuine wit and sparkling repartee,* but I need to get that interview first.
Also, upon further reflection, what does it mean about working conditions when you need a sense of humor to be successful? Humor takes you a long way in dealing with other people, especially in the workplace, but is yours so stressful that laughing is important to keep from crying?
Inquiring minds want to know.
