I loved the suggestion made quite some time ago (can't remember the thread, or exact wording), when discussing automated rejection letters, that if we are ever in a position to reject an interview/job offer we should give firms a taste of their own medicine, and reply with sth like:"Thank you for your interest in my profile. Unfortunately, due to the high volume of interest in my skills at present, I am currently unable to accept your interview/offer. Please do not hesitate to contact me again in a couple of years when your offering may be more closely aligned to my aspirations."I remember it 'cause I spilled some tea on myself with the laughter. Quality stuff!
