(FORTUNE Magazine) – Dear Annie: I'm seeking a job with a company that had me speak with eight different interviewers, some individually and a handful of others over dinner. Should I send thank-you notes to all eight of these people or just the ones with whom I had formal interviews? Where does one draw the line? -- Georgia on My Mind

Dear Georgia: "Err on the side of thoroughness. Write to all eight of them," suggests Marjorie Brody, whose Brody Communications has advised executives at Chase, Citibank, J.P. Morgan, SmithKline Beecham, and elsewhere on polishing their people skills. She also wrote a handy little book, The 21st Century Pocket Guide to Proper Business Protocol (Career Skills Press, $19.95). One reason to risk writer's cramp: "It's an easy way to make people feel good about you." Besides, if one interviewer mentions your lovely thank-you to someone who didn't get one, awkwardness could ensue. They needn't be lengthy, just four or five sentences--handwritten, sent via snail mail--saying that you enjoyed meeting each of these folks and hope to work with them. Try to make each one a little different, including something in particular you discussed. (Here's hoping you've got a good memory or were taking notes.) While you're at it, don't overlook the informal power structure. If an interviewer's administrative assistant was helpful, mention it, or even send a separate note. Notes Brody: "These are people who have real influence, but who often go unrecognized."
