I only know one ESFJ (confirmed type) - my receptionist coworker.
She's extremely dutiful, always finding something to do around the office, very bubbly in expression, makes a LOT of small talk with the people in the office (although, I don't think she would consider it small talk -- ex., telling everyone about the new car she's getting, what her dog did yesterday, about the party she's planning, etc.), very sensitive to smells (she walks around spraying the office with odor eliminating spray -- even if it's just the smell of someone's lunch), careful and serious about her work, very enthusiastic about a new deal the company has closed (and follows the "story" with all the details from start to finish), very clean and tidy (her environment and her way of dress), talks on the phone a lot with her mom and husband and gets upset easily by events in the newspaper (and follows the news consistently).
