They are fast-paced and allow little or no time for small talk. Directors are very time-sensitive, so never waste their time. Be organized and prepared to work quickly. Get to the point and give them bottom-line information and options, with probabilities of success, if relevant. Give them written details to read at their leisure.
Directors are goal-oriented, so appeal to their sense of accomplishment.
Stroke their egos by recognizing their ideas, and subtly reassure them of their power and prestige. Let Directors call the shots. If you disagree, argue with facts rather than feelings. When in groups, allow them to have their say because they are not the type who will take a back-seat to others. With Directors, in general, be efficient and competent.
