A challenging question won’t undermine your confidence if you have a plan.
Making a presentation under the best of circumstances can be nerve-wracking. From worrying about whether the rest of your team is as prepared (or unprepared) as you are, and making sure that the technology works, to confirming that your stories resonate, and that you actually remember what you had planned to say, speaking in a group setting can make even the most confident leader feel apprehensive.
And what can make a presentation even more unnerving? Fielding hostile questions from the audience. These aren’t innocent informational queries (like “Which agency are we going with for our next campaign?”), nor are they speculative requests (such as “Who do you think will be our biggest competition in three years?”).
