I’d take a different approach to your preparation:

Try to find videos of FB officers (Zuck, Sandburg) who have already been publicly grilled.

Most likely on a corporate level, FB employees already know how to answer and respond to most of these privacy questions.

That means you need to figure out their initial canned responses, what assumptions they’re building on, and prepare a line of questioning/reasoning to chip away at their logic in follow-ups.
