📋 Preparation Priorities (Key Areas to Clarify):

• 1. Blaming past cross-functional partners or management for project failures.
• 2. Showing an aversion to getting hands-on with tactical execution ('that's below my pay grade').
• 3. Lack of familiarity with modern API design or SaaS business models.

✨ Recommended Role Alignment Hook:

I've consistently scaled high-throughput systems and operational workflows by treating internal complexity as my problem to solve, not the customer's.
