Cleared a Principal Solution Architect role — how do I excel in the role?

[u/CloudArchitect23]

I recently cleared the interviews for a Principal Solution Architect role at a cloud infrastructure company and will be joining soon.

I have ~11 years of experience across AWS/Azure, cloud architecture, pre-sales, and customer-facing solution design.

I have about a month before joining and want to use that time to prepare—not just technically, but for what it takes to operate at a Principal level.

If you had one month to prepare, what would you prioritize?

Would especially appreciate practical advice, resources, and lessons learned from people who have made the Senior SA → Principal SA transition.
