- understand as much about the product as possible, primarily from a user point of view

- meet as many different verticals as possible and understand how they work

- speak with all other senior PMs and tech leads and understand their workflows

You're going to be working with multiple teams and stakeholders and it's crucial you have a mental map of how everyone's workflow is. You also will have an 'outsiders' view for the first 30-90 days as you look at the product with fresh eyes. Use this to drive insights for the product if applicable.

Lastly, don't ever stop customer meetings. It may not be on the agenda for other Senior PMs, but don't let that stop you. Customer meetings will keep your insights fresh and valid.
