Understanding Updates from Company Table to Contacts Table

Hi - Brand new and I feel like I am missing something very basic. I have a company table that then finds people and creates a second table from the imported profiles - that all works perfect! I also have a watch for new hires event which I want to then make sure those new hires are in the contacts table. My question is - will the contacts update from the company on my refresh schedule or do I need to use send data to table from new hire alerts --> contacts
