What are the things you consider (e.g. according to the CV), whether to move on with the candidate?

Yesterday, I asked for the best places/platforms to connect with talent for your team.

The next question is more about how you select or proceed in selecting the right candidate.

For example,...

When a company has to choose from 1,000+ resumes, what will differentiate that candidate and move them to the next round?

(If HR agencies are also in the process, I would also be interested in their procedure, because there is a difference when the founder selects and when someone external does.)
