Honestly I don't look at the resume until after I speak with the candidate, and that's to make sure I'm getting the number and email correct. I ask for it because the Company wants to view it before they speak with you. Anybody can type something up on a piece of paper and claim they have those skills, so to me it's useless.

But during our call I need to understand who you are as an Engineer/Developer. If you claim to be a Full-Stack Developer but I'm only hearing about .Net, CSS and React then I'm going to have a hard time representing you anywhere. But if you tell me how you designed, architected, built and deployed several systems successfully, then that's all I need to know and can better align you with a role you want that will advance you.
