I’m sure it might help for cold contacts (HR first look?) and things like that, especially without a strong background/CV. But in my limited experience nobody cares if you’re good and good to work with.
I say “limited experience” because I’ve stayed at my last few jobs between 5 and 17 years each. So I’ve not really been switching that often and therefore usually not actively seeking new positions.
