As someone who gets a ton of resumes from academia, I see these very often. The problem here is that they all look the same because everyone is using the 'moderncv' package. If you want to stand out, invest some time to create your own template (but otherwise, it's perfectly fine, at least you'll have the basic structure correct).
Well, I am not using "moderncv" at all. I use three packages: "geometry", "inputenc", and "graphicx". That said, it does not look as appealing as these "creative" resumes (made using HTML & CSS or Adobe Illustrator, etc)
