I am planning to apply for a few undergraduate research internships and I recently learned LaTeX, so I am thinking of transferring my resume from Word to LaTeX. I came across LaTeX templates for a "Deedy CV" and a "Deedy Cover Letter" which apparently went viral in 2014. Admittedly, the "Deedy" templates look very attractive; in fact, they were the most attractive-looking CV/cover letter templates in the entire Overleaf gallery. Is it recommended that an undergraduate applying for undergraduate research internships uses the Deedy templates? What about a template for a somewhat infographic colored CV? Do these formats of CVs convey unprofessionalism in academia?
P.S. If this is relevant, I am in the US and am also planning to cold email some professors on the US to ask if they would be willing to take me on for a research position.
