My suggests are to follow the guidelines presented in Skype Icon in the CV template? in order to obtain a viable S-Logo symbol. Then include the LinkedIn and Skype symbols as part of the \extrainfo
content where you have more control over the placement of things:
\newsavebox{\skypeicon}
\savebox{\skypeicon}{\includegraphics[height=.8\baselineskip]{example-image}}% https://tex.stackexchange.com/q/172191/5764
\newcommand{\skypesocialsymbol}{\usebox{\skypeicon}}
\extrainfo{\linkedinsocialsymbol~XXXX \quad \skypesocialsymbol~XXXX \\
Born in XXX (XXX), on June XX, XXX \\ Car owner, License Drive A, B} %
In the above code snippet, there is no usage of \social
and \skypeicon
relies on getting an image from the linked post.
Here is an example using a tikz
approach:
\documentclass[10pt,a4paper,sans]{moderncv}
\moderncvstyle{classic}
\moderncvcolor{blue}
\usepackage{lipsum}
\usepackage[a4paper, top=1.5cm, bottom=0.5cm, left=1cm, right=1cm,nofoot]{geometry}
\setlength{\hintscolumnwidth}{3cm}
\renewcommand*{\namefont}{\fontsize{35}{80}\mdseries\upshape}
\renewcommand*{\titlefont}{\fontsize{15}{80}\mdseries\upshape}
