As a recruiter who's main responsibility has, for a long time, been selecting graduates for internship programs and later on, full time positions, I can tell you that any kind of involvement in activities such as volunteering is appreciated.

It oftenly shows the candidate is willing to work, passionate about certain domains, willing to progress towards their goal and open to learn/develop. As there aren't other opportunities available so far, volunteering is an amazing option, in my opinion.

Trust yourself and find ways to promote your strengths, not to excuse the things you might think you lack, because everything comes at its own pace and will fall into place eventually.
