I'm a junior at UC Berkeley. I just recently transferred in and I'm now looking into getting internships but I've been having a hard time with it. Essentially, I have very little/no relevant experience that one might need to acquire an internship. Throughout high school and my years at community college I was a full-time caretaker for my mom and generally had a lot of personal problems. It's not an excuse for not being more involved but just an explanation for why I wasn't - I don't know if I personally could have handled the additional stress. All I have in terms of experience is 3 volunteer positions I held (very minor ones, and one was in high school).
My question is, does anyone have any advice on how I could get my foot in the door professionally? I'm not talking about a paid internship - I just want to acquire some experience and pick up skills. I'm a dedicated student and I would be a dedicated worker, if I could get a chance! I'm really, really interested in getting involved, but every position I've applied for hasn't replied back because (I'm assuming) of my less-than-stellar resume.
I'd really appreciate any help - resources you used to get internships, general advice, etc. Thanks!
