Pertaining to getting a job after college with an engineering degree, how much do employers value retail/research experience?

I have two more years to go before completing my EE degree. I currently only have a three month research internship and two years of retail/customer service work experience under my belt. Should I continue to pursue these, or should I look for something else if I want to improve my chances of getting a job right out of college?

Thank you for the input!
