Stanford Summer Business Program worth it?

I'm a junior at a LAC with a psychology major and with only two economics courses and one math course under my belt (will enroll in one or two financial statistics/marketing related courses next semester). My GPA is solid (3.7-3.8). I have no business experience and have mainly worked in academic research, but I would really like to get a job with a Silicon Valley tech company on the business/sales/user operations side of things. What type of experience should I be looking for next semester? Does anyone know of anyone who's gone through this program? I understand that many juniors get job offers from their summer internships prior to junior year so I want to make it count.
