What Interns Are Saying

"The work was genuinely challenging, and people were willing to explain the ‘why’ behind what we were doing. It changed how I think about a career in computing."

Undergraduate, SJSU, Computer Science and Data Science

"Mentors treated my ideas seriously from day one, and I constantly learned beyond my project. The Lab’s mission gave the work a sense of purpose that’s hard to find elsewhere."

Graduate, UC Berkeley, Electrical Engineering and Computer Science

"Social activities and events gave me additional opportunities to connect with people. The relationships I built felt real. I walked away more satisfied with this internship than I ever expected."

Undergraduate, UC Davis, Computer Science and Engineering
