Girls who are currently in Grades 10-11 — and interested in technology and willing to learn — are invited to apply now for the 5th annual Summer Immersion Program offered by the non-profit Girls Who Code.  It’s a free, 7-week summer program hosted by various technology companies to provide project-based education in computer science, connections with female engineers, and exposure to tech careers.  It’s an introductory course, and no previous experience is required. This year, there will be 75 Summer Immersion Programs sponsored by 39 major companies and philanthropic foundations serving over 1,400 girls in 11 cities. Locally, programs will be hosted by Trip Advisor in Needham and Akamai and Twitter in Cambridge.
