The Israel Tech Challenge, three years in the making, is taking place this week, with 25 of the best Jewish college students in the world (chosen from some 500 applicants) in Israel for an intense insider look at how the Start-Up Nation does its magic. The Challenge — a cooperative effort between The Jewish Agency, the Government of Israel, and private investors — is designed to connect top students from the diaspora with tools and networks to enrich their careers in the hi-tech industry, and to develop connections with the Israeli high-tech industry.
