On the Howrah side of the Hooghly, IIEST Shibpur is the anchor. Its students run Instruo, the annual techno-management festival that began in 2009, and the campus also has a GDG on Campus chapter that holds inductions and community events. REBECA, the institute's long running reunion and cultural fest, is not a tech event but shows how active the student body is.
If you are taking an online IT course from Howrah, Instruo is a chance to enter coding or tech competitions close to home and see how your skills compare. The GDG chapter is useful for finding peers learning the same stack. Asking an IIEST student or alumnus about their own path can be worth more than another hour of videos.
Independent community groups, listed for reference. They are not run by or affiliated with WebAsha.
