Last October we ran the biggest Hacktoberfest meetup Kolkata has had: 290+ people in one room, most of them making their first open-source contribution. This is the honest version of how it came together — what worked, what we'd cut, and the parts nobody warns you about.
Why a meetup, and not just a "come code" day
The default Hacktoberfest event is a hall full of people each grinding alone toward four PRs. We didn't want that. The goal we set was simpler and harder: every first-timer leaves with one real, merged-quality contribution and knows how to get the next one on their own.
That one decision shaped everything else — the format, who we invited to speak, how we laid out the room.

The format that actually worked
We split the day into three blocks:
- The "why" (30 min). Not a lecture on git. A short, honest talk on what open source actually is, why maintainers want contributors, and why "good first issue" is a real invitation and not a trap.
- Hands-on, in small pods. There were 6 speakers from different Google Developer Group Chapters! They delivered their own thoughts and works on Open Source Ecosystem!
- Open floor + debrief. People showed what they shipped. We talked through the PRs that got stuck and why.
The pods were the thing. I still remember Deep Saha a very close brother of mine, ig it was his first stage talk and he delivered his experiences during Hacktoberfest and how he became a super contributor.
Logistics: the unglamorous list
- Venue & capacity. JIS University had allowed me to use the university auditorium with an in house count of 290 participants in a single room for the event.
- Sponsors. The event was sponsored by ISTE and pollinations.ai with the core support of food / swags and a lot of logistics. We had delivered flowers pens certificate of talks and a lot more!
- Registration vs. show-up. We registered 350 candidates! and ~290 actually came.
- Mentors. We were glad to have GDGoC Samrat Talukdar, GDGoC Nazreen Imam, Saugata Sarkar, Ex-GDGoC and GCE Abhishek Kushwaha in house, with a lot of fun sessions and talks!
What we'd do differently
Honest part about this are some misunderstandings that had happened with the venue itself! It was regarding the lunch support for the candidates present there. Except for that it was a pleasing event for me and the candidates so far.
The outcome that mattered
Attendance isn't the only win. From the event we had cartered tons of connections / profiles and a lot of activities on the go. The immense crowd had shared a lot of fun stories and we swarmed our LinkedIn posts! -- Hacktoberfest Meetup LD Dump
To be very honest being a GDGoC myself, I was pleased to watch the community actively participating in such an event and it was a great great innitiative taken collectively.
If you're thinking about running one: start from the outcome you want a first-timer to walk away with, and build the day backward from there. Everything else is logistics.

Special thanks to , and for being there with us during the event.
