- Most hackathons run 24 to 48 hours; online events may run for weeks with checkpoints.
- The word hackathon, hack plus marathon, appeared in 1999 at OpenBSD and Sun Microsystems events.
- List hackathons as projects or achievements, not formal work experience.
- Judges should give specific, actionable written feedback and concise post-event reports.
Setting up a hackathon means defining a purpose and audience, securing a venue or platform, sponsors, mentors and judges, publishing themes and rules, and running a well-paced schedule from kickoff to demos. I have competed in 10+ hackathons and founded the TechVerse Enclave community, so this page covers setting one up, ideal length, what hackathons include, where the name came from, whether hackathons count as experience, giving demos and SIH presentations, prize money, and how judges should give feedback and report.
How do you set up a hackathon?
Define the goal and audience, pick dates and format, secure a venue or online platform, recruit sponsors, mentors and judges, publish themes, rules and judging criteria, open registrations, and plan logistics such as food, Wi-Fi, power and schedules.
Also asked as: how to set up a hackathon
Work backwards from the event: two to three months before, confirm sponsors and the venue; six weeks before, open registration and announce tracks; two weeks before, brief mentors and judges and run team formation sessions; on the day, keep strict timings for kickoff, mentor rounds, submission and demos. Use Devfolio, Devpost or Unstop for applications and submissions, and a Discord server for communication. Afterwards, publish results quickly and send feedback forms.
How long should a hackathon last?
Most hackathons last 24 to 48 hours, often across a weekend. Shorter formats of 8 to 12 hours suit beginners and corporate events, while online hackathons may run for one to several weeks with flexible schedules.
Twenty-four hours is enough for a focused prototype; 36 to 48 hours allows more polish and rest. Longer online events let participants balance work or classes, but momentum can fade, so add checkpoints such as midpoint demos. Consider your audience: first-year students may prefer a single long day without overnight stays, while experienced developers enjoy weekend sprints. Whatever the length, protect time for judging, so demos are not rushed at the end.
What does a hackathon include?
A typical hackathon includes an opening ceremony, a theme or problem statement announcement, team formation, building time with mentor support, workshops or talks, meals and breaks, a submission deadline, demo presentations, judging and a closing ceremony with prizes.
Also asked as: what does hackathon include
Many also include sponsor challenges with separate prizes, networking sessions with recruiters, fun activities such as quizzes or games during long nights, and swag. Online hackathons replace physical elements with live streams, Discord channels, scheduled office hours and recorded demo videos. Participants usually need to submit a code repository, a short description and a demo video or presentation. Good events also include a code of conduct and clear support channels for help.
Where did the name hackathon come from?
Hackathon combines hack, in the sense of creative programming, and marathon. The term appeared in 1999, used independently by OpenBSD developers for a cryptography coding event and by Sun Microsystems for a programming challenge at its JavaOne conference.
Hack originally meant a clever solution or playful technical exploration, especially in early computing cultures at universities, before it took on its security meaning. Hackathons spread through the 2000s via tech companies and startup culture, with internal company hackathons producing well-known features. By the 2010s, student hackathons, government innovation challenges and corporate events had made the format global, including large national programmes in India such as Smart India Hackathon.
Does a hackathon count as experience?
Usually not as formal work experience, since it is not employment. List hackathons under Projects, Achievements or Extracurricular activities, unless the hackathon led to an internship or contract, which then counts as experience.
Also asked as: does hackathon come under experience
Hackathons still demonstrate experience in a broader sense: building under deadlines, teamwork, product thinking and presenting to judges. In interviews, treat them as project experience and describe your role, technical decisions and results. For freshers without internships, strong hackathon projects can fill much of the experience gap. Be accurate in applications: do not label a hackathon as a job, since background checks and interviewers may question it. Wins and finalist places deserve a clear line of their own.
How do you give a hackathon demo?
Show the product working on its core flow within the first minute, narrate what the user sees and why it matters, and keep the demo short and rehearsed. Prepare a backup video in case the live demo fails.

Before the demo, reset the app to a clean state, pre-fill test data, close unrelated tabs and notifications, increase font sizes, and test the projector and internet. Use realistic data, such as an actual user scenario, rather than placeholder text. Explain only the essential technology, then return to impact. End by stating what you built during the event and what is next. Have a teammate ready to answer technical questions while the presenter continues.
How do you give a Smart India Hackathon presentation?
Use the official SIH presentation template when provided, and cover the problem statement, your proposed solution, technical approach, feasibility, impact and benefits, research and references, and a demo or prototype screenshots, in a clear, concise flow.

Evaluators look for a precise understanding of the problem owner's needs, a workable technical plan and realistic deployment. Use diagrams for architecture and workflows, avoid dense text, and cite data sources. Highlight what makes your approach better than existing solutions. Prepare for questions on scalability, cost, security and integration with government systems. Rehearse as a team so every member can explain their part, and keep the presentation within the allotted time.
Does a hackathon give money?
Many hackathons award cash prizes to winners, and some offer sponsor prizes, travel support or stipends. Others give non-cash rewards such as gadgets, cloud credits, internships, incubation support or certificates.
Also asked as: does hackathon give money
Prize structures vary widely: student events may offer modest rewards, while large sponsored, government or Web3 hackathons can offer substantial prize pools across tracks. Read the prize rules for eligibility, payment timelines and tax requirements, since organisers may deduct tax at source and request identity documents. Participation itself is usually free. Treat money as a bonus: most of a hackathon's value comes from skills, projects, mentorship and connections that continue after the event.
How should hackathon judges give feedback that students use?
Make feedback specific, actionable and balanced: name one thing that worked, one or two improvements with a concrete next step, and a resource or example. Students act on precise advice far more than on general praise or criticism.
Also asked as: how hackathon judges should give feedback (so students actually use it
Good judges ask questions before critiquing, connect feedback to the judging criteria, and separate product, technical and presentation notes. Written feedback, even three bullet points per team, is more useful than a quick verbal comment students forget. Encourage teams that did not win by pointing to what would make the project competitive next time. Organisers can help by providing a feedback form for judges and sharing compiled notes with every team after results.
What should a hackathon judge include in a post-event report?
Include scores and rationale for top projects, observations on overall project quality, notes on whether judging criteria and time slots worked, any fairness or eligibility concerns, and suggestions for problem statements, mentoring and logistics next time.
Also asked as: what a hackathon judge should include in a post-event report to organisers
Organisers use these reports to improve future events and to give teams useful feedback, so be specific: which tracks produced strong work, where teams struggled, whether problem statements were clear, and whether demo time was sufficient. Flag issues such as pre-built projects or rule violations with evidence. Recommend promising teams for follow-up support, such as incubation or mentorship. Keep the report concise, ideally a page or two, and submit it soon after the event.
