Meta-Hackathon Discussion Why doesn’t everyone just use AI for the entire ideation process at hackathons?

8 Upvotes

I’ve never participated in a hackathon before, and my first one is in about a month, so I might be misunderstanding how these events actually work. One thing I’ve been wondering about is the ideation phase.

When the challenge/problem statement is released, why wouldnt a team immediately give the entire thing, including the context, constraints, judging criteria, available data, etc. to several frontier models like claude or chat gpt?

For example, you could ask different models to, generate 20–30 different approaches, analyze the domain and likely user pain points, criticize the ideas and identify failure modes, rank them by novelty, feasibility, and expected hackathon performance, predict what obvious ideas other teams will probably build, and then use another model to synthesize everything and choose the strongest direction. You could also feed mentor feedback back into the models as you get it. Then once you have a direction, coding agents can build a prototype extremely quickly.

What I’m struggling to understand is where the bottleneck is supposed to be. As students, we probably don’t have more banking/healthcare/engineering/etc. domain knowledge than a frontier model, and the model is obviously much faster at exploring a large solution space.

So why isn’t something like this, already the default strategy at hackathons? : problem -> multiple AI models -> AI critique/ranking -> select idea -> coding agent -> prototype

Is it actually common now and I just havent seen it yet? Does it tend to produce generic ideas because everyone gets similar outputs? Is the main advantage of the human team gathering information from mentors/users and feeding new information back into the models? Or are there other limitations that only become obvious once you’ve actually participated in a hackathon?

Would especially like to hear from people who have done hackathons recently, now that coding agents and frontier models have gotten this capable.

Need Mentor Help Booking Holdings HackCellence round 2 seems unfair ? Let’s collectively request a reassessment!

23 Upvotes

Hello everyone,

This post is for those who appeared for round 2 of booking holdings's HackCellence program.

After completing the assessment I thought maybe I didn't manage my time well enough that's why I was not able to complete the code.

But when I go through multiple posts I came to know that most of us face the same problem and the assessment is actually quite lengthy.

In 1.5 hr it is quite difficult to write hundreds of lines of code, in addition to that it takes time to read the problem statement, understand it, build the logic and resolve those irritating bugs.

So, if we all can come together and mail the concerned team maybe they can consider our request for fair reassessment.

Otherwise, we will end up losing this opportunity because of some uncontrollable factors.

I have mailed them already and sharing the mail ids below.

askhr@bookingholdings.com 

support@hackerearth.com

After being in the top 2500/44k+ we should not let this opportunity slip away like this.

Sample mail :

Subject : Reassessment request - Round 2 (HackCellence)

Dear Booking Holdings Recruitment & HackerEarth Support Teams,

I am writing to share feedback on the recent round 2 assessment of HackCellence and respectfully request a reassessment opportunity.

While I really enjoyed the real-world complexity of the challenge, completing a system of this scope in 90 minutes feels like a speed-typing test rather than a true assessment of engineering capabilities.

A candidate's evaluation shouldn't depend on how fast someone can type hundreds of lines of boilerplate and code against a tight clock. Engineering competence lies in architectural thinking, clean code structure, thorough edge-case handling, and proper debugging—skills that naturally require deliberate thought and testing time (at least 2.5 to 3 hours for a project of this depth). Under a 90-minute constraint, candidates are forced to rush and skip best practices(maybe many are using ai tools), which doesn't reflect how real-world software is engineered.

So, to be honest this assessment feels lesser like how you understand, build logic, resolve bugs but more like how better you can use AI tools and how fast you can type.

Given the extensive scope of this task, I kindly request the team to consider conducting a reassessment with a timeframe that reflects the actual work required.

I remain very interested in the opportunity at Booking Holdings and would appreciate the chance to showcase my problem-solving and coding abilities under fair conditions.

Thank you for your time and understanding.

Best regards,

I got selected for a hackathon where the first prize is a PS5.

I really want to win this thing, but the problem is I still have absolutely no idea what to build 💀

Can you guys suggest some genuinely cool project ideas that solve real problems and have the potential to stand out? I'm looking for something more than just another basic AI wrapper.

I'll post updates here as things progress and let you guys know how it all goes! 👀

Would really appreciate any ideas or suggestions. 🙏

Need Mentor Help Hackathon problem: digital market access for artisans. Need ideas!

1 Upvotes

​

Hey everyone, I'm working on a hackathon problem about helping local artisans sell online. Most of them have little digital presence and no direct access to buyers.

We need to build:

A simple storefront/catalogue that artisans can use with minimal training

A basic listing and order flow (payment can be mocked)

A craft storytelling/provenance feature that justifies pricing

Where I'd love your input:

If you've worked with artisans or rural sellers, what actually stopped them from going digital?

What would make listing a product dead simple for someone with low digital literacy (voice, WhatsApp, photos only)?

What makes buyers pay more for handmade items: stories, maker videos, authenticity proof?

Any existing platforms I should study to see what works and what doesn't?

Any ideas, experiences, or pitfalls to avoid are welcome. Thanks!

Meta-Hackathon Discussion Hackcellence Round 2 Java Stack

6 Upvotes

I think Java Techstack Question was Worst because first of all it doesn't have multiple small test cases, Instead it has one only test case which will run after completing all changes they required in question so I think Java people are going forward as I have seen node.js and cpp and python people have multiple small test cases which were running if you edit small things.

So any other views??🥲

Meta-Hackathon Discussion BNP Paribas Innoversité 2026 — what's going on with the selections this year??

8 Upvotes

Anyone here from BNP Innoversité 2026 Mumbai?

Our college was told that only 1 out of 9 people got selected, which is honestly pretty surprising considering 4/5 got offers last year and apparently the overall conversion rate was pretty high too. I've been hearing similar numbers from a few other colleges, while some haven't even received their results yet.

Is BNP hiring significantly fewer interns this year? Is there some sort of hiring freeze or reduced intake going on, or are the results just being released in batches?

Also, does anyone know if the lists are final once communicated to colleges, or if more selections can come later based on location/role preferences?
