rvivek··on 2025 HackerRank Developer Skills Report
We just published our 2025 Developer Skills Report. It combines survey responses from over 13,000 developers worldwide with platform data from millions of coding assessments on HackerRank.

Would love to hear your thoughts and responses.

rvivek··on Ask HN: What can HackerRank do better?
That's awesome. I'm sorry, I couldn't find your email / contact info from your profile. Any chance you can email me: vivek [at] hackerrank?
rvivek··on Ask HN: What can HackerRank do better?
Before you replace, can I show you how the LLM integration works on HackerRank?
rvivek··on Ask HN: What can HackerRank do better?
What would a solution like that look?
rvivek··on Ask HN: What can HackerRank do better?
We already have this but perhaps we should make it more prominent
rvivek··on Ask HN: What can HackerRank do better?
Thank you for logging back in! I’d say the biggest differentiator among the ones you have mentioned is our connect to 3000+ companies who use our enterprise platform to screen & interview candidates. They would also like to interview interested candidates from the community.

On the pure play practice, we are working on introducing more real-world challenge set up + a real AI tutor

rvivek··on Ask HN: What can HackerRank do better?
Thanks for the transparency. We will continue to get better at making it easy to get started

Super good feedback. It’s on top of our list to move to more real-world set up like how you are mentioning
rvivek··on Rippling raises $500M in emergency funds after SVB fails
There’s no universal agreed upon definition for a startup but if at all you want to think of one, use growth rate. They have 1000 employees and $1b in the bank now. They had 1000 employees and $500m 48 hours back. They had 500 employees and $250m a year ago. They had 250 employees and $100m 2 years ago and so on..

No “non-startup” can grow at that pace.

rvivek··on Rippling raises $500M in emergency funds after SVB fails
Wow, I'm surprised at the level of cynicism here. As a startup, the last thing on your mind is trying to optimize for a situation when a major bank collapses that too in a matter of days. There are many more urgent fires to put off. Sure, as a payroll company, you may wonder if this is indeed an edge case they need to take care of but the way the team, VCs harnessed in such a short period of time to delight customers is commendable. Think about all the things that needed to happen.

--> Move the primary banking provider from SVB to JPMC.

--> Get a set of engineers to have all-nighters to ensure the new payment system actually works. This is hundreds of millions of dollars worth of risk.

--> Raise $500m(?!!) in 48 hours to fund the payroll without any assurance from FDIC whether depositors are going to get the money back or not.

--> While doing all of this, respond to a massive influx of support tickets.

What this really shows is they are willing to go to a crazy extent (raise $500m in 48 hours!) to delight customers.

FWIW, I'm not affiliated with Rippling in any way but I do have a ton of respect for Parker for his ability to bounce back after the Zenefits debacle.

rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
I'm sorry. I should have clarified and I can't edit my original comment now. I meant plagiarized problem statements. Usually these sites have the entire problem statements from our website along with the solution (aka code snippets to solve.)
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Here's what we are doing: https://news.ycombinator.com/item?id=31092085 You are right. HN thread triggered this. And we are working on fixing this at the core.
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Yes, agree https://news.ycombinator.com/item?id=31092085
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
It is fucking happening.
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Yes, absolutely. Apologies for the disruption we caused. We are going to make a donation and here are the changes we are making https://news.ycombinator.com/item?id=31092085
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Hello again, Vivek, founder/CEO here. In the interest of moving swiftly, here are the actions we are going to take:

(1) We have withdrawn the DMCA notice for sympy; Sent a note to senior leadership in Github to act on this quickly.

(2) We have stopped the whole DMCA process for now and working on internal guidelines of what constitutes a real violation so that these kind of incidents don't happen. We are going to do this in-house

(3) We are going to donate $25k to the sympy project.

As a company we take a lot of pride in helping developers and it sucks to see this. I'm extremely sorry for what happened here.

rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Oscar, thank you for responding and I'm terribly sorry for the disruption this has caused. I should have taken this more seriously when it sprung up on HN the first time but for whatever reason we just fixed that problem and moved on. This is a serious one and we are working on a strategy that is sustainable.

Meanwhile, if we need to make a monetary contribution for your effort or anything more we could do to promote, what would be the best way to do it? If you'd like to send me an email to discuss further, I'm available at vivek at hackerrank

Thank you & sorry!

Good distillation. Will follow-up with a blog post on this.

I literally said this in the comment above -- "That said, ultimately, we are accountable for this because it's our reputation is at stake."
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Phew, this sounded like a scene from a Tarantino movie. We engage a 3rd party for this service. That said, ultimately, we are accountable for this because it's our reputation is at stake. We are looking into it ASAP and this action will be reverted. We do need to get to the RCA to ensure we are giving strict guidelines on DMCA activity with the 3rd party or perhaps even consider switching to a new one.
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Sorry to hear. I just sent you a note. Appreciate your response.
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
It's not an either or. We need to do the takedown AND figure out a way where we can do things like randomizing questions but preserving the integrity of it to ensure a fair evaluation, etc.
rvivek··on HackerRank (YC S11) DMCA'ed the SymPy Docs [fixed]
Hello, I'm Vivek, founder/CEO of HackerRank. Our intention with this initiative is to takedown plagiarized code snippets or solutions to company assessments. This was definitely an unintended consequence. We are looking into it ASAP and also going to do an RCA to ensure this doesn't happen again.

Sorry, everyone!

rvivek··on Optimizely to be acquired by Episerver
BTW, I'm not sure if you would have expected them to get to $100m in ARR either when you passed on them because you were skeptical of the market. There's a lot between $1m to $100m ARR that can go wrong. In this case, I don't think it was the market opportunity.
rvivek··on Ask HN: What makes a good technical leader – any recommended books?
The biggest change is to change your mindset to "it's your job to enable the team to do the work vs you doing it." So, whenever you are thinking about doing X, think about how to enable your team to do X. This is not trying to be lethargic but working to make yourself redundant, which is the highest success for a leader, IMO.
rvivek··on Excalidraw whiteboard – easily sketch diagrams with a hand-drawn feel
Love excalidraw! This might seem like a plug but someone asked for a collaborative embed. We actually integrated theirs in our pair programming solution for system design interviews: https://www.hackerrank.com/products/codepair
