An AI company doing leetcode-style interviews. Let that sink in
Andrew Jefferson@EastlondonDev
I interviewed at xAI, 3 of my 4 interviews were leet coding no AI allowed. No check whatsoever of my ability to use AI as an engineer. Compare with Replit where I’ve just been contracting - they’re creating new kinds of interviews where candidates get access to Claude code and the internal AI sandbox.

Does anyone actually still do competitive programming?
The best developers today orchestrate AI agents. They don't have to write algorithms from scratch in 45 minutes.
AI can beat every coder on LeetCode anyway.
It's wild how fast that stopped mattering.
Understanding how code works is still important, but writing it from scratch is not.

This isn't just a job posting — it's a movement. The future belongs to thinkers who write, not writers who think. Are you ready to craft words that actually mean something? Drop your Substack below. 🚀

In a world where anyone can generate 1,000 words in 10 seconds — the ability to craft words that actually mean something is not just a skill. It's a superpower. Let me be satisfyingly clear. We're not looking for writers. We're looking for thinkers who write. Here's the truth most people won't tell you: Content is abundant. Taste is scarce. We need someone who understands AI, lives in tech, and has a point of view that can't be replicated by a model. Part-time. Flexible. Remote. No resume. No cover letter. No "passion for synergy." Just drop your Substack, blog, or wherever you write. That's it. That's the application. Because the best writers don't need to explain why they're good — their work does it for them. And yes — this post was intentionally written like AI. If that bothered you, you might be exactly who we're looking for.

Tech interviews started with pen and paper. Then came phone screens, test centers, and online assessments.
The core challenge stayed the same: how do you actually find good people?
This is the era of AI in interviews.

Claude down? Fixed! Bugs: 1. No check if JSON is dict (TypeError on non-objects). 2. Incomplete type hint. 3. Config mutated caller's dict.
Fixes:
parse_payload now:
try:
data = json.loads(raw_data)
if not isinstance(data, dict):
self.logger.error('Payload not JSON object.')
return None
if 'token' in data: del data['token']
return data
except json.JSONDecodeError as e: ...
-> Optional[Dict[str, Any]]
__init__: self.config = dict(config) if config is not None else {}
Done, still prints 42. 🚀

Last weekend, Hari, our co-founder and CTO, went back to his alma mater NIT Trichy.
He joined the alumni panel at Pragyan and talked about college life, how HackerRank started, and lessons from the journey.
Good conversations with the next generation of builders.
Until next time, NIT Trichy.
