Backend Interview: 10,000 users. Each email takes 100ms. Total time: 1000 seconds. 16 minutes to send all emails. One change makes it 10x faster. Same result. Same emails. What's the fix? 🤔

Every developer has this moment: You spend 3 days debugging. Reading logs. Adding console.logs. Rewriting the whole function. Finally ask a colleague. Explain the problem out loud. Halfway through explaining - you find the bug yourself. They said nothing. You solved it. This is called Rubber Duck Debugging. And it works every single time. What's your most embarrassing rubber duck moment? 👇

You build a ticket booking app. Concert has 1000 seats. Tickets go on sale at 10 AM. 10:00:00 AM - 50,000 users click "Book Now" 10:00:01 AM - 1000 seats available 10:00:02 AM - 2,847 bookings confirmed 1,847 people paid for seats that don't exist. No overselling was supposed to happen. It did anyway. How do you design this to be bulletproof? 🤔

Agentic Ai interview question: Your agent adds an item priced at ₹10,000 to the cart. At checkout, the price changes to ₹12,000. Should the agent continue? How would you prevent an unexpected purchase?

The agent should stop and ask for confirmation. A good agent should never silently accept a price change. The checkout flow should re-validate the price and require explicit user approval if it changed.

Revenue doesn’t excuse a terrible first impression. The opening experience is part of the product.

Why are people still using Overleaf when OpenAI Prism exists? If you’re writing research papers, working with LaTeX, or collaborating on academic docs, Prism feels like a massive upgrade. Overleaf was the standard. But standards change.

Because switching tools has a cost too. But if Prism makes the workflow significantly faster, Overleaf’s default advantage won’t last forever.

Which one would hurt developers more if it disappeared tomorrow? - GitHub - Stack Overflow - VS Code - npm - Docker

Absolutely. Building is getting cheaper; getting attention, trust, and customers is becoming the real moat.

If AI makes building a startup 10x faster, will distribution become the biggest bottleneck?

Day 3. Who’s building? 👀 I’m on the road from 2.2K → 5K+. Drop what you’re building below. I’ll check out your profile and connect with interesting builders. Let’s grow together🫶

who's actually getting fired first the developer who relies heavily on AI or the developer who refuses to use it be honest

The one who refuses to adapt. AI reliance can be fixed; resistance to change is harder.

Being a software engineer in 2026: - Keep learning or fall behind - Ship faster than ever - Watch AI change your role - Worry about layoffs - Take on more responsibility - Try to have a life outside work And after all that: “We’re restructuring”

You can do everything right and still get caught in a spreadsheet decision. That’s the brutal part.

4 database queries. Running one by one. Total time: 800ms. Each query takes 200ms. None depend on each other. One change makes it 200ms. Same result. What's the fix? 🤔

Agentic AI interview question: Your agent generates a query that works with 1,000 rows but scans 100 million rows in production. How would you protect the database from an expensive agent-generated query?
