System Design → Design a payment system that prevents duplicate transactions. → How would you scale an application from 10K to 10M users? → When would you choose microservices over a monolith? Databases → Why is your SQL query slow, and how would you optimize it? → How do you maintain data consistency across services? Distributed Systems → What happens if a server crashes during a database transaction? → How would you handle duplicate messages from a queue? Production & DevOps → Your production API suddenly becomes slow. How do you investigate? → How would you deploy a breaking change without downtime? Technical Leadership → Tell me about a major production incident you handled. → Describe a technical decision you made and the trade-offs involved. → How do you handle disagreements during code reviews? The biggest difference? A junior developer often focuses on implementing a feature. A senior developer also thinks about what happens when that feature fails, scales, becomes expensive, or needs to be maintained by another team. You don't need to master every tool on this list. You need strong fundamentals, depth in your domain, and the judgment to make reliable technical decisions. Years of experience may get you shortlisted. Engineering judgment is what makes you senior. Save this for your next career move.

everyone says AI is killing tech jobs. he got laid off and landed 7 offers in 60 days 👀

3,000+ LinkedIn requests and 1,000 emails for an internship opening in just 24 hours. The fresher job market is getting brutal. Is the real problem a lack of jobs, too many applicants, or hiring processes that filter out good candidates?

How many of you learned C from Harry? 🥹 From the golden era to the AI era. Anyone here from the 2026?

Dumb question: Can we run our React frontend and Node.js backend using the same Docker image? Or is using Docker Compose with separate images the better approach?

Genuine question: How does NetMirror make money? If users aren't paying for subscriptions, who's paying for the infrastructure?
