Heart of NTB
Bite-sized clarity for big interviews. Learn the way real engineers talkβno fluff, no gatekeeping, just guided momentum.
Complex concepts broken into everyday analogies so you can retell them during interviews without memorizing scripts.
Clean snippets with notes on performance, trade-offs, and how to extend themβperfect for live coding or whiteboard moments.
Curated prompts inspired by FAANG and startup loops, grouped by intent (conceptual, scenario, code) for targeted practice.
Trust me, I've felt that knot in the stomach minutes before a panel. These walkthroughs were written to calm nerves and build real confidence.
Remember: Good news: you're not alone. We'll untangle each topic together.
Too many tabs, conflicting advice, zero context? Same. NTB distills the essentials into a single guided path.
Remember: Solution: one hub for code, context, and next steps.
Those late-night 'do I even know this?' spirals birthed this project. Each section is the explanation I wish I had when I was stuck at 2 AM.
Remember: Read it, breathe, try again. The story sticks because it's real.
Nick Tech Bytes is built with input from peers who share wins, rejections, and aha moments.
Remember: We learn together, celebrate together, and ship together.
