Build the technical fluency to walk into your next interview prepared. InterHub turns interview prep into a structured, adaptive practice routine, built specifically for software engineers targeting junior, mid, and senior roles. Pick your career path - backend, frontend, fullstack, mobile, DevOps, or AI, choose the technologies you actually use, set a target seniority, and InterHub generates a learning plan that adapts to your answers. Every session you complete sharpens the next one. WHY ENGINEERS USE INTERHUB: Adaptive Question Sessions Questions are selected based on your career path, chosen stack, and how you've answered previously. The system tracks weak topics and reinforces them - no padding, no filler, no cramming a curriculum that doesn't match your goal. Realistic Mock Interviews Run full mock interviews end-to-end. Answer by typing or by speaking, voice answers are transcribed and scored just like a real interviewer would assess your reasoning. Each interview ends with an overall verdict, per-question scores, and structured feedback you can act on. Progress Tracking That Reflects Reality Track your level per technology and across the radar of skills your target role requires. Snapshots over time show whether you're actually closing the gap to the seniority you're aiming for, or only practicing what you already know. Practice Mode for Daily Reps Short, focused sessions for the days you have ten minutes between meetings. Local on-device speech recognition means you can practice out loud without anything leaving your phone unless you opt in to cloud transcription for higher accuracy.
