AI Tech Interview Prep Coach
For Non-Native Professionals
Free · In‑App Purchases
**You can code. You can design systems. But when you have to explain it in English — you freeze, ramble, or sound unconfident. That's what FluentLab fixes.**
FluentLab is a real-time AI voice coach for non-native engineers preparing for tech interviews. Have a live voice conversation with an AI that asks real interview questions, listens to how you speak, and coaches your English — so you show up sounding like the senior engineer you actually are.
**PRACTICE REAL SCENARIOS:**
Behavioral, System Design, Project Walkthrough, Standup, Stakeholder Comms, Culture Fit, Salary Negotiation, a full Mock Interview, and free conversation.
**AFTER EVERY SESSION:**
• Interview verdict — Would Pass, On the Bubble, or Needs Work
• Score across grammar, vocabulary, fluency, and coherence
• What you nailed — the strengths already working for you
• Your biggest opportunity — the one fix that moves your score most
• Correction cheat sheet — the exact phrases you got wrong and how to say them better
**BUILT FOR:**
Non-native engineers, PMs, and data professionals who are technically strong but communication-nervous — preparing for FAANG, scale-up, or startup interviews, or just wanting to sound more senior at work.
**PRIVACY:**
Your voice is processed in real-time and never stored. Results are saved on your device only.
