As answered by people managing DevFinanceTools and MockInterviewAI.
MockInterviewAI's answer:
MockInterviewAI is a real-time voice AI interview platform - the interviewer actually talks back instead of just chatting via text. It combines voice conversation with a live code editor and interactive whiteboard, so you can practice coding and system design interviews the way they actually happen. It also supports 10 languages and provides detailed feedback reports after each session.
MockInterviewAI's answer:
Most interview prep tools are text-based chatbots or pre-recorded question banks. MockInterviewAI uses real-time voice with WebRTC for natural, low-latency conversations. You get a live code editor for coding interviews, an interactive whiteboard for system design, and post-interview feedback reports with scoring. It covers coding, system design, behavioral, and more interview types in one platform.
MockInterviewAI's answer:
Software developers and tech professionals preparing for job interviews. This includes junior developers practicing for their first technical interviews, experienced engineers preparing for FAANG-level system design rounds, and professionals in any field who want to sharpen their behavioral interview skills. The platform supports 10 languages, making it accessible globally.
MockInterviewAI's answer:
MockInterviewAI was built to solve a real problem - practicing for technical interviews is hard without a real person to talk to. Text-based tools don't replicate the pressure of a live conversation. So we built an AI interviewer that you can actually speak with, complete with tools like a code editor and whiteboard, to make practice feel like the real thing.
MockInterviewAI's answer:
The frontend is built with Next.js. Real-time voice uses WebRTC with a modular pipeline and Langgraph agentic workflow.
