牛面
An AI-powered interview preparation platform for internet tech professionals, providing mock interviews, resume-driven question prediction, and a large question bank.
Tool overview
Niu Mian (牛面) is an AI interview preparation tool built specifically for internet technology roles. It features mock interviews with an AI interviewer that simulates real interview pressure and follow-up questioning; resume-based prediction that automatically generates 20 high-frequency questions with suggested answers and potential follow-ups; and a question bank covering Java, Go, front-end, AI/LLM, and more (4,000+ questions). These help job seekers translate knowledge into spoken responses and reduce interview anxiety.
The platform excels at replicating real interview intensity, including a “difficult” mode that once led to a 100-minute, 31-question session. Resume-tailored questions make preparation feel like an “open-book exam.” The WeChat Mini Program adds a gamified quiz mode for on-the-go practice.
However, stability is a known weakness. To control costs, the team initially provisioned minimal server resources, causing a crash within 5 minutes of launch due to traffic surges. The service is still unprofitable, and free features may be scaled back or monetized in the future.
