AI interviews are an innovative solution that leverages artificial intelligence and high-quality real-time audio and video communication to enable automated online interviews. In traditional interview processes, limitations such as the number of interviewers, scheduling constraints, and subjective evaluations often lead to inefficiency, high costs, and poor experiences for enterprises during large-scale recruitment and talent screening. With AI real-time conversation capabilities, AI interviews provide enterprises and candidates with a standardized, efficient, and 24/7 online interview experience. AI interviewers, powered by large language models (LLMs), can engage in natural conversations with candidates, ask and follow up on questions in real time, assess candidates’ comprehensive abilities, and automatically record and organize textual data from interviews to support subsequent evaluations.
TRTC technology serves as the foundational support, delivering stable, high-quality, and low-latency audio and video communication for AI interview scenarios. Its cross-platform and global interoperability advantages allow interviewees to confidently use any device—including iOS, Android, Windows, Mac, Web, and WeChat/QQ mini programs—to participate in AI interviews anytime, anywhere. Whether for initial screening or in-depth Q&A, TRTC ensures clear and smooth communication, offering a user experience comparable to native applications.
For enterprise developers, TRTC provides a rich set of scenario-based UI components and low-barrier integration capabilities, enabling rapid integration and deployment with just a few lines of code. Whether deploying AI interview entry points in proprietary apps, public accounts, or mini programs, enterprises can easily implement their solutions.
Tencent RTC Implementation Solution
A comprehensive AI interview scenario typically includes the following key modules: real-time audio and video, TRTC Conversational AI , large language model (LLM), text-to-speech (TTS), and interview management backend.
Real-Time Communication: Powered by TRTC, offering high-quality, low-latency audio and video connections, supporting 720P/1080P/2K HD video and 48kHz high-fidelity audio. Regardless of network conditions, smooth interactions are ensured, simulating real interview scenarios.
Conversational AI: Tencent RTC’s Conversational AI solution allows customers to flexibly integrate various AI large model services, enabling real-time audio and video interaction between AI and users, and building AI real-time conversation capabilities tailored to business scenarios. Leveraging Tencent RTC’s global low-latency transmission, voice conversation latency can be as low as 1 second, delivering natural and realistic dialogue effects. Integration is convenient and ready to use out of the box.
Large Language Model (LLM): Intelligently understands candidates’ speech content and context, accurately extracts key points from responses, dynamically generates follow-up interview questions, and enables personalized and structured interview processes. LLM technology can also automatically adjust scoring criteria based on different job algorithms, improving the fairness and accuracy of assessments.
Text-to-Speech (TTS): Supports integration with third-party TTS services, offering output in multiple languages and voice styles. AI interviewers can use TTS technology to present different tones and personalities, closely simulating real interviewers and enhancing the candidate experience.
Instant Messaging (IM): Key business signaling is transmitted via the IM SDK.
Interview Management Backend: Includes question bank and interview design, automated scoring, data storage, visual analysis, interview scheduling, and more.
Before starting integration, you need to activate TRTC/LLM/TTS services and prepare the necessary resources. TRTC Conversational AI supports any LLM model that complies with the OpenAI standard protocol, as well as LLM application development platforms such as Tencent Cloud Intelligent Agent Development Platform, Dify, and Coze. For specific integration methods, please refer to our Quick Start Guide and use our provided demo code to quickly build your AI interview service.
Why Choose Tencent RTC
As an industry-leading RTC provider, TRTC offers users the most optimal and lowest-latency connection channels, integrating and deeply optimizing capabilities such as ASR, LLM, and TTS. This enables total AI conversation latency to be reduced to as low as 1000ms, comparable to human response speed. The solution also incorporates innovative features such as voiceprint recognition, semantic segmentation, background sound, and emotion recognition, making conversations more natural and realistic.
Additionally, the solution is equipped with multi-service disaster recovery capabilities and leverages Tencent Cloud’s global network of over 3,200 acceleration nodes, as well as proprietary technologies like intelligent encoding and dynamic access, to comprehensively enhance call smoothness and stability. The TRTC Conversational AI solution also supports the RAG framework, allowing the retrieval system to access the latest and most authoritative external knowledge. This ensures that responses are fact-based, effectively avoiding the “hallucination” issues common in traditional generative models, and significantly improving the accuracy, timeliness, and traceability of generated content.
