Voice-First AI Technical Interviewer • Real-Time Code Visibility

Realistic Coding Interviews That Hear, Watch, & Coach You

Experience an authentic technical evaluation powered by conversational AI voice. The interviewer speaks out loud, observes your keystrokes live via WebSockets, provides gentle coaching hints when you get stuck, and outputs a rigorous hiring scorecard.

“Welcome! Let's start with a coding challenge in Python. How would you group anagrams from a list of strings in O(N × K) time?”

Candidate (Spoken Live)

“We can iterate through each word, sort its characters or build a character count tuple as a hash map key, and append the original word.”

“I see you started setting up the hash table. Remember that in Python, tuples are hashable and can be used directly as dictionary keys.”

How the AI Technical Interview Works

From voice greeting to sandbox execution and final hiring scorecard.

01

1. Stack & Difficulty Setup

Choose from 9 specialized language banks (JavaScript, Python, Java, C++, C, C#, SQL, HTML, CSS) and select your target seniority level (Junior, Mid, Senior).

2. Conversational Phone Call

The interviewer conducts dialogue naturally using Shunya Labs Voice AI. You speak into your microphone, with automatic silence detection for natural turn-taking.

3. Live Code & Proactive Hints

Monaco Editor streams your keystrokes over WebSockets. When you pause or struggle for >35s, the AI inspects your uncommitted buffer and speaks a targeted micro-hint.

4. Evaluation & Scorecard

Your code executes in an isolated sandbox. The FSM scores correctness, communication, and depth to generate a Hiring Decision Scorecard with radar charts and rubric audit logs.

Reliable Infrastructure Under the Hood

Engineered with multi-model fallback resiliency, isolated compilation, and automated audio synthesis.

OpenRouter Multi-Model Fallback Chain

Automatic silent failover across Claude 3.5 Sonnet, GPT-4o, Gemini 2.5 Pro, DeepSeek, and LLaMA 3.3. If an upstream model is rate-limited, the interview proceeds without interruption.

Zero rate-limit aborts
Emergency structured rubric synthesis

Shunya Labs Neural Voice AI

High-fidelity audio generation using Shunya Labs Zero-TTS with the Varun voice profile and zero-indic model for natural dialogue cadence.

Live speech turn-taking
Instant spoken coaching hints

Deterministic FSM & Sandboxing

Finite state transitions maintain interview structure without hallucinated phases. Sandboxed compiler executions measure runtime, stderr, and memory safely.
