2025-07-10 · 11 min
LinkedIn Executive Summary
InterviewAI is live — a voice-interactive mock interviewer that reads your CV, tailors technical questions, and evaluates answers in real time. Built in 48 hours. This isn't prep. It's performance engineering.
Technical Deep-Dive
MVP Architecture Under Pressure
InterviewAI chains four ideas: understand the candidate's background, tailor questions to role and skill level, conduct a voice conversation, and score against clear dimensions. No fixed script — each session adapts.
We shipped in 48 hours by scoping ruthlessly: one interview format, one voice flow, one scoring framework. Band9AI later inherited the evaluation discipline from this build.
Session Flow (Conceptual)
{
"interview_flow": {
"inputs": ["resume", "target_role"],
"phases": ["warmup", "technical_depth", "problem_solving", "behavioral"],
"scored_dimensions": ["reasoning", "communication", "relevance"],
"output": "structured_scorecard_with_action_items"
}
}
Lessons for Band9AI Speaking
Pressure-faithful simulation requires fast feedback and visible scoring dimensions — the same principles behind IELTS speaking mocks. InterviewAI proved the loop; Band9AI scaled the evaluation mindset.
