Mock round

Practice with AI guidance or self-scored rounds

Use the AI mode when you want one-question-at-a-time coaching based on your local resources, or use the deterministic self-scored round when you want offline practice with no external model.

AI-guided mock interviewer

Practice one question at a time with feedback in two layers

AI provider configured

This mode uses your local question bank, offline packs, and saved resume profile to run an interview round. After every answer, it gives a plain-English rewrite first and an interview-ready rewrite second.

Voice practice

Your browser can read the interviewer aloud and fill the answer box from your microphone. That lets you practice speaking first, not only typing.
