What creates the delay
- Audio capture: the assistant needs enough speech to identify a useful question.
- Speech recognition: audio is converted into text, often while the interviewer is still speaking.
- Network travel: the transcript and context travel to the service and the response returns.
- Model processing: the model reads the question, resume context, and instructions before producing text.
- Rendering: the desktop app displays streamed or completed output.
A long question can feel slower even when the system is fast because the assistant should not answer before the interviewer has supplied the key constraint.
Measure time to first useful text
Full-answer time is less important in a live interview than time to the first useful sentence or bullet. Streaming can expose the beginning of an answer while the rest is still being generated.
For a realistic test, run ten questions in a practice call. Start timing when each question ends and stop when the first usable response appears. Record the median and the slowest result, then repeat on your normal network with the same resume context and response style. This gives you a setup-specific measurement instead of a marketing number.
What makes an assistant slower
- Unstable Wi-Fi, VPN routing, or high network congestion.
- Long custom instructions, large resumes, and excessive conversation history.
- Verbose requested answers when short spoken bullets would work.
- Noisy audio, overlapping speakers, or the wrong input device.
- High CPU or memory pressure from the meeting app, browser, editor, and recording tools.
- Screenshot questions containing tiny, cropped, or irrelevant visual content.
How to reduce perceived latency
- Use a stable connection and close unnecessary high-bandwidth apps.
- Select the correct microphone or system-audio source before the call.
- Customize responses for concise bullets and natural spoken language.
- Use typed prompts for short follow-ups rather than waiting for speech recognition.
- Use screenshots when the important information is visual.
- Keep the overlay close enough to the speaker tile that the first streamed text is easy to notice.
Latency is only one quality metric
A fast irrelevant answer is worse than a slightly slower answer grounded in the actual question and your resume. Evaluate relevance, factual accuracy, readability, stability, and time to first useful text together. Always run a practice call before an important permitted interview.
