Interview Copilot Features: What to Look For

Not All Features Are Created Equal
Every interview copilot markets a long feature list. But which features actually impact your interview performance? After testing every major tool, here's what matters and what's just filler.
Features That Actually Matter
1. Real-Time Transcription Speed
The copilot needs to hear the question, transcribe it, and generate a response before the silence becomes awkward. Anything over 3 seconds creates noticeable delays.
- Aissence: 116ms — essentially instant
- Final Round AI: ~500ms — acceptable but slower
- LockedIn AI: ~300ms — decent
Speed matters most for rapid-fire technical questions where pauses are more noticeable.
2. Screen-Share Exclusion
If the tool can be detected, it's a liability. This is the single most important feature for live interview use.
- Desktop overlay (Aissence): excluded from screen sharing, proctoring, and screen recording
- Browser extensions (Final Round AI, LockedIn AI): Detectable by IT monitoring and proctoring tools
Read the responsible-use policy before using any assistant in a live interview.
3. AI Model Selection
Different AI models have different strengths. GPT-4 is great for general knowledge, Claude excels at nuanced reasoning, Gemini handles multimodal inputs. Having multiple options means better answers.
- Aissence: 5 models (GPT-4o, Claude, Gemini, DeepSeek, Grok)
- Final Round AI: 1 model (GPT-4)
- LockedIn AI: 1 model
4. Mock Interview Practice
The copilot should help you prepare, not just assist live. Mock interview simulators build the foundation that makes live assistance effective.
5. Coding-Specific Support
For tech roles, generic Q&A isn't enough. The copilot needs to understand algorithms, data structures, and technical interview formats.
Features That Are Nice But Not Critical
- Multi-language support — Important only if you interview in non-English languages
- Analytics dashboard — Good for tracking practice sessions, not essential for performance
- Custom prompts — Power-user feature that most people never configure
- Interview recording — Useful for review but raises privacy concerns
Features That Are Pure Marketing
- "AI-powered" without specifics — Every tool is AI-powered. The question is which model, at what speed
- Unlimited questions — You'll never hit a limit in a real interview. Usage caps only matter during heavy practice
- 99.9% accuracy — AI accuracy is contextual. These numbers are meaningless without specifying what was measured
The Feature That Matters Most
Follow the interview or assessment rules
Use AI tools for preparation unless the employer explicitly permits assistance during the session. Do not use software to conceal prohibited help or bypass integrity controls. Review the Aissence responsible-use policy when the rules are unclear.
