ExtraBrain Interview Questions
5 AI Interview Platforms Worth Trying for Smarter Interview Prep
Compare AI interview platforms for practice, feedback, live context, video interviews, peer mocks, and responsible candidate support.
AI interview platforms can help candidates practice more often, get clearer feedback, and stay calmer when interviews become unpredictable. The best tool depends on what you need most: live interview context, mock interview repetition, peer practice, video assessment practice, or structured lessons.
This guide compares five useful options for candidates: ExtraBrain, Cluely, Pramp, HireVue, and Big Interview. It focuses on how each platform fits into responsible interview preparation, not shortcuts that violate employer, school, workplace, or platform rules.
1. ExtraBrain: Best local-first desktop AI interview and meeting copilot for Mac
Overview
ExtraBrain is a free, local-first desktop AI interview assistant and meeting copilot for Mac. It is built for live transcription, screen-aware context, interview answer structuring, follow-up questions, technical explanations, and post-session review.
ExtraBrain works especially well when you want one desktop workspace for coding interviews, system design rounds, behavioral interviews, product interviews, meetings, lectures, and research calls. It is available for macOS today, including Apple Silicon and Intel Macs, with Windows and Linux planned.
What makes ExtraBrain different
ExtraBrain is not only a mock interview site. It is a live desktop copilot that can help you follow an interview as it happens, organize the transcript, interpret screen context, and prepare better follow-up answers.
Key strengths include:
- Live transcription for interview and meeting context.
- Screen-aware context for coding, system design, product, and case-style conversations.
- Local Parakeet transcription and local Gemma 4 on-device AI where installed and compatible.
- Bring-your-own AI provider setup, including Anthropic, OpenAI, custom OpenAI-compatible endpoints, Claude Subscription, and Codex Subscription.
- Clear privacy controls so users can understand when data stays local and when selected providers may receive prompts, transcript text, screenshots, audio, or context.
- Post-interview review for transcripts, notes, missed points, and follow-up preparation.
Mock interview and practice workflow
ExtraBrain can help you practice by turning your resume, role description, notes, and previous interview history into better answer outlines. For behavioral questions, it can help shape STAR answers without making them sound generic. For technical interviews, it can help explain tradeoffs, edge cases, debugging steps, and system design reasoning.
A practical practice session might look like this:
- Paste or summarize the role and expected interview format.
- Ask ExtraBrain to generate likely questions for the role.
- Practice aloud while transcription captures your answer.
- Review where your answer was vague, too long, or missing a concrete example.
- Rewrite the answer in your own words and practice again.
Live interview support
An AI interview copilot can be useful during live interviews when rules allow it. ExtraBrain can help candidates follow the conversation, structure answers, generate clarifying questions, and recover when they lose the thread.
The responsible way to use live support is to treat it as a thinking aid, not a replacement for your own skills. You remain responsible for accurate answers, honest representation, and compliance with interview, employer, school, workplace, and platform rules.
Privacy and local-first options
ExtraBrain is designed for candidates who care about privacy and control. A fully local posture requires local Parakeet transcription plus local Gemma 4 on-device AI where installed and compatible, with no external provider requests. If you choose external providers, selected prompts, transcript text, screenshots, audio, or context may leave the device depending on configuration.
This makes ExtraBrain a strong fit for users who want a practical balance between local-first workflows and provider flexibility.
Best for
ExtraBrain is best for Mac users who want real-time desktop interview support, local-first options, screen-aware context, and post-interview review in one workflow. It is especially useful for candidates preparing for coding interviews, system design interviews, behavioral interviews, product interviews, and high-stakes remote calls.
2. Cluely: Real-time context assistance for calls and focused work
Overview
Cluely is often discussed as a real-time AI assistant for calls, meetings, and focused work. For interview preparation, its main appeal is fast context support while a conversation is happening.
Candidates may find this useful when they want reminders, notes, or context during practice sessions and permitted interview settings. As with any live assistance tool, responsible use matters. You should only use it where AI assistance, transcription, screenshots, or notes are allowed.
Real-time context support
A real-time context assistant can help you remember earlier points in a conversation. It can surface notes, summarize what was just said, and help you stay organized when the interviewer changes direction.
For candidates, that can reduce panic in moments like:
- A recruiter asks you to connect your past work to a new role requirement.
- A hiring manager returns to a detail from the beginning of the call.
- A technical interviewer asks for a tradeoff you mentioned earlier.
- A panel interview jumps between behavioral, product, and technical topics.
Candidate use cases
Cluely-style assistance is most useful when your challenge is attention and recall. It can support prep, solo rehearsal, and meeting-style interviews where permitted.
Useful workflows include:
- Reviewing notes while practicing answers.
- Keeping company facts and role details close at hand.
- Tracking important points from a live conversation.
- Summarizing practice sessions so you know what to improve.
Best for
Cluely is best for candidates who want broad real-time context support across calls and meetings. If you need a Mac desktop interview copilot with local-first options, screen-aware interview context, and transcript review, ExtraBrain is the more interview-specific choice.
3. Pramp: Peer mock interviews for realistic practice
Overview
Pramp is useful because it connects candidates with other people who are also preparing for interviews. Instead of practicing alone, you can take turns as interviewer and interviewee. This makes practice feel more realistic and helps you understand both sides of the interview process.
Peer mock interviews
Peer interviews are valuable because they introduce unpredictability. You may get a follow-up question you did not expect, a different communication style, or feedback from someone who notices habits you miss.
This is especially helpful for:
- Coding interviews where you need to explain your thinking aloud.
- Behavioral interviews where your examples need clarity and structure.
- Product or case interviews where communication matters as much as the answer.
- Candidates who feel nervous speaking to a real person.
AI feedback and human feedback
Peer feedback is useful because it shows how another person experienced your answer. AI feedback can add another layer by identifying pacing, clarity, structure, and repeated filler words.
The best approach is to combine both. Use peer feedback to understand your communication impact. Use AI feedback to identify repeatable patterns you can improve before the next session.
Community support
Interview prep can feel lonely. A peer practice community gives candidates accountability, encouragement, and a way to learn from others who are facing similar interviews.
You may benefit from Pramp if you learn best by speaking with real people instead of only working through written prompts.
Best for
Pramp is best for candidates who want realistic peer practice and social accountability. It pairs well with ExtraBrain because you can practice with peers, then use a transcript-focused workflow to review what happened and improve your answers.
4. HireVue: AI-assisted video interview assessment practice
Overview
HireVue is best known as a video interview and assessment platform used by employers. Candidates often encounter it in remote hiring processes where they record answers or complete structured assessments.
For candidates, the most useful takeaway is not that HireVue is a prep coach. It is that video interview skills now matter, and practicing this format can help you communicate more clearly when the real assessment arrives.
Video interview practice
Video interviews feel different from live conversations. You may be speaking to a camera, managing a timer, and answering without normal social cues. That can make even strong candidates sound flat or rushed.
To prepare for video interviews, practice:
- Looking at the camera while staying natural.
- Giving concise answers with a beginning, middle, and end.
- Using concrete examples instead of broad claims.
- Keeping your voice steady under time pressure.
- Reviewing recordings to spot distracting habits.
AI skill assessment awareness
Some employer assessment tools use AI-assisted workflows to evaluate candidate responses or support recruiter review. Candidates should avoid trying to game these systems. A better strategy is to prepare clear, relevant, honest answers that show the skills the role requires.
If a platform provides practice feedback, use it to improve communication quality, not to create a false performance.
Best for
HireVue is most relevant for candidates preparing for asynchronous video interviews and structured employer assessments. ExtraBrain can complement that preparation by helping you draft concise examples, rehearse answers aloud, and review transcripts before recording.
5. Big Interview: Structured interview lessons and practice materials
Overview
Big Interview is designed as a broader interview preparation toolkit. It combines lessons, practice questions, recording workflows, and feedback to help candidates build confidence over time.
This makes it useful for students, early-career candidates, career switchers, and anyone who wants a guided path rather than a blank practice page.
AI practice tools
Big Interview-style practice tools help candidates record answers, replay them, and identify areas to improve. This is especially useful when you know what you want to say but struggle to deliver it under pressure.
A strong practice routine includes:
- Choosing questions by job type or interview category.
- Recording answers without pausing or restarting too often.
- Reviewing structure, clarity, pace, and specificity.
- Repeating the same question until the answer feels natural.
- Saving strong examples for later review.
Personalized feedback
Feedback is most useful when it turns vague advice into specific changes. Instead of simply saying “be more confident,” a good interview platform should help you identify what made the answer feel uncertain. That might be a weak opening, missing metrics, unclear ownership, or a conclusion that does not connect back to the role.
Skill building
Interviewing is a skill, not only a knowledge test. Big Interview is useful when you want structured lessons on common questions, storytelling, confidence, and delivery.
You can then use ExtraBrain as a live and post-session workspace once you begin practicing in realistic calls or mock interviews.
Best for
Big Interview is best for candidates who want a curriculum-style preparation experience. It is especially helpful if you need guided lessons before moving into live mock interviews or real-time interview support.

How to use AI interview platforms responsibly
Know the rules before the interview
Before using any AI tool in a live interview, assessment, workplace meeting, or school context, check the rules. Some interviews allow notes, transcription, or AI preparation but do not allow live assistance. Some assessments prohibit outside help entirely.
If the rules are unclear, ask for permission or use AI only before and after the interview. Responsible use protects your reputation and keeps the interview process fair.
Use AI to improve your thinking
AI interview platforms are most useful when they help you become a stronger communicator. Use them to practice, structure, reflect, and identify gaps. Do not use them to invent experience, misrepresent your skills, or bypass assessment rules.
Good uses include:
- Practicing behavioral answers with real examples from your experience.
- Turning scattered notes into concise stories.
- Reviewing transcripts to find unclear answers.
- Generating follow-up questions to ask the interviewer.
- Improving technical explanations and tradeoff discussions.
Keep ownership of your answers
Even when an AI tool suggests an outline, the final answer should be yours. Interviewers are evaluating judgment, communication, experience, and problem-solving. A polished answer that does not match your real ability can hurt you later in the process.
Use AI as a coach, not a substitute candidate.
Practical interview strategy with ExtraBrain
Before the interview
Use ExtraBrain to organize the role description, your resume, likely interview topics, and company research. Ask it to generate practice questions for the specific round. Then practice aloud and review the transcript for weak examples, missing metrics, or unclear reasoning.
During the interview
If live AI assistance is allowed, use ExtraBrain to help track the conversation, capture transcript context, and structure your thoughts. For coding and system design interviews, use it to keep edge cases, constraints, and tradeoffs visible while you explain your reasoning. For behavioral interviews, use it to stay anchored to concrete examples.
After the interview
After the session, review the transcript and notes while the conversation is still fresh. Look for questions you answered well, questions you struggled with, and follow-up topics to prepare for next time. You can also draft a thoughtful thank-you note based on the actual topics discussed.
This after-interview review is one of the most underrated parts of interview preparation. It turns each interview into better data for the next one.
