NovaInterviewer vs Big Interview is a comparison of two AI-powered interview preparation tools that take fundamentally different approaches: one calls your phone and runs a realistic, graded mock interview for a specific job, and the other is a browser-based video training platform with a structured curriculum and AI delivery coaching. They serve different learning styles, and picking the right one depends on whether you want quick, realistic interview reps with feedback on what you said, or a comprehensive, course-like program that teaches you how to interview from the ground up.
Quick answer: Nova Interviewer calls your phone and runs a realistic, spoken mock interview for the exact job you paste in, then grades your answers with coaching notes on what to fix. Big Interview is a browser-based video training platform that combines a structured interview curriculum of video lessons and practice exercises with AI feedback on your delivery -- filler words, pacing, and eye contact. Choose Nova Interviewer if you want to practice answering real interview questions out loud and get feedback on the substance of your answers. Choose Big Interview if you want a step-by-step training program that teaches you how to interview well across question types and industries.
What is Nova Interviewer?
Nova Interviewer is an AI mock interview platform that calls your phone and runs a realistic, spoken interview for the exact role you are targeting. You paste a job description, the AI calls you, asks questions tailored to that role, follows up when an answer is vague, and then grades you with a score and specific coaching notes on what to improve. It is built to recreate the pressure and format of a real phone interview so you walk in having already rehearsed. Your first mock interview is free. Keep practicing with Core at $9.99/month (3 mock interviews per month); Pro is $19/month for unlimited. Try your first mock interview free or see candidate pricing.
What is Big Interview?
Big Interview is a browser-based interview training platform that combines a structured curriculum of video lessons with an AI practice tool. It was designed to teach job seekers how to interview through step-by-step instruction, covering question types, answer frameworks like STAR, and industry-specific scenarios. Its AI feedback focuses on delivery: filler words, pacing, eye contact, and other public-speaking metrics rather than evaluating whether the substance of your interview answer was strong. It also includes a large question bank organized by industry and role. Big Interview is used by individuals preparing for interviews as well as by universities and career centers that license it for their students. See Big Interview's site for current details.
Is Big Interview free, and how does pricing compare?
Big Interview does not have a free tier. Its pricing is approximately $79 per month or $299 for lifetime access, which gives you the full video curriculum, AI practice tool, and question bank. Some universities and career centers offer free access to students through institutional licenses, so check with your school's career office if you are a student. For comparison, Nova Interviewer's first mock interview is free. Keep practicing with Core at $9.99/month (3 mock interviews per month); Pro is $19/month for unlimited sessions. Big Interview is a higher upfront cost but includes a full curriculum; Nova Interviewer costs less per month and gives you realistic, phone-based mock interviews on demand. Check Big Interview's pricing and Nova's pricing for the most current numbers.
Does Big Interview do phone-based mock interviews?
No. Big Interview's practice tool runs in the browser with a webcam, so you record video responses to pre-written questions rather than receiving an actual phone call with back-and-forth conversation. Nova Interviewer, by contrast, calls your phone and runs a spoken, interactive conversation with follow-up questions when your answer is vague. If you want to practice answering out loud with the pressure of a real phone call and an interviewer who pushes back when you give a weak answer, Nova Interviewer's format is closer to the real thing. If you prefer recording video answers on your own schedule and reviewing them, Big Interview's format may suit you better.

Which gives better interview preparation?
It depends on your learning style and how much time you have. Nova Interviewer is built for efficiency: paste a job description, get a phone call, answer realistic questions, and walk away with a grade and specific feedback on what to fix. It is the faster path if you want to know where your answers stand and improve them through reps. Big Interview is built for depth: it teaches you interview skills systematically through video lessons, explains frameworks like STAR in detail, and gives you a large question bank to work through at your own pace. It is the stronger choice if you are new to interviewing, changing careers, or want to understand the theory behind good answers before you start practicing.
For delivery coaching, Big Interview's AI feedback on filler words, pacing, and eye contact is useful if those are your weak spots. But it does not grade whether your answer to "tell me about a time you resolved a conflict" was actually a strong answer. Nova Interviewer evaluates the substance: did you give a specific example, did you state a clear result, did you answer the question or dodge it. If your answers are solid but you ramble or avoid eye contact, Big Interview's delivery coaching helps. If you do not know whether your answers are good, Nova Interviewer's content feedback is what you need.
How to choose between NovaInterviewer and Big Interview
Answer these three questions:
- Do you want a quick practice session or a full training course? If you have an interview coming up soon and want to rehearse realistic answers for that specific role, pick Nova Interviewer. If you have time and want to learn interview skills systematically from the ground up, pick Big Interview.
- Do you want feedback on what you said, or how you said it? Nova Interviewer grades the substance of your answers and tells you what to fix. Big Interview coaches your delivery -- filler words, pacing, eye contact -- but does not evaluate whether your answer was strong. If you need both, start with Nova Interviewer to find your weak answers, then use delivery coaching to polish how you present them.
- Do you want a realistic phone interview format? A phone call from Nova Interviewer feels like a real phone screen, with back-and-forth follow-up questions when your answer is vague. Big Interview has you record video answers to pre-written questions, which is useful for self-review but less like a real interactive interview. If you want to experience the pressure of a real conversation before the stakes are high, Nova Interviewer's format is closer to what you will face.
If you are still unsure, the two tools are complementary rather than substitutes. Use Big Interview's curriculum to learn frameworks and build a foundation. Then use Nova Interviewer to run realistic, graded mocks for the specific roles you are applying to. For a broader look at the category, read our comparison of the best AI mock interview tools.
Bottom line: NovaInterviewer vs Big Interview is a choice between a realistic practice tool and a structured training course. Nova Interviewer is the pick for phone-based mock interviews that grade your answers and tell you what to fix, with your first mock free. Big Interview is the pick for a comprehensive, course-like program that teaches you how to interview through video lessons and delivery coaching. If you can, use both: Big Interview for the curriculum and foundations, and a graded phone mock from Nova Interviewer (first mock free, then Core at $9.99/month) to know where you stand before the real call.
