What is Big Interview, and what does it do?
Big Interview is an interview training platform: video lessons, a practice simulator and AI feedback on answers you record. Its homepage says it was co-created with career coach Pamela Skillings. It sells to job seekers directly and to career centers, workforce agencies and nonprofits. Everything it does happens before your interview.
The Interview Simulator page says you can "Access over 10,000 real-world interview questions" sorted by industry, role and seniority. You answer on camera, and the AI reviews your delivery. An answer builder walks you through structuring behavioral, technical and situational answers.
Big Interview also sells a resume tool, Big Resume, and lists LinkedIn profile help in its three-month plan. Its pricing page says the platform has helped "over 2 million people." That figure is the company's own and wasn't checked for this review.
How much does Big Interview cost compared with Prept?
Big Interview's cheapest plan is $39 for a 30-day subscription, and Prept's is $29 a month. Both prices were checked October 24, 2026, on each company's own pricing page. Big Interview also sells three months for $99 and lifetime access for $299. Prept sells a quarter for $69 and has a free tier.
Big Interview's personal pricing page lists three plans. Interview BootCamp is "$39/mo" for a "30-day subscription." Interview Accelerator is $99 for three months and adds resume feedback and LinkedIn help. Interview Pro is "$299" with "ONE FEE. LIFETIME ACCESS."
Its refund promise is generous: "If you don't see the results within 30 days, we will give you a 100% refund." The FAQ on the same page says you cancel "your membership renewal through your account page," so the 30-day plan renews until you stop it. No free tier is shown.
Prept's pricing has a free tier with no card: your resume reviewed in full, 1 job posting checked, 1 application tailored, 1 interview hour transcribed and debriefed, and your headline and LinkedIn. The paid Search plan is $29 a month or $69 a quarter. It starts with 7 days free with a card, and nothing is charged until day 8.
Over three months the gap is $99 against $69. Lifetime access at $299 costs the same as about 10 months of Prept at $29. Which one is cheaper depends on how long your search runs and whether you need practice or review.
How do Big Interview and Prept compare feature by feature?
They cover different halves of the same problem. Big Interview trains you before the interview with lessons and recorded practice. Prept reviews a real interview after it, then tailors your resume to each posting. The table uses the same rows on every Prept comparison page, with Big Interview's cells taken from its own site on October 24, 2026.
| Feature | Prept | Big Interview |
|---|---|---|
| Help during a live interview | No, by design (analysis after the call, never during it) | Not offered |
| Practice or mock interviews | No | Yes: an Interview Simulator with over 10,000 questions and AI feedback on recorded answers |
| Debrief of a real recorded interview | Yes, transcribed and debriefed, quotes the moment you lost the room | Not offered; VideoAI reviews your practice answers |
| Resume review with an ATS score and reasons | Yes | Big Resume's ATS Fit Checker shows what to adjust; ATS Fit scoring is listed on its school page |
| Resume tailored to each posting | Yes | AI helpers write summaries, bullets and skills lists for a target role |
| Every claim checked against facts you confirmed | Yes; numbers you can't stand behind are left off rather than invented | Not stated on its site |
| Job posting fit check | Yes, scored with the reasons | The ATS Fit Checker compares your resume with a job description |
| LinkedIn profile help | Yes (headline free, full profile on Search) | Listed in the $99 three-month plan |
| Job application tracker | No standalone tracker; each application keeps its tailored resume and rounds | Not stated on its site |
| Free tier | One of everything, no card | None shown; 100% refund within 30 days |
| Lowest paid price (USD) | $29 a month, or $69 a quarter | $39 for a 30-day subscription |
| Pick it if | You've had real interviews and want to know what went wrong in them | You want a structured course and video practice, or your school already pays for it |
The Big Resume page describes the ATS Fit Checker as analyzing "your resume against real job descriptions" and showing "what to adjust." It doesn't say whether it checks your figures against anything. Prept's tailoring only uses facts you've confirmed.
Why is a university login Big Interview's biggest strength?
Many people can use Big Interview for free through a school, a workforce agency or a nonprofit that pays for it. Big Interview's higher education page says "700+" institutions use it. If you're a student or recent graduate, ask your career center before you pay anyone, including Prept.
The higher education page describes what a career center gets: "1,000+ real-world practice sets," AI feedback on every recorded answer, and a way for advisers to review answers and "leave your own feedback." It integrates with Canvas and Google Classroom. So a student can practice alone and still get a human's notes on the answers that matter most.
The pricing page quotes one user saying "My alma mater gives students and alums access to Big Interview for free." That's one testimonial, and access rules vary by school. Your career center will know whether alumni keep access after graduation.
This is the honest case for Big Interview. A free login, a structured course and an adviser who can see your practice is a strong package. No after-the-call tool replaces it.
What does Big Interview's VideoAI feedback cover?
VideoAI watches your recorded practice answers and comments on how you came across. The VideoAI page lists eye contact, posture, facial expressions and filler words such as "um" and "like." It also says it will "Highlight when you've lost your train of thought." All of it applies to practice answers you record inside Big Interview.
The simulator page adds pace and body language to that list, and the school page adds tone and vocabulary. That's useful if your problem is delivery: you speak too fast, look away from the camera or fill pauses with filler words. Seeing it on video is hard to argue with.
The same FAQ makes a bigger claim: "Our users get a job after 4.5 weeks on average." The page doesn't give the sample or the method, so treat it as the company's marketing figure.
What can't a practice tool tell you after a real interview?
A practice tool can't tell you what happened in the interview you actually had. It never heard that interviewer, that follow-up question or the answer that ran three minutes. When the rejection arrives, you're left guessing whether the problem was delivery, content or a story that changed between rounds.
That's the gap Prept fills: analysis after the call, never during it. With everyone's consent, it transcribes a round you recorded and writes a debrief that quotes the moment you lost the room. Before every recording it asks you to confirm the other side knows. If you've never asked, read how to ask to record your interview first.
You can do a version of this without any tool. The free 10-minute debrief template works from memory the same evening. The page on what an interview debrief is explains the method, and it pairs well with Big Interview practice.
Who should pick Big Interview, and who should pick Prept?
Pick Big Interview if you haven't started interviewing, freeze on common questions or get it free through a school. Pick Prept if you're getting interviews and losing them without knowing why. Plenty of people need both: practice before round one, then a debrief after each real round so the next one improves.
If you want practice and money is tight, compare the free options first. Prept vs Google Interview Warmup covers what happened to Google's free practice tool. Prept vs Yoodli looks at a practice tool with a $0 starter plan. The list of free interview feedback tools puts the free tiers side by side.
If you're weighing a live copilot instead, read Prept vs Final Round AI and the employer rules in employer AI interview policies before you buy. Big Interview and Prept both stay out of the live call, so neither runs into those rules.
