quick verdict
pick based on what you actually need.
choose interviewprep if
you want job-specific prep, fast
you have an interview tomorrow. you open the job posting, click the extension, and get 5 role-specific likely questions with STAR prompts and a company research card — in under five seconds, no copy-paste, no account, no subscription needed for casual use.
choose big interview if
you want structured video coaching
Big Interview includes AI feedback on your video practice answers, a question library, and guided coaching paths. starts at $79/month. better for methodical long-term preparation and building interview confidence through repetition, not for fast one-off prep.
choose final round ai if
you want real-time interview assistance
Final Round AI listens to your live interview and suggests answers in real time. different use case — it's assistance during the interview, not preparation before it. starts at $24/month. choose it if you want in-call help; choose interviewprep if you want to walk in prepared.
use chatgpt manually if
you already have a good prompt workflow
ChatGPT is free and flexible. if you have a reliable prep prompt saved, copying the job description in and iterating works fine. the tradeoff: 5–10 minutes of manual setup per posting vs. one click in interviewprep. interviewprep is faster; ChatGPT is more flexible for off-script questions.

why it matters
generic questions vs. job-grounded questions.
the most common problem with interview prep is misalignment — you practice generic answers and walk into a role-specific interview unprepared for what actually gets asked.
most prep tools use question banks organised by role type or industry. these are useful for building a repertoire, but they don't adapt to the specific responsibilities, stack, and culture signals in the actual posting you applied for. a senior product manager role at a Series A fintech has different likely questions than the same title at a regulated bank — even though the role type is the same.
interviewprep reads the live job description and generates 5 questions based on its specific language — responsibilities, requirements, qualifications, and any company signals visible in the posting. the STAR prompts are written against the same source, so your answer preparation is grounded in what the interviewer is actually thinking about, not a generic coaching script.

What is the difference between interviewprep and using ChatGPT manually?Manual ChatGPT prep requires copying the job description, writing a prep prompt, asking for STAR format separately, and running additional prompts for company research — 5–15 minutes per posting. interviewprep does all of this in one click directly on the job posting page: 5 role-specific questions, STAR prompts, and a company card. The result is the same information with less friction. interviewprep's free tier gives you 5 briefs per month without requiring a ChatGPT subscription.
