Where Big Interview is stronger
- Depth. A long, structured video curriculum that teaches how to answer, not only what to say.
- A 30-day money-back guarantee, per its pricing page.
- A wider toolkit. Resume and LinkedIn tools sit in the same product.
- Institutions. It serves schools, career centres and workforce agencies, with single sign-on.
Where Readyo is stronger
- Speed to practice. Open the app, answer out loud, get a scored report in minutes, with no course to work through first.
- A conversational interviewer that asks follow-up questions, instead of a fixed list.
- Small commitments. A single interview is $2.99 and a 7-day pass is $7.99, against a 30-day minimum.
- Four languages for the interview itself and the report.
Which should you pick?
If you are new to interviewing and want to be taught, a curriculum like Big Interview’s is the better start. If your interview is days away and you need reps, Readyo gets you answering out loud immediately. Many people will want both: learn the structure first, then rehearse.
Not covered here: we did not test Big Interview’s simulator ourselves, and its pricing page does not say which plans include the AI feedback.
Where Readyo fits
Readyo is an iPhone app for spoken mock interviews. You paste a job ad or type a role, choose the stage, and an AI interviewer asks the questions out loud and follows up on your answers. You answer by voice and get a report that scores relevance (20 %), structure (20 %), evidence and precision (30 %), clarity and expression (15 %), and composure and ownership (15 %), with an improved version of each answer built only from what you said. The interview and the app work in English, French, Spanish and Arabic. Readyo is for practice only: it never helps during a real interview. It is free to download, and interviews are paid: a single interview, a 7-day pass, a monthly plan or Lifetime (prices checked 11 October 2026).
