Where Big Interview is better

  • Practice out loud, with feedback. Its voice mock interviews give feedback on how you speak and what you say. Seal the Offer has no AI voice or video practice.
  • Video feedback. It looks at recorded answers for eye contact, pace and filler words.
  • Lessons. It has video and written lessons, and a fast-track module for an interview soon.
  • A big question bank. It has over 10,000 questions, sorted by industry, role and level.
  • A lifetime plan. One $299 payment has no end date. Seal the Offer has no lifetime plan.
  • A set refund window. It offers your money back within 30 days. Seal the Offer looks at each request case by case.

Where Seal the Offer is different

  • The job ad comes first. It lists what to send, file types, page and word limits, the closing date and any rule about AI. Each rule it finds quotes the ad, and our code checks the quote is there.
  • It writes the application the ad asks for. You get a resume made for the ad, and the cover letter, statement or selection criteria it asks for. Our code counts the words and measures the pages. Files come in Word and PDF.
  • Answers are built on your own stories. A kit has 15 answer cards, or 8 to 18 by type of interview. The answers draw on 8 stories from your resume. Where your resume has none for a common question, the answer is an example, labelled as made up. Each card has a memory hook and 2 follow-ups. A story question gets a short STAR answer (situation, task, action, result).
  • It predicts the likely questions. Each card shows our estimate of the chance it's asked.
  • It researches the employer, such as its mission, projects and recent news, with links. You also get a one-page cheat sheet, and the kit as a PDF.
  • You can practise with a friend. Send a link. They ask your questions and rate each answer, with no account.
  • You pay once. Documents for one job are US$12, and an Interview Kit is US$39. Five kits to use within 90 days are US$169. Prices include tax, and nothing renews. In Australia they're A$18, A$55 and A$239.
