OfferBull is an AI interview practice app. It runs realistic, voice-based mock interviews tailored to your resume and target role, and gives you real-time coaching so you can build clear, confident answers before your real interview.

Which platforms are supported?

OfferBull is available on iPhone, iPad, and Android. Mac and Windows versions are coming soon.

Is it allowed to use OfferBull during a real interview?

It depends on the employer, and many don't allow it. A growing number of companies prohibit AI assistance during interviews. OfferBull is built for preparation: use it to practice before the interview, and follow each employer's rules on the day.

Everything you need to prepare, in one app

AI Mock Interviews

Practice in a realistic interview setting. OfferBull asks questions out loud, listens to your spoken answers, and follows up the way a real interviewer might. That way you're not hearing a question for the first time on interview day.

PRACTICE

Practice for Your Role and Your Resume

Upload your resume and tell OfferBull the role you're targeting. Practice sessions are tailored to your experience and the job's requirements. Practice sets cover common roles across industries, and the question bank is refreshed regularly to keep up with hiring trends.

SECURITY

Build Clear, Structured Answers

Turn rough stories into answers that land. OfferBull helps you organize your thinking into a clear, logical structure, such as Situation, Task, Action, Result (STAR) for behavioral questions, so you can say more in less time.

LANG

Real-Time Coaching While You Practice

Fast, accurate speech recognition transcribes what you say as you say it. Real-time suggestions help you get unstuck, recover from a blank moment, and try a stronger version of your answer on the next attempt.

PLATFORM

Practice in English or Chinese

Prepare in the language your interview will be in. This is especially useful for international students and bilingual candidates who want extra reps in English.
