FAQ

The 3 things candidates want clear before a live interview

Candidates usually want clarity on setup, privacy boundary, and fit, then a free trial before deciding whether to bring it into a real interview.

Validate the share-safe setup

Proof matters more than slogans. Rehearsing the exact screen-share and stealth path on your target platform is what reduces surprises in a live round.

Know the privacy boundary

Local-first by default. Sensitive context stays on-device wherever possible, with encrypted transfer paths and a clear privacy policy you can review first.

Try it free before you decide

It is not only for coding roles. Whether your loop is coding-heavy, system design, behavioral, or business-facing, start with the free tier and decide after trying the core workflow yourself.

No. Interview AiBox was first shaped around software engineer workflows such as coding rounds, online assessments, and system design, but it is not limited to technical roles anymore. We have also done substantial optimization for product, operations, sales, consulting, customer success, and other non-technical interviews, especially for behavioral rounds, business conversations, case-style answers, answer structure, and real-time prompting.
