Interview Practice Books

For AI Interview Preparation and Interview Practice Books, first-party activity records help us understand page visits, resource use, study sections, saved-practice actions, test starts and submissions, feedback requests and checkout steps. These records use browser/session identifiers and may be linked to your signed-in account. Activity events do not contain your answers, code, execution output or copied reading text. Saving answers for your course history and requesting optional AI feedback are separate features described below.

Timed-test answers are automatically saved to your account while you work. We retain your answers, test dates, payment identifiers and requested feedback to provide your history and enforce access and usage limits. Do not enter secrets, confidential material or sensitive personal information.

Python coding answers are saved as part of your test. Execution happens in a browser worker within an isolated frame using Pyodide runtime files downloaded from jsDelivr. We do not send code to an external compiler. Custom standard input, terminal output and sample-check results stay temporary in the browser; they are not saved as an official grade. Leaving the question, stopping execution or reaching the test deadline ends the running worker.

During an active Practice Books exam, the browser reports when the test tab becomes hidden. We save a random event identifier and server receipt time with your attempt, up to 1,000 events per attempt. We do not record other browsing destinations, camera footage or screen captures. These browser-reported events are best-effort practice reminders, not proof of cheating, and do not change your score, pause the timer or automatically submit the test. Events are not sent to an AI provider.

Only if you explicitly request AI feedback, we send the written answers, questions, rubrics and sample answers to OpenAI. We do not include your account name or email in that request. We request that the response is not stored through the API response-storage feature; the provider's own processing and retention policies still apply. Feedback is saved to your account and is fallible learning guidance, not a hiring assessment.

After submission, use Delete my answers and AI feedback to remove your answer text, tab-change events and stored AI feedback. Minimal attempt dates, test identifiers and daily usage records remain, so deletion does not reset usage allowances. Purchase records remain for payment and support needs. For account-level deletion or inaccessible refunded attempts, contact us through support.
