PDF and EPUB, and the code. Download them any time.
PRICING
iOS or Android Interview Training. $59 once.
Pay once. The book and the code stay yours.
For 90 days: Guided Practice
A 7, 14 or 30-day route, twelve simulations per platform and the online reader.
Your attempts, side by side
The baseline, the repair target and the changed-constraint retry, kept together.
What do I get on day one?
The interview book and companion code to keep, plus 90 days of Guided Practice. The book is PDF and EPUB; the companion code is a download. Guided Practice opens with a first mission and a worked example, then a 7, 14 or 30-day route, twelve simulations and the online reader. The 90 days start on the day you pay.
After 90 days: what stays?
You keep the PDF and EPUB books and the companion code, and can download the current edition any time. Guided Practice and the online reader end; your attempts stay readable, read-only, for 12 months: sign in to browse, export or delete them. After that they are deleted. Guided Practice continues only if you choose the optional membership ($14.99 a month or $149 a year, renews until you cancel). Nothing renews unless you start it.
Is it a subscription?
This purchase does not start a subscription. One payment. The membership ($14.99 a month or $149 a year) is a separate choice, only if you want Guided Practice to continue after 90 days.
Is there a readiness score?
No readiness percentage, title prediction, or offer promise. The work is in the evidence: make an attempt, find the consequential gap, and test the repair.
Can I ask before I buy?
Yes. Write to [email protected].
Can I read some of the book first?
Yes, the free sample is the opening of the real book: iOS sample or Android sample.
