Does one plan cover every company?
Yes. Every plan opens all 100 company guides plus DS&A Foundations and System Design 101. You never buy a company on its own.
Can I cancel anytime?
Yes. Cancel the monthly or yearly plan whenever you like and you keep access until the end of the period you paid for. No hoops.
Is lifetime really for good?
Yes. One payment, no renewal, no expiry, and every guide we add later is included.
How is this different from LeetCode?
LeetCode gives you problems without direction. Each guide here is about one company: the problems its candidates report, the system designs it asks, its behavioral round and how the loop is scored.
