The whole answer.
Every problem comes with the intuition, a traced example and the code. Every design comes with the diagram you'd draw on the whiteboard.
Fair questions.
Can I get a refund?
No, sorry. Premium is consumable content: every guide and worked answer opens the moment you pay, and what you’ve read can’t be handed back, so purchases are non-refundable. That’s why every guide’s overview and several of its lessons are free: read them first and judge for yourself. You can cancel the monthly or yearly plan anytime and it won’t renew. Charged twice or by mistake? Email contact@interviewlegend.com and we’ll fix it. The details are on the refund policy.
What if I don’t get the job?
No prep can promise an offer, and we don’t. What we promise is the questions your company is asking right now, each with a worked answer, and a guide we keep current every month.
What can I read for free?
Every guide’s overview and a few of its lessons, 872 lessons in all. Pick a company and start there. Premium opens the other 837.
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.
