Less than a single hour with a prep coach. More effective than a semester of them. Start today, cancel whenever.
Flexible — pause or cancel any time.
For people serious about landing the role.
7-day money-back guarantee · No ads · No upsells · No credit-card-required trial games
Not in the "enter your card and we'll charge you in 14 days" sense — we think that's a trap. Instead we offer a full 7-day money-back guarantee: subscribe, use everything, and if the first week doesn't move the needle on your prep we'll refund you, no questions.
Yes. Cancel any time from your dashboard — your subscription ends at the close of the current billing period. You can also pause to freeze your spaced-review schedule while you're on vacation or in a sprint.
Because once the graph and grader exist, each additional learner costs us almost nothing. We'd rather charge a fair price and have a learner for years than gouge them into unsubscribing after a month.
Not yet. If you're a company that wants to sponsor your engineers, reach out via the sign-in screen after trying it yourself — we'll sort something out.
Your graph state, review queue, and history stay on your account. If you re-subscribe later, you pick up exactly where you left off — spaced review and all.
The first session is 30 minutes. By the end, you'll have a map of where you stand — and a clear path to interview-ready.
