About Cram24
Cram24 is a focused 24-hour interview cram. We exist because the night before an interview is mostly wasted on panic — re-scrolling problems you already know and avoiding the ones you don't. Cram24 replaces that with an hour-by-hour plan, a checkpoint at every block, and a readiness score, so your last day goes to the material that actually moves your odds.
What Cram24 is
Cram24 paces you hour-by-hour through the highest-ROI material for a software interview — patterns and complexity, the Blind 75 core, system design, and behavioral stories. Each block ends in a checkpoint quiz; you clear it to unlock the next one. At the end you get a single readiness score and a topic-by-topic breakdown of what's strong and what's worth your last hour. A 24-hour countdown runs on the server, so the plan keeps pacing you even if you close the tab.
Accounts are free: the full topic plan, reference notes, and your dashboard cost nothing. The guided sprint — the checkpoints, the pacing, and the readiness score — is a single one-time unlock, not a subscription: $4 for 24 hours of full access. The free reference curriculum covering data structures, algorithms, system design, and interview behavior is open to everyone.
Why we built it
The problem with the night before an interview isn't usually effort — it's triage. With one day left, the worst thing you can do is grind random problems and hope. The highest-value move is to spend your remaining hours on the few topics most likely to come up and most likely to trip you, and to walk in actually knowing where you stand instead of guessing.
We can't make you a different engineer overnight, and we don't pretend to. What we can do is make your last day strategic: a concrete plan, a checkpoint that proves you actually have a topic before you move on, and an honest verdict at the end. That's the difference between walking in anxious and walking in calm.
How we approach the work
Three principles guide what we ship:
- Highest-ROI first. The plan is built around what most reliably shows up in real loops and most reliably moves your odds — not exhaustive coverage you can't finish in a day.
- An honest verdict. The readiness score is earned from your checkpoint results, not vibes. If a topic is weak, we tell you plainly so you can spend your last hour where it counts.
- Free at the core. The plan, reference notes, and your dashboard live on the free tier. The one-time unlock is for the guided sprint itself — the pacing, checkpoints, and score — not for gating the basics.
How we keep it accurate
Plan material and checkpoint questions are written or reviewed by people who have run real interview loops. We update topics as question patterns shift — new common system-design prompts, changes in what panels weight — and date-stamp pages so you can see when content was last reviewed.
