lvlUp gives you a timed system design interview on paper and grades the pages you draw. It hands you one real system design question, starts a 35 minute clock, and walks you through the four steps of the ritual. You work it out with a pen, photograph your pages, and send them in. A minute later you have a debrief: a score out of 100 across six dimensions, the evidence behind each one read off your own page, what worked, the gaps, and one drill to run next. THE RITUAL Four steps, one clock, no restarts. Framing, 5 minutes. Restate the problem. Agree on scope, users and success in one sentence. Estimates, 10 minutes. The five slots: volume, requests per second with a peak multiplier, payload and egress, concurrency, and the judgment line. Design, 15 minutes. Boxes and arrows, only after the numbers exist. Parking lot, 5 minutes. Every open question lands here, and then you close them out. The clock shows the time left in the current step and the time left overall. In the last minute of a step the digits turn warm. That is the only thing on the screen that moves. WHY PAPER A real interview is a pen, a page and a clock. There is no editor, no autocomplete and no undo, so practising in one teaches you reflexes that will not be there on the day. lvlUp keeps the medium and takes the marking off your hands: draw it, photograph it, send it. THE DEBRIEF It opens with the single biggest gap, because that is the one thing worth fixing on the next attempt. Under it sits the DESIGN axis and its six rows: requirements and constraints, high level architecture, data model and APIs, scaling and bottlenecks, reliability and tradeoffs, and clarity of the drawing. Each row carries its score and the line from your page that earned it. Then what worked, then the drill. PROGRESS Every attempt is kept in order with its score, so the change is something you can read rather than something you have to take on trust. WHO IT IS FOR Engineers preparing for a system design round, and anyone who has read the theory and still goes blank in front of a blank page.
