About

An honest readiness number for the interview loop you’re actually facing. CruxRounds prepares experienced engineers for Forward Deployed Engineer, Applied AI Engineer, and Solutions Engineer interviews — customer-facing roles where clear technical judgment and communication matter. HOW IT WORKS • Baseline — a short diagnostic gives you an honest starting readiness number, before you’ve studied a thing. • Weak spots — your baseline shows exactly which rounds need the work, so you stop guessing what to study. • Concepts — focused lessons on what each round actually tests: system design, behavioral stories, deployment and model-evaluation scenarios, discovery, and objection handling. • Quick drills — fast recall practice that locks each concept in. • Area loops — rehearse one round end to end with an adaptive interview simulation, until it’s solid. • Full loop — practise every round back to back, timed and scored like the real thing, with a debrief after. The baseline and your readiness score are free. Concepts, drills, area loops and the full loop are included with CruxRounds Pro. THE NUMBER Everything rolls up into one readiness score and a countdown to your interview date. No streaks, no badges, no confetti — just a straight answer to “am I ready, and if not, what do I fix first?” WHO IT’S FOR Engineers who can already do the work and now have to prove it across a multi-round interview loop. If you’ve been deployed at a customer site, shipped models into production, or run the technical half of a sales cycle, this is built for you. One app to prepare for the loop — and go in prepared, with a clear view of what to improve. CruxRounds Pro is an auto-renewing subscription — monthly, quarterly or annual — billed to your Apple Account; manage or cancel anytime in Settings.

A new way in. • The first screen now signs you in, then asks two short questions — no long setup before you can look around. • Every round is free to browse: what it covers, its four steps, and where you stand. • A new Readiness tab: your number, and what moves it. • A quicker readiness check — eight taps to a first result, with your path visible while you finish. • The interview room shows its grade in the room, and you can retry the same question. • Clearer free and Pro: the readiness check and every round outline are free; the drills, the live interviews and the full mock loop are Pro. • Sharper type, better contrast, and one consistent header throughout.
