Desktop OS - a candidate's simulated first week, quietly scored on how they think, not what they claim.
30 SECONDS INSIDE THE SIMULATION - FROM THE LAUNCH FILM, RENDERED IN CODE
Resumes don't show how someone works under a real week's pressure. Interviews reward performance; work reveals judgment. So the interview became a week of work.



REAL SIM SCREENS · THE DESKTOP MID-FIRE · THE SQL ENGINE RUNNING · THE LOGIN
A hidden evaluator scores prioritization and written thinking as they work.
The hire came from the simulation, not the resume.

Pick a moment. Watch the calls the system makes that no one sees.
EVERY STEP MINED FROM THE REAL BUILD · NOTHING INVENTED
One prompt did produce a version of this - and it is the reason the real one exists.
Two days in, the first playable build: one HTML file with invented app interfaces - a WhatsApp that looks nothing like WhatsApp.
Its default: approximate the apps, invent the icons, ship a stylized demo of an office instead of an office.
the UI of the apps should reflect real UI more accurately - whatsapp does not look like how you coded it. [...] This feels like a toy demo - nothing like a real website - feels really half baked really - dissapointed. [...] this is not a brand new concept - so let us not re-invent the wheel, let us use the current wheel and build on it
That message is why every app is a pixel-faithful clone in real brand hexes - the desktop a proven open-source OS pattern, not invented.
The realism IS the test - you can only measure how someone works if the tools work like the real ones.
