I build ArcLab Sim, a free browser-based practice experience for the first week of a software engineering job. You join a fictional restaurant-booking team. On Day 1, you orient yourself in simulated workplace tools, check the running app, make a test booking, and reply to your simulated manager. Later days move into a real browser-run Next.js/TypeScript codebase, code changes, tests, and simulated review. A design choice I am testing: Day 1 gives more guidance than the later tasks. That may help a new developer get started, but too much instruction could remove the uncertainty that makes a first assignment feel real. If you know some JavaScript or have onboarded a junior engineer, could you try Day 1 at https://sim.arclab.app/play on desktop Chrome or Edge and tell me: which step could lose some guidance without making the next action confusing? What workplace cue is missing? A specific screen or moment would be more useful than a general rating. Individual access is free and needs no account. I work on ArcLab Sim.
