Rill · Full-Stack Engineer (New Grad)
Rill is an early-stage startup, and its full-stack new-grad loop reflects that: a take-home or live build where you ship a small end-to-end feature, a round walking through your code and the trade-offs you made, and a scrappy behavioral chat about how fast you learn and ship. There's no algorithm gauntlet — they want proof you can move across the stack (frontend, API, data) and get something real working with limited hand-holding.
