Milwaukee, WIPosted Oct 2025 · Candidate report, summarized by Dataford

I hit the more “assessment-heavy” path where timing and volume of coding questions mattered, and the process centered on Codility/CodeLive timed tasks over roughly 1–3 weeks.

Online coding challenge (Codility) — A 70-minute test with many LeetCode-style questions; I found them medium-easy but hard to finish all of them.
Extended Codility test — A Codility assessment with 3 questions and 5 hours to complete, using any language in the web app.
Video + skills assessment (timed coding) — Five rounds total: a video interview, then a skills assessment with two timed coding assignments, followed by HR and manager video interviews.
HR screen + CodeLive exercises — After a simple HR screen, I had an hour technical round: part resume/history
