hr screen, 1st interview with coworker, design challenge with 7-day window, follow-up 2 rounds of interviews if pass the design challenge but i didn't pass the design challenge so don't know what's the next step specifically

The interview process consisted of four rounds. It started with a peer deck interview where I presented my portfolio and past work. This was followed by two rounds with hiring managers, which focused on design thinking, problem-solving, and role fit. The third round was with a director, covering higher-level questions around design strategy and impact. The final round was with an HRBP, focused on behavioral and culture fit questions.
