It gives you a 60 min script to follow in the conversation — 6 questions with what each one is for and the signals to score against — so you are not writing the round from scratch the night before.

This round is focused on: Design Skills, Creativity, Attention to Detail, Past Projects, Innovation. It works through Portfolio Review and Closing, scoring against 37 observable signals, with follow-up prompts on all 6 questions for going deeper where an answer is thin.
How is the 60 min split up?
Portfolio Review (50 min), Closing (5 min). The timings are there so the round stays on schedule and every candidate gets the same shape of interview — which is what makes two candidates comparable afterwards.
