Who is this Storage Engineer interview plan for?

It gives you a 60 min script to follow in the conversation — 8 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.

How is the 60 min split up?
Introduction (5 min), Technical Q&A (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.
