Pretty straightforward interview process. No official guide. Process took several months with different panels. Interviews were all Zoom based for 30 minutes at a time. Mostly around experience, but not necessarily START type. It really depended on the interviewer and what they were interested in. For example, one was a keen Excel user so he asked a lot of questions about Excel. Another asked why business fail.
