Simple interview - for that level you'd expect it to be more complex. Two stages - online application but test, then in person interview. In person was group then individual interview. Had to chase them for feedback on interview - feedback wasn't sufficient for personal development and not an accurate summary of how the interview went. At the end of the interview had to provide RtW doc. Interviewer didn't know what they had to scan - took photos of document on mobile device, commented that "I work for Waitrose of course the documents are not going to be straightforward" in an exacerbated tone.
