Endeavour Foundation interview questions

There were two interviews each consisting of a two person panel. The first interview went smoothly, and the second interview was mostly smooth with a bit of confusion due to the general manager not being familiar with the terms they were using and other businesses. Talent Acquisition then asked for a reference check and stated that I was the preferred candidate. The interviewers stated that they were still interviewing candidates however, which was unusual. They also stated that references should be "as long as possible" for a "better score" through the automated system they were using. Very positive references were provided, and the organisation claimed to have a concern about "a few things" relating to autonomy in the reference statements, which very was confusing to myself and my referees, with my referees even offering to discuss with Endeavour further about what the issue was since they had clearly interpreted something incorrectly. They have been silent since.
