Behavior Analyst Certification Board Administrative Assistant interview questions

The process was efficient and professional. However, I am confused about the 'in person interview'/'meet and greet'. I interviewed with the Recruiter, then shortly after, the Office Manager and team I would be supporting, all via phone call and virtually. After that, I was invited into the office for final interview and 'meet and greet'. This was a 90 minute meeting where we sat in a large conference room and discussed the remodel of their exceptionally nice office building. I was given a FULL tour as well as a FULL detailed layout of the remodel. By this point, I felt I was to be offered the position as the tour and remodel overview was super personal. But WAIT! As I am leaving the interview, they want one last item. A written paragraph, 200 words, about my experience that day! Okay, not a problem. I sent that immediately after I returned home, only to get a call a few days later stating they are going with someone else. :( That was crushing. Don't take people thru that deep of a process if they are not the chosen one. It became too personal! I do appreciate however, that they called and didn't just send a cold email! About 3 weeks later, I saw the same exact position posted, but this time it was called an Ethics Admin Assistant. Hmmmm
