The biggest advantage is probably that the security guard was super friendly...

Other than that, nothing else (awkward)

I clearly applied for a procurement position, but only found out on the day of the interview that it was for a procurement assistant position.

The department head seemed very decisive and forceful, and spoke very quickly and sharply.

Overall, the interview experience was very bad. It was a huge waste of my time. HR should have screened this beforehand.
