LexisNexis Legal & Professional interview questions

After a phone screen I finally landed an in-person interview. It was very awkward from the beginning. The hiring manger sent a calendar invite with the location of "My Office." Sure, "My Office" might be recognized by his browser and log in credentials, but nobody else's (remember that this is an IT manager). After emailing for clarification, he didn't reply until five minutes before the scheduled interview. Luckily I had found the headquarters but still didn't know which building, etc. He replied "When you enter the campus there are two buildings on your left. Go to the entrance." This still didn't clarify whether one of the two buildings on the left or the main building. I managed to enter the main building, although it wasn't the one he was trying to tell me, he found me nonetheless. The people were friendly, didn't notice anything cult-like. Pretty standard interview despite being interrupted by someone attempting to deliver an ergonomic chair. I elaborated on my experiences with x, y and z appropriately. The very next day I received a rejection email. Next please.
