Kantar Research Analyst interview questions

Super day in NYC. The office was very nice, but the people were a bit serious/cold (probably because they were doing 20 interviews back to back). Interview itself was okay. Worst part was that I never got an email if I got the next round or not. I would think I huge company like Kantar would be professional and send a rejection email. I've spoken to others since the interview who have shared similar experiences about the terrible communication. Probably dodges a bullet anyway. They don't pay enough for the amount of work you get.
