Gallup Polling Analyst interview questions

I applied to a position online and got a call from HR not to long after (maybe a week). I prepared by looking into a lot about their company at what they do. How my previous experience would relate to what they do at Gallup and so on. I was completely taken off guard by the questions that they asked me, there was no way that i could have prepared. It was entirely a personality test, more of a screening process than an actual interview.
