PPD Clinical Data Manager interview questions

The interview process was unorganized and ridiculous. I was told to arrive at the wrong building, only to be shuffled back and forth between buildings. I interviewed with 4 different groups of people. They all asked behavioral type questions (tell me about a time when ... blah blah ). Some of the groups of people even asked the same exact questions. They didn't ask me to talk about my overall experience. When I asked them about the job responsibilities, each group of people told me different things. I was confused and exhausted after several hours of being drilled. It was not constructive at all.
