Some of the questions they ask you during the interview really don't make any sense. They ask you to rank certain things like student GPA, Socio-economic status, class attendance... but don't tell you in what context you're supposed to be ranking them. It's really strange. They also have you analyze some data sent to you in a spreadsheet, but the data also doesn't have much context, so it's practically impossible to draw conclusions from. I'm honestly not sure if they don't realize that data can't be analyzed without certain pieces of information, or if they want you to tell them it can't be analyzed so they know you're not just faking answers.
