Had the initial screening interview and got invited back for the second one. I was asked to do a three part case study. The first part consisted of a data analysis that was difficult, even when I researched and asked my colleagues who have more background in stats than I do. I was asked questions that were worded badly to get an answer out of me that "wasn't what she was looking for". Some questions I was asked as if I should have known what it's like to work at the company which was frustrating. Interviewer was also condescending.
