Wirtschaftsuniversität Wien interview questions

This was a position for a marketing institute and I was asked to prepare a statistical analysis case using logistic regression/diff-in-diff analysis. We were asked to find a dataset, formulate two hypotheses and answer them using the data and the respective technique.

2 interviews one online one on site. The online interview they call you and ask all about your resume then the on site interview is in front of 4 people, they ask you questions one by one and you suddenly switch to english
