Bayer Data Science interview questions

The interview was supposed to take through Skype but the interviewers were 10 mins late and there were technical problems from their side so they requested me to call them via phone instead (+ costed 5-10 mins more). As they scheduled another interview right after mine, they put me under time pressure by asking all questions they planned and cutting me off many times. After the interview, they offered me an "update call" almost a month after the 1st interview. In this update call, they said that they would inform me about my application status in another 2 weeks, and if I passed the first round, I would be then invited to the second interview in 1 and a half month. However, I did not hear anything from them from then (2 months already). In overall, my impression on this recruitment is that they are poorly organized and did not do as what they promised. They kept the candidates hanging without a proper answer (in total almost 3 months from the 1st interview). Even though I can assume that I did not pass the interview, I still need a transparent response.

This position is located at the research park at the University of Illinois at Urbana-Champaign. The employer asked me to make a presentation of one of my projects and they mainly asked some behavioral questions. They didn't ask any technical questions except some questions about the project I presented. Overall, it was easy but it does require some communication skills.
