Uber UberEATS Restaurant Representative interview questions

There were two short interviews with a rather simple 'creative task' inbetween. The atmosphere during the interview is friendly and questions are rather simple and predictable, although you need to show that you did some research about the product and the market and that you have a business sense. Also, you should be careful about asking about your role or tasks - they seem not to like these questions, which was a bit awkward to me. However, after the final interview I was supposed to get an answer in 1 or 2 days, but unfortunately got not even a word in 3 following weeks. I find it a bit improfessional for such a well-known company.
