HelloFresh interview questions

Firstly you have a 24 hours task with SQL, Excel, Python the aim is to make predictions. the data bas is pretty huge (30 000 datas). First interview to know you better and the way you think. I got a question about how to calculate future profit regarding the prediction we have made. Second with precise technical questions, they want to know if you can vulgarize things Final interview with the manager.

I had 2 people conducting interview in the same time. Interviewers in the office assured me I would receive an answer within 2 weeks. One year later still no answer hahaha. I find it quite unprofessional, once you are called to the office, and promised by two different people to at least receive a notification of yes or no, yet completely ignored.
