adidas Manager, Digital Analytics interview questions

First interview as intro call with basic questions such as "why Adidas" and the promise to get back in a week. After three weeks got an email with negative feedback.

The process started with an HR call and afterward a call with the team and then a case study follows up. For me there were a lot of red flags; - Process took more than 2 months. - HR call started with mentioning how chaotic the company at this moment. - Before case study, I have been told it is the final stage but there was an additional surprise interview step indeed. - Little to no feedback even though you spent a lot of time on the process. - It takes three emails to get a response and communication is so poor. Mostly no response at all. Lastly, I have been asked to have another step after the case study but got a response from HR something was wrong with the case study. When I asked why did I got an invite for a step after then they don't know why. Personal Opinion: If you would like to have a peaceful state of mind during the process and feel valued then don't go for it.
