Volkswagen Group Fullstack Developer interview questions

I applied for this job in December 2022. First you get a 20 minutes cognitive test which you need to clear. After clearing cognitive test, I received an email for get-to-know interview from person who is part of Group Data & AI Products (Data Lab Munich). The Interview was for 20 minutes and they told me that I have to do some take home coding task which needs to be done in 3 days. As a result, I received the coding task in a pdf file which has no exact requirement. It says choose your tech but Python 3 preferred and do the backend, frontend, unit tests, end to end test, design diagrams, docker deployment, application logging and documenting (all in 3 days). Also mentioned do what you are best at. (This line I didn't like, Since they ask you to do lot of things, they can reject you for anything even though you did what you are best at). I had some questions which I asked them but they answered to it after two days by that time I assumed and did most of the ground work. I didn't sleep properly for three days and somewhat submit the task doing backend, frontend, design diagrams, unit tests, docker deployment. (I did all this right before Christmas). Now I am in February and I have dropped two-three emails but didn't get any answer at all. Not even a rejection email. So, if you get an interview from this team please think twice before even taking coding task. Simply a waste of time.
