The interview process consisted of 4 stages: an initial HR screening, a case study, a technical interview and a final culture & team interview.
The first interview was about my experiences and motivation to work with HelloFresh. The case study was sent after I absolved another test that had not been mentioned before and is apparently part of the process. Only in the third stage interview, I found out more about the actual position and tasks. The process was a little confusing. I received a rejection, but was offered a feedback call in the end, which I appreciate.
