I had an interview with the Human Resources Department of SumUp, I prepared myself by reading about the company and by watching youtube videos of interviews with human resources. Basically, all the questions were the same as those I saw on youtube, videos. But sadly I did not pass the interview, so when I asked about the mistakes I made in order to improve myself for other interviews. SumUp did not offer me feedback I understand there are a lot of candidates but It would be nice to have that feedback.
