The interview process lasted 2 month. 1,5 month of waiting and 2 weeks of three rounds of interview. First was video call on Teams with HR and manager. They mostly asked personal questions taking turns. Right next day I got invitation to second round. Second round was in person meeting in Vienna office. They asked me to prepare 40 min presentation based on case studies scenarios that they sent in PDF file and gave me 12h. (The case studies scenarios are listed below). The meeting lasted 1 hour and I was waiting 2 weeks to hear back. After 2 weeks, they invited me to the third round in their headquarter in Kremsmünster town, which is 2,5h drive from Vienna. They said it's needed "to get the feeling of the company culture and to meet my potential colleagues onsite". But instead I had a surprise 1:1 interview with the manager of my manager that no one told me about. I did not like this. The manager did not see my CV and asked many irrelevant to my experience questions and did not introduce himself. After that I waited 1 month to receive 2 sentences: "we found a better fit for this position". They did not say "thank you for spending 8h of your day travelling so far away for the last round of interview", or "thank you for investing another day of your life for making presentation and coming to Vienna's office". Nothing like that was mentioned, I felt I'm a number for them. I'm glad I'm not working there.
