"A standard, pleasant interview with some basic questions about previous experience, motivation, and hobbies. The interview lasted about 20 minutes. After a few days, I received feedback that I passed the initial selection and that we needed to schedule a technical interview. After that, they never contacted me again."

You apply to Unicredit thru connections or you have to find a job on their website portal and later if you are shortlisted you'll be contacted soon for the first round. However the evaluations may take time, because they don't hire all around the year, so they need to check the availability and later shortlist you.
