Submitting application > screening CV > first test > second test > video interview > final interview. This is the whole process for the Milan position, maybe it can change according to the location
After applying through the Otta platform, I had a numerical assessment, then a video interview with 7 different questions and a final assessment day. The assessment day consisted in an Excel exam, a Business Case Study, and a Fit interview. I also got an introduction to several employees.
