I was called for an interview after a few days from the application. The interview took place on MS Teams in front of three employees. After a week I received the feedback that they had chosen another candidate. They were kind enough to let me know why they didn't choose me by calling me in the following days and give me a thorough feedback on my interview. There I learnt that I had been picked among the 6 most fit candidates out of 100, but there was just one place for the unit I applied to.
