i4 Insight Senior Fullstack Developer interview questions

I was spotted by a head hunter for this role. The process took about a 1 and half of a month. They said they are looking for fullstack developers with Python, fastAPI and React so that matched my interest. There were 3 HR meetings(headhunter, manager and architect) for the cultural fit. On the two latter they asked me some technical questions regarding computer science and machine learning, as well as about my experience regarding my cv. There was a 1 technical interview, where I had to implement an algorithm in Python. This was rather unusual to not have any technical questions regarding React, CSS Redux or fastAPI knowing that an interview was for a fullstack role.
