First, I was invited to an online coding assessment. I had 90 minutes for 4 tasks. This was really intense and I barely managed to get the minimum requried points, but I passed. Next, I got a call from my HR ref and we talked about the position and application process. Then, I was invited to two technical interview cases, both lasting an hour. The first one was good, my interviewer was really kind and it felt more like a conversation than a hard test. Nevertheless, there were many things I did not know. He helped me out with questions and hints, but it felt like I did not perform well. The case was about improving the predicted demand of goods for a supermarket so the storage would not overflow and the the supply would not run out too fast. I had to find good metrics and recommend machine learning models to solve the problem. For the ML model, he really drilled me with how exactly to implement each feature I proposed.
