Domande di colloquio presso Focal Systems

First step was half HR, half technical. The HR part was the usual introduction. The technical part was quite interesting. In the HR portion, the (non-technical) interviewer evaluated your theoretical knowledge by comparing your answers to those prepared by the technical team. For instance, if you place two light sources on the sides of a roller object, the shadow could either be a square or a circle. If asked about the shape of the shadow, both answers would technically be correct. I believe the purpose of the technical part is to assess whether your answers align with the expected responses. You might be correct in your reasoning, but your answer may not match the predefined 'spreadsheet' answer. If you succeed in the technical part of the HR interview, the next step in the technical section is live LeetCode coding for the remaining time.
