I did two parts of the interview, the first with a recruiter who was very good and we talked a lot about the company and my career, and the second part was technical, which consists of: 1 - A project to develop (backend and frontend) 2 - 20 technical questions 3 - 3 technical challenges (code) With a deadline of two days to deliver. After spending 14 hours a day doing the process I submitted it and it took 20 days to receive a generic response that I was rejected, I asked for more details to understand how I can improve for future interviews and I was never answered. The process is extremely amateur and without care about the interviewee.
