I applied through a recruiter. The process took 3 weeks.

A recruiter reached out to me on LinkedIn, and we had a preliminary interview about the position in which we discussed my experiences. Next, they scheduled an architecture interview where they said that the problem-solving process was what mattered and it didn't need to be Nubank's solution. At the time, I had a perception that my solution was correct. Whenever I tried to detail some components better, the interviewers said, "You don't need to go into that level of detail." The next day, I received a standard email saying, "At this moment, we decided not to proceed with your process for this position. For our decision, we considered factors like team needs, seniority levels, and the repertoire of experiences we are seeking." There was no feedback about what went wrong. I felt that if I didn't have the seniority level, they should have seen that on my resume beforehand. For every interview, we prepare and reserve time, especially if we are already working. In summary, I wasted my time. I don't know if they wanted a specific solution. If that was the case, they should have detailed it better instead of saying, "It doesn't need to be the solution we have here." It was terrible.
