The first interview with the HR is very pleasant, as well as the second one with the technical manager. They ask me to write them a brief feedback about it, which I do shortly after the second interview, since I was very interested in the job. However, afterwards I don't heard from them for one month. When I reach out asking for updates, they tell me that they had just finished the interviews, and that they would be in touch with me soon. After two weeks of silence, I receive an authomatic message stating that I was not available for another interview, so I reach out again asking for explainations and they tell me that the position had been filled internally.
