First, the recruiter called me by phone and presented the position. We set the date for the second interview, which was with the manager. The interview lasted 30 minutes, and I received the typical questions. Shortly after, I received the invitation to the third phase, which was a demo presentation on a chosen topic. Five people participated in the presentation. I presented my topic, and I think I did well. The manager promised that I would receive a response within a week. More than two weeks passed before I received a generic email saying that I had not been selected for the position. I was surprised that after reaching the final phase, they didn't even bother to call me. The truth is, it is very unprofessional.
