The interview process was fine. First with the HR recruiter, I did a test to show my knowledge about the requirements for the position and them two interviews with the position manager. The problem was after being approved. I received the job offer, signed and then I received an automatic email from the company system saying that the offer was cancelled. I didn't know if it was a mistake. I just got an answer from HR some days later, after sending some emails. They said that the owner of the company simply decided to promote a internal employee.
