First call with HR about the position, salary expectations, etc. They said I would get a use case to do. Very simple use case, the hard part was doing the login implementation, otherwise straight forward. Second call was a technical interview, was very simple, more explanations of what the company does and the job consists. There was no talk about the use case. Third interview was with CTO, more explanations about the job and what the company tried to solve. Also asked about the salary expectations, which I understood that HR didn't pass that information. I replied, and then the CTO asked if I was earning something close to that. After these interviews there weren't any replies. Probably the salary expectations were to hight, seeing the look of the CTO...
