Good overall atmosphere on the actual interview. Though the process was simplified for me because i didn't went through the HR interview but did a preliminary test in which i had to make simple ai applications. In the interview there were simple questions about compiter vision. But even though i messed up a question about fft and wasn't picked afterwards, i still think it's a good company and would reccomend it.
A tip for anyone that is going through the same stuff would be to please the CEO no matter what and give him many questions. He seemed to like the fact that i am interested in his goals and story so good luck.
