Preguntas de entrevista para el cargo de Java Developer en Fluid AI

It's a very boring process. There was a five rounds of interview. First is pen and paper coding round that everyone can easily cleared. After that there was a aptitude test depends on logical AI and java questions. And after that there was a coding (machine) round which was difficult to clear. I cleared upto this round only. But I don't recommend any fresher to go here because hr is not cooperating and process of quite long and its just a waste of time.
