Preguntas de entrevista para el puesto de Senior Software Engineer - Java Developer en Servosys Solutions

I had interviewed at Servosys solution. The process was very lengthy. I reached at 12pm and left the office at 7pm. They had total 4 rounds. I cleared almost all the rounds but the last round with technical architect was very hectic. They keep you waiting the entire day for no reason and the interview process is worst
