Preguntas de entrevista para el puesto de Software Engineer - Java Developer en Deep Sea (Greece)

First I had an initial call with the HR, then I was assigned to complete a small project with an excel and some statistic exports, after that I was interviewed with the TLs with questions about the task. I received no feedback after the 3rd interview which I believe is pretty bad as I had already completed the task and reached to 3rd call
