The first round was a "written" test of 6 questions. Very basic and irrelevant for any developer. The second round was taken by two Engineers. They asked irrelevant questions from textbooks. They said they are testing basics but it was not enough to test an experienced candidate as no one will know the exact definition they are expecting. The culture of the company seems very bad as the interviewers were very rigid and never really listened to the explanation you give and tried to act very superior and arrogant.
