Imagine going on a date and after the fourth time being like "I still don't know if I like you, need more tests". I tend to get impatient with companies who ask for yet another round of interviews because I think either they like me or they don't. Maybe the issue is too risky to employ somebody? In my country a lot of laws protect employees, so it might be difficult to get rid of bad hires (although in the first 6 months I think it is easy, as they count as probation period).
