Ingenus Pharmaceuticals interview questions

Four individual interviewers. One is HR (asking about salary and the typical interview questions) the other three focused on technical questions. The interview was very technical in the sense that you are being tested/quizzed more than going through last experience. One interviewer was rather insulting and unprofessional (calling me a little boy which is just a beyond weird way to behave). Salary also was below market based on General information I gleaned from HR.
