Hologic Senior Software Engineering interview questions

The interview wasn't arranged well, change the schedule all the time. Workplace is kind of mass, more like a startup but will not share the profit with employees as a startup. Engineers there is OK, but management seems not that professional. For a company has more than 3000 people, they are still using some low efficiency management method. Less than 80 people are currently working on R&D which is < 2.7%. It surprised me how they are going to survive in the industry. Human resource person is not professional at all, always bring out the salary questions although I told her my current salary at the beginning. It seems to me she is a junior recruiter and want to get some credit or something. Basically she even can't arrange the interview process very well. Job hunter need to pay attention to company like HoLogic. Do not wast your time on it.
