Flex Manager interview questions

wanted to know management capability and expertise . also ask a lot of questions about technical experience related to the position . very keen on asking questions about management style interaction with people in different groups etc.

Interview began at 1pm and ended at 4pm. No offer of a break in between. Interviewed throughout the day with several people from various functions. Everyone appeared to be open and honest about their perception of the company, which was not 100% positive. After the interview, f/u thank you emails sent to each person in the interview process. Followed up in email and phone calls to the manager & HR. So far, no response from either. Therefore, overall interview experience was negative because of the lack of common courtesy of a response to this job seeker.
