P.I. Works Software Support Engineer interview questions

There is a technical interview with following hr interview, department head interview and ceo interview. I have encountered technical problem over the technical interview and department head interview. Even department head want to repeat same interview. Eventually I attended two interview with the department head.

after i applied for this role, i received an email to complete the online assignment which has to be completed within 3 business days. i answered all the questions but my application was unsuccessful. no reply from them when i asked the reason for it. at least they could have given me chance for a face 2 face interview. they are testing the market without any intention to hire anyone i guess.
