Bekaert Project Manager interview questions

Very lenghty interview process over a period of almost three months. All face to face interviews. After third round they called me and asked me to come for final 4th round. After attending 4th round then told me that result will be announce in a week. They call me after 10 days and asked me to come again for another three rounds of interview discussion. Reason - They want to ask more question. The final round was technical and the lady only conducted interview for 7 min. Not well planned and very unprofessional. You conduct interview for 7 min and then again call for interview to ask more questions. HR asked for CTC and then never comes back with the feedback. Earlier the panel had mentioned that budget is not an issue. I kept patience through this process, the HR didn't care to call me for few min and share the honest feedback. Bad attitude, unprofessional behaviour. Glad that I have recieved another offer.
