Celigo Project Manager interview questions

It started with case study round. They gave a case study and next round is based on that if case study is approved. I have been through more than 5 rounds and talked to almost 10 people in this process. They were good at the start to tell about result of previous round (not the feedback) but suddenly they stopped on what is the status and after multiple follow ups they updated that You are not selected because they have put my profile on hold. Advise - if you consider that interviewer time is important so does ours. You should let people know if they are not hold rather than for your benefit scheduling their further interviews
