Mercans Integration Project Manager interview questions

I was approached by recuriter and interview was scheduled. First round was technical and it went very well, the interviewer was very good and it was a 2 way conversation. Second round was formal, the interviewer asked only yes or No questions, like have you experience in this or that related to job role. I was asked to submit assignment after that round and then there was no update on assignment. When I followed up for feedback I got answer that the position has been held on hold and hiring team is silent on the matter. What I expect in such case is transparency, if the candidate has put so much efforts then a proper and timely feedback is expected. Rest is fine.
