Elsevier Account Manager interview questions

My interview process was 3 months long, there were three rounds. Cleared all three rounds, and HR asked for my documents. I have shared all the documents and waited for another two weeks for my offer letter. After two weeks I called HR and got the answer that there is some reconsideration related to this profile due to covid. I did not receive any written communication regarding the same. So for me, it was a frustrating experience and complete waste of time. Such type of behavior is not expected from MNC like Elsevier.
