Optum Senior Software Engineer interview questions

I was invited for the interview at DLF Cyber City Gurgaon. Once I reached there I had 2 technical rounds. I cleared all the technical rounds after that I had the managerial round and he asked me about my current CTC, expected CTC and the shift timings. As the shift timings in Optum was 2:30 pm to 12 am, he asked me are you comfortable for that timing. I said yes. After that he asked me to wait outside. After few minutes HR came and told me that all my rounds are cleared. I have to attend one more round that will be from onsite. After few days I received the invitation for the onsite round and that also went well. After that the HR asked to share all the relevant documents. I sent all documents and waited for the joining letter. It passed more than a week. Then I wrote a mail to the HR asking for the candidature update. The reply which I got from the HR was shocking. She replied we are reviewing other profile for this role. So it's my sincere request don't waste candidate time. If you can't give the expected CTC. Tell them clearly at the beginning.
