Infosys Consultant interview questions

I got referred for the post of Consultant. There was one round of technical process which was almost in my realm of the work I do. After the technical process, I get to know that I am shortlisted and the HR will contact me. The next process was the background checks for which I provided all the documents that the HR requested from me so that they can contact me and do all further negotiations stuff. After 5-6 days, I directly got a rejection mail from the Talent Acquisition team with an ambiguous reason. After couple of follow-ups, I got to know that my salary expectation was more. One request to the hiring team that please provide a chance to the interviewee for negotiations and stuffs. Also, please provide a proper closure to the interviewees.

HR reached out to me and ask for more information (e.g. salary expectation). After going through all 4 interviews (4 hours + prep time), they then offered me the job however can't meet my salary expectation. There is NO room of negotiation at all.
