Xerox Senior Software Engineer interview questions

I had the worst interview experience with Xerox. I was interviewed for more than 2 hours and informed that I have been shortlisted for the position. Also I was told to share the experience and other related documents. Later without any update they sent me a mail saying they are proceeding with other candidates. Such an unprofessional way of interviewing. If they cannot afford my salary expectations, why would they shortlisted me? Please don't waste candidates time and effort if you don't have the capacity to meet the expectations.
