Mphasis Senior Mainframe Tester interview questions

Very bad experience. Set up the first round interview only they cancelled scheduled interview 5 times. After first round of technical interview I got call from HR and mentioned like your selected, will you be available tomorrow for interview with delivery manager( 2nd round). Then suddenly said panel is not available. Then after 1 week called to HR and ask the status. When i called both the HR didn't reply. Then I WhatsApp one of them. She said your rejected. I asked the reason but still i didn't get it. Its completely strange because they only mentioned your selected and later your rejected. I felt its time pass interview.
