CGI QA Automation Engineer interview questions

Gave 1st, had to wait for 2 hours to give interview at CGI hyderabad. After the interview, the HR was no longer at site and another informed that I have cleared the Interview and there would be another telephonic round on next Monday. Got a call from the HR saying she will schedule round 2 on Tuesday and that Tuesday never came. Sent 6 follow up emails, but No response from HRs, Pathetic HR, pathetic interview experience. Why to keep anyone waiting if you no longer intend to hire.
