HotelKey Implementation Specialist interview questions

I appliled for the Implementation Specialist position. Interview was of 3 round. If one clear the first then they call for second round followed by HR round. I cleared all the three round of interview. Hr and in the second round (person was director operations) both discussed with me regarding ctc. Then hr asked me that I will get a call regarding joining dates nd further process. But they didn't communicate anything. I sent a follow up email but no response. One of the worst experience I faced in HotelKey. No professionalism, all they care about saving cost.
