Has 3 rounds.Interview was very good.Mainly focussed on what was previous experience.How much I can contribute to new role and my interests to join Amadeus

HR contacted me to establish a date for a phone interview by the hiring manager. I was unable to do the day and time suggested so I was advised that I would be contacted the next day with the new date. I was not ccontacted until the day prior to the interview. The interview went well and the manager stated he would contact HR and I should hear something from them. I sent thank you notes to both HR and the hiring manager. never heard from HR so after 2 weeks I contacted HR but no response. A week later I contact HR again who responded that she had not received any information regarding the job and would check with the hiring manager and advise. It has been a month and still no word regarding the job.
