HARMAN interview questions

There are 3 rounds of interviews , technical , manager, hr. In first round they asked me about technical questions . In the second round they asked me for the detail of my previous organisation

First Round - was with Harman internal where they asked about the core python skills and AWS. Second Round was with the Client MBRDI where they gave me coding questions related to python and Sql. Third Round - Purely AWS I had given the inteview well and was waiting for the feedback , HR came and informed that MBRDI had hold the position and they hired some one internally. The next week again HR reached out to me and said that they want to have me interviewed with some other postion for Backend with the same client. and same situation occured again the position was on hold and HR said the same that she will look in another team. They are just playing with the candidates hope and time. Either say yes or no. I will not recommed any one to give interview if your end client in MBRDI
