HARMAN Senior DevOps Engineer interview questions

There were 2 rounds of interviews. I cleared both of them but at the end I never received the offer letter they just kept on delaying and finally said that they retained the person who was working in the same position they wanted me to hire for and it is no more available. Then they wanted me to give interview again for another project. I requested them if they could take my previous interview result they did not agree, finally I said them I am ready to give the interview. But they never scheduled any interview after that.
