Steadfast Qatar interview questions

Interview was fine.. but after Interview they told I was selected. Then they called to next day and account explained the process and then HR asked if iam able to understand the process.. when I said I fine with the work process. They told me to next after Friday they will issue offer letter. After Friday.. Saturday and Sunday and 1 more day passed when I went back office to check for the update they told that position is on hold and they are not taking anyone.. lot of miscommunication between management and accountant
