Ramiz bro I don't think "Noting" mean "An order to issue appointment letters".
If the information provided by Sami is correct then my information is not contradicting it. Noting is just another step in the process and the next step might be board's decision. Those working in govt. departments might know it better.
So if Sami's information is true then this is a good news that another step has been taken in the recruitment process. Now the next might be the final step I think "The decision by board of directors". And yes this can take more time, but it can even take only one week, it depends upon the Board of Directors. HR department doesn't know what BOD is going to do.
I just hope Sami's informatiion is correct.
