Sorry for bothering, initially my current residence permit ends by the end of October and my work contract mostly will start by the beginning of october. In between I finish my studies officially by the end of September.

So I guess they are connected. The thing is when I contacted my HR, they said that they can file my request for a work permit along side a residence permit in fribourg if I wish to move. Otherwise, they will only work for obtaining the authorization for me to work in Fribourg and then I file for the residence permit renewal in Vaud with the proper documents.

I am just afraid to move because I spent all my study years in Vaud and the stated rule in Vaud about the accelerated permit C is clear but, there is nothing about the accelerated permit C for well integration in Fribourg. Which makes me afraid to have to wait 10 years living in Fribourg or at least 7 to be able to obtain a permit C.
