When I started my internship, I was assigned a project. My internship mentor told he would just guide me if there was any problem. I started reading research papers and other works related to my project and completely understood it. But, when I started to implement my design, since then my mentor always order me to do things his way even though his method is crap. There are some things which can't be done but he wants results using his method (not possible). Because of him, I have lost all my interest from project. What to do?
