I know in the academic system it is very important if one has completed his Ph.D. with a "summa cum laude" or not. At least if someone wants to go for a professorship position. Also, to try for such a title, one needs to have extra reviewers in his/her disputation. So, I was always advised by my supervisor not to try the hard case unless I know that I need "summa cum laude".
On the other hand, I do not want to stay in academia and want to build my career future in the industry (R&D section). By the way, I'm in Germany and my field is computer science. So, my exact question is how much that certain title is important or effective in finding a job in the industry or to climb up the ladder for a higher position in a company?
