When u go with a good Name of a company the client comes to you because of your name and you dont have to do the initial presentations to convince the client.
But in case of a startup company we have to convince the client. This helps us undertand the project in detail since the stake of the project is more and the fear of losing the project makes u work.
I guess the same is with good colleges. When a part of a good college we generally tend to put less efforts because we know we will get a job anyways. But when u come from a small college you have a tendency to put more efforts from your side because the only way to get a good job is by what you are
and not what your college is.....think about it
