Companies say this in many different ways. One simple way is to state the accomplishments of the company as a whole and make it look like you were (or are) a major part of the past (or future) accomplishments.

A quick example. Take a look at a career advertisement on a bill board for Yahoo!. The bill board says

1 out of every 2 people online
WILL LIVE YOUR CODE

One can take this literally and be in the fantasy world that 1 out of 2 people online are REALLY living their code. I hope nobody does that. Probably Yahoo! knows that too.

My point:

I think it is a given that you should be proud of working for the company you are working for. Otherwise, why work there?

What really matters is – “Is the company you are working for proud that you are working for them?”
