Agreed, in fact I'd go as far as to say after 2 years you should have a pretty good feel for the environment and have an idea if there is room for growth. Some companies propagate a culture of mediocrity where everyone is just there to collect a paycheck and go home. If you can recognize that sentiment early on, its best to distance yourself to avoid getting sucked in and resigning yourself to the "do enough to get by" mentality.
