In my experience, yes, big companies are boring. Sometimes a particular department might be good, but most of the jobs are boring. There tends to be many levels between you and the people making the actual decisions and you have little input. There is usually a large bureaucracy with a large number of busy work tasks. Being rewarded for you contributions (or just being rated accurately) is not a given and can lead to disappointment. There's really no avoiding it. You're trading your life for money - that's how jobs work from an employee perspective.
