The company is very money based. Last few years they have got rid of poisonous management which was well needed, but now all they care about is how much money you can bring in. It is a competitive environment in a way where job security is leverage on that single fact.
No innovation has came from them in the time I have been working there. They are on the way to be another average OOH company that sticks to old ways and won't change with the the current times.
Don't except ideas to reach higher levels and actually be implemented. Unless you work at the corporate office, you are another pawn.
I believe that the reason why Signal is now money hungry is because a sell off is very near in the future.
