Pros

Good salary and met nice people

Cons

Micromanagement is looked at under a microscope. An old-fashioned way of doing the job, not allowing room for modern methods to be taken into consideration in metrics. Very rigid KPI structure. Not having a voice at all in improving methods - often felt with bigger companies, but have not been able to speak your mind as management would just brush it off and feel like 'that's a you problem' more often than not.
