Full of egos and useless externally hired middle management - Implementation Consultant AppNexus Employee Review

They make a lot of management hires externally rather than interally, kills morale. Egos get in the way of making sensible business/product decisions Employees tend to keep knowledge to themselves, very much a "every person for themselves" attitude. Very long hours are the norm and they expect you to sacrifice your personal life for the good of the company, which is fine if the compensation was better.
