Another old school staffing company - Mitarbeiter (anonym) bei Software Management Consultants: Mitarbeiterbewertung

They have passive aggressive management who seem very fake. Only 1% of the people make a lot of money while everyone else makes nothing. And there's no incentive for you to work harder since their commission structure is so confusing and horrible. They also love giving you lip service to make you happy and they turn around and do another thing.
