Used is an understatement - Mitarbeiter (anonym) bei Proventeq: Mitarbeiterbewertung

With no doubt the worst place I ever worked for . They use you like slaves and give you a task one day then next day ask why you’re doing it - the bosses have no plan or memory or joined up approach at all . This makes it so stressful so I had to quit . Lots of these earlier reviews which are positive are manufactured by HR - they asked people to write them, I heard them do this
