      Toxic culture and poor leadership overshadow few positives

      Pros

      The people (some) Struggling to find more

      Cons

      Mimecast used to be a great place to work with good tech and strong values. The culture is toxic and incredibly unhealthy. They will promote you without an increase in pay. Recognition is a joke. The CEO is actively running the company into the ground. Sales leadership repeatedly meddles into and destroys sales opportunities and turns around to blame the sales team. The product is a mess with no strategy. only thing that's clear is the direction in which it is going, down.
