Pros

A small number of original staff still employed and genuinely want the product to succeed.

Cons

Many use the business purely for career progression. Often enjoying overly inflated job titles, and the feeling of being untouchable because of who they know.

Pros

Great office, catered lunch daily. Great benefits, 4 weeks PTO to start plus paid holidays, floating holidays, sick time. Culture is flexible, vibrants, friendly people.

Cons

Frequent changed and pivoting but senior leadership listens to employees which is good.

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.
