Pros

Unfortunately I can’t (and neither can my friends that still work there) find many positives right now. The company seems to be imploding to a degree. Working at MIME used to be a transformative experience that would set the tone for your entire career. I’m sure there’s at least one or two places there where that still applies.

Cons

Aside from the Solarwinds fallout, all I hear from anyone that still works there is... it’s not the same. I can’t speak from the technical or support side, but in sales there is very much a command and control culture. That culture is perpetuated by leadership (mostly legacy RSA) and I can say for sure that their mora compasses do NOT point directly north. There’s a reason that everyone from channel to sales to SE’s, etc. have left in the last year. As things get worse, the leadership doesn’t try to galvanize the team and bring everyone together. Their approach is to pull the reins tighter and introduce MORE metrics... more daily stand-up meetings... it’s unfortunate, but that style of leadership is reaping what it’s sown for quite a while.

Pros

The people at Mimecast are truly the best part of the company. Coworkers are smart, collaborative, and genuinely supportive, even during times of uncertainty. There's a strong sense of camaraderie within teams, and many individuals go above and beyond to help each other succeed.

Cons

Mimecast recently conducted large-scale layoffs, impacting a significant portion of the workforce with very little warning. This has created an atmosphere of instability and uncertainty across the company. Leadership has demonstrated a pattern of over-hiring and making aggressive acquisitions, only to turn around and cut roles without clear strategy or foresight. These sudden changes are deeply disruptive, not only to business continuity but more importantly to the lives and livelihoods of employees and their families. The company appears to be struggling financially, and this instability is reflected in unclear direction, shifting priorities, and a lack of transparency from senior leadership. For those seeking a stable, long-term opportunity, this is not the right place for you. Job security is a growing concern, and morale has taken a noticeable hit.
