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

None - Mimecast leadership seems intent of stripping away all pros it once had

Cons

Treats AI like a people-replacement, not a tool Chaotic yearly layoffs Whole scale company direction changes every 6 months ELT revolving door, likely leading to the above points Constantly buying new technology - no longer an innovator or leader in the cybersecurity space
