Pros

Working from home. This helps reduce daily exposure to a toxic internal culture.

Cons

There are significant and ongoing issues around diversity and inclusion at senior levels. Leadership and board composition lack meaningful representation, with very limited diversity and a noticeable absence of women in decision-making roles. • Despite strong external messaging around values and inclusion, the internal reality does not reflect this. DEI initiatives feel performative rather than embedded in accountability or leadership behaviour. • Culture is hierarchical and political, with progression often driven by informal networks rather than transparent, merit-based processes. • Speaking up is not psychologically safe. Challenging the status quo is discouraged, and concerns are frequently minimised rather than addressed. • High levels of disengagement and turnover are treated as normal rather than as warning signs.

Pros

Great benefits like health insurance coverage and dental benefits. Good work life balance

Cons

Felt tricked into the organization with an attractive initial salary but no growth opportunities, no annual bonus, no annual increments. So left for better offer.

Pros

The location was nice. The office ended up going through a renovation, Covid happened, and then they laid me off and the office totally shut down.

Cons

No one was ever in the office. My manager was usually traveling.
