Pros

Overall great for sales and developing career in tech. not all territories perform well but if you work hard you can do well.

Cons

Not always transparent or the correct systems in place for rolling out new things. Can be cut throat/higher pressure salesy but managers are open to work life balance but it’s still sales at the eod

Pros

The offices are nice, and there are some perks—especially now, after a large round of redundancies, designed to make the remaining employees feel better.

Cons

The environment is chaotic, heavily influenced by politics. Success is less about your dedication or the quality of your work and more about pleasing a select few with power. Teamwork is poor, and there’s a lack of a cohesive vision. Some individuals exhibit toxic behavior, even causing emotional distress. Leadership is weak, and stability is lacking. As the company loses its competitive edge, redundancies are becoming more frequent and numerous.

Pros

Great exposure to complex international compensation and benefits work. Many talented peers who are collaborative and genuinely care about doing the right thing. Opportunities to lead cross-regional projects and influence reward strategy.

Cons

Internal HR controls and governance lack consistency; processes can be overridden without proper oversight. Limited empathy and psychological safety when raising concerns — support often feels transactional rather than human. Management culture prioritises control over trust; feedback and development conversations are often promised but not delivered. International employees can feel isolated from leadership decisions and less visible than US-based peers.
