Pros

Great company culture, high code standards, high product security, global customers, plenty of opportunities to learn, using the latest cloud technologies.

Cons

The organization maintains high expectations, but there have been instances where deadlines were misrepresented by management, impacting planning and trust. Software architects often appear disconnected from day-to-day team activities, which can lead to misalignment and missed opportunities for support. The work environment can be high-pressure, with a risk of burnout if not carefully managed. Some team dynamics are affected by competitiveness and individualism, which can hinder collaboration. Additionally, there is room for improvement in how management supports team development and career growth. These challenges, combined with high employee turnover, suggest a need for more consistent leadership and stronger retention strategies.
