Pros
Fast-paced work environment: New / different tasks arise (almost) everyday which makes the work stimulating and fun. Taking over responsiblity: Commitment and willingness to learn are rewarded with the freedom to work independently on (big) tasks and bring in own suggestions and ideas. Supportive atmosphere: Opportunity to learn from and discuss with experienced managers who take feedback and your development seriously. Hierarchical and departmental structures cannot be felt during daily interaction with co-workers which makes it easy to approach and talk to others in the office. Integration and collaboration is facilitated through weekly / monthly (in)formal team meetings.
Kontras
Rather a heads up than a minus: The nature of company and work require flexibility, proactivity and open-mindedness. If you tend to pay attention to detail, you might sometimes struggle with the 'done is better than perfect' attitude that comes along with the fast-paced working environment.
