Pros
You will have great coworkers, strong networks and potential to collaborate in philanthropy/social enterprise/social innovation spaces. Culture pros are that the team is open to new ideas and no toxic personalities. High level of discretion in making your role your own and you can go far in role in terms of gaining experience.
Cons
Operations and senior leadership struggle with making changes too rapidly to embed clear processes and practices, workplans chase funding rather than making sense from a management or capacity perspective and this leads to burnout of team. Not enough investment in PM infrastructure to sustain team management at the scale the organisation operates. Team structure needs to be overhauled or serious thought given to demands placed on staff beyond their job description. Culture of org normalises overworking at every level of the organisation, running to deliver against short deadlines or opportunities than being strategic. Performative consultation with staff at times, collation of feedback and data without a commensurate amount of learning.
