Pros
Higher management are extremely approachable, friendly and supportive. The firm's overall environment is very inviting and provides employees with a sense of security. The company culture lends itself to creating long-term employment relationships meaning even employees who are struggling receive the support required to set them on track to achieve their yearly objectives. The career growth opportunities are vast should you be ambitious enough to seek it.
Cons
There is no rigid structure in the sense that employees positions are fluid and flexible (note: this can also be a pro in the sense that if you are feeling unhappy and would like to try something new - the option is available). For those that value stability, this may be unsettling but nevertheless an opportunity to expand your experience and knowledge.
