Vantaggi
Colleagues are very knowledgeable; Managers respect the workers and know how to manage the workload. All the situations where I saw some teams lagging behind the managers were very supporting and stood for their direct reports. There is a great life balance. The work environment is incredibly healthy. Generally this is a company which deeply understands that nurturing the well-being of the employee is nurturing their bottom line.
Svantaggi
very competitive environment for career progression. It is difficult to develop yourself since some people try to get ahold of a specific area and dominate it (even by making your own work difficult - e.g. purposely postpone code reviews, constantly iterating over small things in code reviews, not disclosing the full details on some part of the code or past issues faced... )
