Avantages
You get out of it what you put into it. Autonomy and responsibility if you are fluent in the principles of extreme ownership. Think of it like running your own business as an entrepreneur, with a deep well of resources at your fingertips to help you be successful. High upside if you are willing to put in the work! (and that doesn't mean 50 hour weeks or unmanageable workloads)
Inconvénients
If you don't have an open mind, are closed off to learning new things, and don't have a "how can I help" mentality, this may not be the best fit for you. Pay (base salary) may be slightly lower than other consulting firms, but total rewards package in the aggregate is competitive, and high upside potential with career path opportunities.
